3 April 1933: Squadron Leader Douglas Douglas-Hamilton, Marquess of Douglas and Clydesdale ¹ (Lord Clydesdale)—at the time, the youngest squadron leader in the Royal Air Force, and in command of 602 Squadron—as Chief Pilot of the Houston Mount Everest Flying Expedition, flew a modified Westland PV-3 biplane, G-ACAZ, in formation with Westland PV-6, G-ACBR, over the summit of Mount Everest, the world’s highest mountain, elevation 29,029 feet (8,848 meters). The PV-6 was piloted by Flight Lieutenant David Fowler McIntyre, also of 602 Squadron.
The two airplanes took off from Purnia, in the northeast of India, at 8:25 a.m. Aboard Lord Clydesdale’s airplane was observer Lieutenant Colonel Latham Valentine Stewart Blacker, O.B.E. (“Blacker of the Guides”), and on McIntyre’s was Sidney R. G. Bonnett, a cinematographer for Gaumont British News. During the ascent to Everest, Bonnett damaged his oxygen hose and lost consciousness due to hypoxia.

The Bristol Pegasus S.3 was considered to be the only aircraft engine in the world that would be capable of powering an airplane with the necessary personnel and equipment high enough to fly over Everest. It was an air-cooled, supercharged, 1,752.79-cubic-inch-displacement (28.72 liter) nine-cylinder radial engine, with a compression ratio of 5.3:1. It had a Normal Power rating of 525 horsepower at 2,000 r.p.m. at 11,000 feet (3,353 meters), and produced a maximum of 575 horsepower at 2,300 r.p.m. at 13,000 feet (3,962 meters). It had a Takeoff Power rating of 500 horsepower at 2,000 r.p.m. at Sea Level, with a three minute limit. The engine drove a two-bladed, fixed-pitch wooden propeller manufactured by The Airscrew Company Ltd., through either a 0.5:1 or 0.655:1 gear reduction.
After deciding on the engine, the Expedition had to select an airplane. The Westland PV-3 was chosen because it had the highest rate of climb of any airplane ever tested by the Royal Air Force.

The Westland Aircraft Works PV-3 was a private venture prototype torpedo bomber, based on the earlier Westland Wapiti. It had an all-metal structure and folding wings. Only one was built, and no orders for the airplane were placed. The airplane was modified for the Houston Everest Expedition. The gunner’s open position behind the pilot’s cockpit was replaced with an enclosed cabin for an observer and cameras. The original Bristol Jupiter X.FA engine was replaced by the more powerful Bristol Pegasus S.3 and a large-diameter propeller.
The Houston-Westland was 34 feet, 2 inches (10.414 meters) long with a wingspan of 46 feet, 6 inches (14.173 meters) and overall height of 11 feet, 8 inches (3.556 meters). The airplane had an empty weight of 3,420 pounds (1,551.3 kilograms) and loaded weight of 5,100 pounds (2,313.3 kilograms).
The PV-3 had a maximum speed of 163 miles per hour (262.3 kilometers per hour) and a service ceiling of 35,000 feet (10,668 meters). Burmah-Shell provided a special fuel for operations at very high altitude.
Westland PV-6 G-ACBR
The Westland PV-6 was also a private venture prototype. It was later converted to the Wallace I configuration.
The airplanes carried Williamson Automatic Eagle III survey cameras that would take photographs of the surface at specific intervals as the airplanes flew over known survey locations. It was planned that a photographic mosaic of the terrain and an accurate map could be drawn.

The expedition was financed by Lucy, Lady Houston, D.B.E., who offered to provide up to £15,000 to finance the project. The flight helped to demonstrate the need for specialized equipment for high altitude flight.
For his accomplishment, Lord Clydesdale—later, Air Commodore His Grace The Duke of Hamilton KT GCVO AFC PC DL FRCSE FRGS—was awarded the Air Force Cross.

Mount Everest, known in Nepal as सगरमाथा (Sagarmāthā), is a mountain in the Mahalangur Range of the the Himalayas. Its peak is believed to be the highest point on Earth. The mountain was “discovered” by the Western world in 1856, during the decades-long Great Trigonometrical Survey of India. Identified as Peak XV, the height of the mountain was measured at 29,002 feet ² (8,839.8 meters) above Sea Level. The Royal Geographical Society named the mountain Everest after Colonel Sir George Everest, FRS, FRAS, the Surveyor General of India from 1830 to 1843. At present, the agreed height of Everest is 8,848 meters (29,029 feet). The upper portion of the mountain is primarily marble and is covered by several meters of ice and snow.

¹ In 1940, Lord Hamilton succeeded his father, Lieutenant Alfred Douglas Douglas-Hamilton, 13th Duke of Hamilton and 10th Duke of Brandon, as 14th Duke of Hamilton and 11th Duke of Brandon.
² Interestingly, in The Map Makers (John Noble Wilford, Alfred A. Knopf, New York, 1981), it was reported that the Great Survey actually calculated the height of the mountain at 29,000 feet (8,839.2 meters), but it was felt that this value would be taken as an approximation rather than an exact value, so 2 feet were added, resulting in the generally known height of 29,002 feet (8,839.8 meters).
The elevation of the summit may have changed due to a Magnitude 7.8 earthquake that occurred 25 April 2015, and a M 7.3 aftershock on 12 May 2015. Nepal and China both conducted an elaborate survey in 2020. Nepal used the Bay of Bengal as Sea Level, while China used the Yellow Sea. They agreed that the height of the summit of Mount Everest is now 29,032 feet (8,848.86 meters).

3 April 1926: Virgil Ivan Grissom was born at Mitchell, Indiana, the second of five children of Dennis David Grissom, an electrician, and Cecile King Grissom. “Gus” Grissom attended Mitchell High School, graduating in 1944. He was a member of the Hi-Y Club, the Camera Club, and the Signal Club.
Upon graduation from high school. Virgil I. Grissom enlisted as an aviation cadet in the Air Corps, United States Army, at Fort Benjamin Harrison, Lawrence, Indiana, 9 August 1944. He was assigned to basic flight training at Sheppard Field, Texas, but the War came to an end before he could graduate as a pilot. Then reassigned as a clerk, he requested to be discharged from the Air Corps, which he was in November 1945.
Grissom married Miss Betty Lavonne Moore at Mitchell, Indiana, 6 July 1945. They wood have two sons, Scott and Mark. (In Korea, Grissom named his F-86 Scotty after his first son.)
After the war, Grissom enrolled at Purdue University, Lafayette, Indiana, and in 1950, graduated with the degree of Bachelor of Science in Mechanical Engineering.
He then re-joined the U.S. Air Force in 1950 and was trained at Randolph Air Force Base, Texas, and Williams Air Base, Arizona, where he specialized as a fighter pilot. He was commissioned as a second lieutenant, U.S. Air Force, in March 1952.
Lieutenant Grissom was assigned to he 334th Fighter Interceptor Squadron, 4th Fighter Interceptor Wing, based at Kenpo Air Base (K-14), in the Republic of South Korea. He flew 100 combat missions in the North American Aviation F-86 Sabre. Grissom was promoted to first lieutenant, 11 March 1952. he requested to fly another 25 combat missions, but that was declined and he returned to the United States. Lieutenant Grissom was then assigned as a flight instructor at Bryan Air Force Base, Texas.
Grissom attended a one year program at the Air Force Institute of Technology at Wright-Patterson Air Force Base, Dayton, Ohio, and earned a second bachelor’s degree in aircraft engineering. He was then sent to the Air Force Test Pilot School at Edwards Air Force Base, California (Class 56D). After completion, he was assigned as a fighter test pilot back at Wright-Patterson.
One of 508 pilots who were considered by NASA for Project Mercury, Gus Grissom was in the group of 110 that were asked to attend secret meetings for further evaluation. From that group, 32 went on with the selection process and finally 18 were recommended for the program. Grissom was one of the seven selected.

Major Grissom was the second American to “ride the rocket” aboard Mercury-Redstone 4. He named his space capsule Liberty Bell 7. The spacecraft reached a maximum altitude of 102.8 nautical miles (118.3 statute miles, 190.4 kilometers) and traveled 262.5 nautical miles (302.1 statute miles, 486.2 kilometers) down range. During the 15 minute, 37 second, flight, Grissom was weightless for 5:00 minutes.
Next he orbited Earth as commander of Gemini III along with fellow astronaut John Young. He was back-up commander for Gemini VI-A, then went on to the Apollo Program.

Gus Grissom was selected as the commander for Apollo I in January 1968. This was to be the first manned flight of the Apollo spacecraft. Ed White and Roger Chaffee were the other members of the flight crew.
As commander of AS-204 (Apollo I), LCOL Virgil I. Grissom, USAF was killed along with Ed White and Roger Chafee during a test on the launchpad, 27 January 1967.

Gus Grissom was an Air Force Command Astronaut with over 4,600 hours flight time. He was the first American astronaut to fly into space twice, and logged 5 hours, 7 minutes of space flight. For his military service, Grissom was awarded the Distinguished Flying Cross; the Air Medal with one bronze oak leaf cluster (two awards); the American Campaign medal; the World War II Victory Medal; teh Korean Service Medal; the United Nations Korea medal, and the Korean War Service Medal of the Republic of South Korea. For his NASA service, he was awarded the Congressional Space Medal of Honor (posthumous); the NASA Distinguished Service Medal (two awards); and the NASA Exceptional Service Medal.
Had he lived, it is very possible that Grissom would have commanded the first Apollo mission to land on The Moon.
The remains of Lieutenant Colonel Virgil Ivan Grissom, United States Air Force, NASA Astronaut, are buried at the Arlington National Cemetery, Arlington, Virginia.
Northwest Airlines, Inc., Boeing 377 Stratocruiser N74608. (BAAA)
2 April 1956: On Monday morning at 8:10 a.m., Pacific Standard Time, Northwest Airlines Flight 2 took off from Seattle-Tacoma Airport en route to New York City, with intermediate stops at Portland, Oregon, and Chicago, Illinois. The airliner, a Boeing 377 Stratocruiser, N74608, had a crew of six and carried 32 passengers. The flight was under the command of Captain Robert Reeve Heard, with First Officer Gene Paul Johnson and Flight Engineer Carl Vernon Thomsen.
The weather at “SeaTac” was overcast, with a ceiling at 1,200 feet (366 meters) and 10 miles (16 kilometers) visibility. The wind was from the east-northeast at 7 knots (3.6 meters per second).
The Boeing reached the cloud layer at 145 knots (167 miles per hour/269 kilometers per hour). The engines were throttled back from takeoff power and the wing flaps were retracted. The airplane suddenly began to buffet severely, as if it were about to stall. (A passenger later said that the airplane “shook like a wet dog.”) It also rolled to the left and Captain Heard had to use full opposite aileron to maintain control. N74608 began to lose altitude.

Captain Heard suspected a split-flap condition, in which, one of the flaps remained partially or fully extended. Initially considering a return to SeaTac, Heard decided that it would be safer to proceed to McChord Air Force Base. The situation continued to worsen. Captain Heard, fearing control would quickly be lost, decided to ditch the Stratocruiser in Puget Sound.
N74608 hit the surface 4.7 nautical miles (5.4 statute miles/8.7 kilometers) from the end of Seattle’s Runway 20, The water was smooth and the airliner coasted to a stop. It then began to take on water. All passengers and crew were evacuated. Two passengers suffered minor injuries. Once in the water, they used seat cushions for flotation. (Flight 2 was not required to carry rafts or life vests.) The water temperature was 42 °F. (5.6 °C.). After about fifteen minutes, the Stratoliner sank in 430 feet (131 meters) of water.
A Northwest Airlines DC-3 flew over the scene and dropped three life rafts. Two U.S. Air Force Grumman SA-16 Albatross amphibians and a U.S. Coast Guard 83-foot (56.6 meters) patrol boat soon arrived on scene. Most of the passengers and crew were rescued. However, four passengers, probably suffering from hypothermia, had drowned. Flight Service Attendant David Victor Razey was missing. The accident occurred on his 27th birthday.¹

The wreck of N74608 was located on the floor of Puget Sound. It was initially moved to shallow water where divers were able to examine it. Later, the airliner was lifted onto a barge.
The Number 1 engine is missing. (Civil Aeronautics Board)
The Stratoliner’s Number 1 engine (outboard, left wing) was missing and never found. Investigators found that the cowl flaps of the remaining three engines were all fully open. They should have been closed for takeoff.
When the flight crew went through the pre-takeoff check list, in response to the prompt, “Cowl flaps set for takeoff,” the flight engineer responded, “Set for takeoff,” when they were actually open.
At takeoff and climb out speeds, open cowl flaps disrupt the flow of air over the wings. With the wing flaps down, this isn’t noticeable, but when the flaps are retracted, a severe buffeting occurs, as parts of the wing begin to stall.
Investigators found “no failure or malfunction of the aircraft, the power plants, or control systems prior to the ditching.”
Probable Cause:
The Board determines that the probable cause of the accident was the incorrect analysis of control difficulty which occurred on retraction of the wing flaps as a result of the flight engineer’s failure to close the engine cowl flaps—the analysis having been made under conditions of great urgency and within an extremely short period of time available for decision.

Northwest Airlines’ N74608 was one of ten Boeing Model 377-10-30 Stratocruisers ordered by the airline. It was built at Seattle, Washington, in 1949, and assigned the manufacturer’s serial number 15954. N74608 carried Northwest’s fleet number, 708. The 377-10-30 was a variant built specifically for Northwest. It can be identified by the rectangular passenger windows.
At the time of the accident, the airliner had flown a total of 18,489 hours (TTAF).
The Model 377 was a large, four-engine civil transport which had been developed, along with the military C-97 Stratofreighter (Boeing Model 367), from the World War II B-29 Superfortress long-range heavy bomber. It utilized the wings and engines of the improved B-50 Superfortress. The airplane was operated by a flight crew of four. It was a double-deck aircraft, with the flight deck, passenger cabin and galley on the upper deck and a lounge and cargo compartments on the lower. The airliner was pressurized and could maintain Sea Level atmospheric pressure while flying at 15,500 feet (4,724 meters). The Model 377 could be configured to carry up to 100 passengers, or 28 in sleeping berths.
The Stratocruiser was 110 feet, 4 inches (33.630 meters) long with a wingspan of 141 feet, 3 inches (43.053 meters) and overall height of 38 feet, 3 inches (11.659 meters). The airliner had an empty weight of 83,500 pounds (37,875 kilograms) and the maximum takeoff weight was 148,000 pounds (67,132 kilograms).

N74608 was powered by four air-cooled, supercharged, 4,362.49-cubic-inch-displacement (71.488 liter) Pratt & Whitney Wasp Major B6 engines. These were four-row, 28-cylinder, radial engines with a compression ratio of 6.7:1.
The B6 had a Normal Power rating of 2,650 horsepower at 2,550 r.p.m., at 5,500 feet (1,676 meters), and Maximum Continuous Power rating of 2,800 horsepower at 2,550 r.p.m. at 3,500 feet (1,067 meters). The Takeoff Power rating was 3,500 horsepower at 2,700 r.p.m. with water/alcohol injection.
The engines drove four-bladed Hamilton Standard Hydromatic 24260 constant-speed propellers with a diameter of 17 feet (5.182 meters) through a 0.375:1 gear reduction.
The Wasp Major B6 was 4 feet, 7.00 inches (1.397 meters) in diameter and 8 feet, 0.50 inches (2.451 meters) long. It weighed 3,584 pounds (1,626 kilograms), dry. The propeller assembly weighed 761 pounds (345 kilograms).
In this photograph of the Boeing 377 assembly plant, the airplane’s cowl flaps are visible immediately behind the engines. (Boeing)
The 377 had a cruise speed of 301 miles per hour (484 kilometers per hour) and a maximum speed of 375 miles per hour (604 kilometers per hour). During testing by Boeing, a 377 reached 409 miles per hour (658 kilometers per hour). Its service ceiling was 32,000 feet (9,754 meters) and the range was 4,200 miles (6,759 kilometers).
Boeing built 56 Model 377 Stratocruisers, with Pan American as the primary user, and another 888 military C-97 Stratofreighter and KC-97 Stratotankers.
¹ David Victor Razey was born 2 April 1929 at Maerdy, Rhondda Cynon Taf, Wales. He had brown hair, hazel eyes and a medium complexion. He was 5 feet, 5 inches (1.65 meters) tall and weighed 140 pounds (63.5 kilograms). Razey became resident of the United States in 1949, and was naturalized as a U.S. citizen, 2 August 1954.

2 April 1944: The first Boeing B-29 Superfortess to arrive in the China-Burma-India Theater was B-29-10-BW 42-6331, Gone With The Wind, under the command of Colonel Leonard F. Harman, commanding officer, 58th Bombardment Wing (Very Heavy). 42-6331 landed at Chukulia Airfield, south west of Chukulia, India, after a 7-day journey. 42-6331 had departed Pratt Army Airfield, about 45 miles (72 kilometers) west of Wichita, Kansas, on the morning of 26 March 1944.
From Kansas, Gone With The Wind flew non-stop to Gander, Newfoundland. It then crossed the Atlantic Ocean to Marrakesh, Morocco, on the northwest shoulder of the African Continent. Next, the B-29 crossed North Africa to John Payne Field at Cairo, Egypt, and then on to Karachi, India (now, Pakistan). The final leg was to Chikulia, in the Purbi Singhbum District of the State of Jharkhand, India.

Gene Gurney wrote:
“According to schedule, all the B-29s were to arrive between the first and the fifteenth of April. At noon, Sunday, April 2, at Chikulia, General Kenneth B. Wolfe, commander of the 20th, and his staff assembled to await the arrival of Harman’s plane. Twice before false alarms had brought them rushing to base operations, but this time Colonel Harman himself had radioed his ETA—estimated time of arrival. Because this was a “historic” first, public relations officers staged an elaborate welcome with a fighter escort aloft and reporters and photographers on the ground. Suspense, mounting by the minute, burst in a roar when the plane was spotted in the west. It flew steadily in, buzzed the field in a thunderous earth-shaking dive, swung around and settled smoothly on the long runway. Jake Harman and the crew of his Number 663 slid out of the silver belly to the enthusiastic greetings of the administrative, ground and maintenance men of Chikulia.”

42-6331 (Boeing serial number 3465) was a B-29-10-BW Superfortress which had been built at Boeing’s Wichita, Kansas, Plant II. It was delivered to the United States Army Air Forces 28 January 1944, and assigned to the 25th Bombardment Squadron (Very Heavy), 40th Bombardment Wing (Very Heavy), 58th Bombardment Wing (Very Heavy) at Pratt Army Air Field, Kansas.
After a number of combat missions, Gone With the Wind was modified to transport gasoline over the Himalaya Mountains to forward air bases in China.
On the night of 21 December 1944, Major Robert E. Moss, 45th Bombardment Squadron (Very Heavy), 40th Bombardment Group (Very Heavy), was flying Gone With The Wind near the port city of Chittagong, Burma. A Royal Air Force Bristol Beaufighter Mk VI D, E8710, flown by Squadron Leader R. R. Morrison, No. 89 Squadron, was vectored to intercept the bomber by ground controllers. Approaching from down moon, Morrison did not recognize the aircraft as an Allied B-29. He fired several bursts while closing from 700 to 500 feet (213 to 152 meters) and observed strikes along the center of the fuselage. The bomber’s fuel tanks caught fire. All 11 members of the bomber’s crew were able to escape, but the navigator, 1st Lieutenant David Lustig, was killed when his parachute did not open. 42-6331 crashed into the Bay of Bengal. The ten survivors were rescued. (MACR 10589)
Boeing B-29 Superfortress
The B-29 Superfortress was the most technologically advanced—and complex—aircraft of World War II. It required the manufacturing capabilities of the entire nation to produce. Over 1,400,000 engineering man-hours had been required to design the prototypes.
The Superfortress was manufactured by Boeing at Seattle and Renton, Washington, and Wichita, Kansas; by the Glenn L. Martin Company at Omaha, Nebraska; and by Bell Aircraft Corporation, Marietta, Georgia.

There were three XB-29 prototypes, 14 YB-29 pre-production test aircraft, 2,513 B-29 Superfortresses, 1,119 B-29A, and 311 B-29B aircraft. The bomber served during World War II and the Korean War and continued in active U.S. service until 1960. In addition to its primary mission as a long range heavy bomber, the Superfortress also served as a photographic reconnaissance airplane, designated F-13, a weather recon airplane (WB-29), and a tanker (KB-29).
The B-29 was operated by a crew of 11 to 13 men. It was 99 feet, 0 inches (30.175 meters) long with a wingspan of 141 feet, 3 inches (43.068 meters). The vertical fin was 27 feet, 9 inches (8.305 meters) high. The airplane’s empty weight was 71,500 pounds (32,432 kilograms). Its maximum takeoff weight of 140,000 pounds (63,503 kilograms).
The B-29’s wings had a total area of 1,720 square feet (159.8 square meters). They had an angle of incidence of 4° and 4° 29′ 23″ dihedral. The leading edges were swept aft to 7° 1′ 26″.

The B-29 was powered by four air-cooled, turbocharged and supercharged, 3,347.66-cubic-inch-displacement (54.858 liter) Wright Aeronautical Division Cyclone 18 (also known as the Duplex-Cyclone) 670C18BA4 (R-3350-23A) two-row, 18-cylinder radial engines with a compression ration of 6.85:1. These engines had a Normal Power rating of 2,000 horsepower at 2,400 r.p.m., and 2,200 horsepower at 2,800 r.p.m., for takeoff. They drove 16 foot, 7 inch (5.055 meter) diameter, four-bladed, Hamilton Standard constant-speed propellers through a 0.35:1 gear reduction. The R-3350-23A was 6 feet, 4.26 inches (1.937 meters) long, 4 feet, 7.78 inches (1.417 meters) in diameter and weighed 2,646 pounds (1,200 kilograms).
The maximum speed of the B-29 was 353 knots (406 miles per hour/654 kilometers per hour) at 30,000 feet (9,144 meters), though its normal cruising speed was 216 knots (249 miles per hour/400 kilometers per hour) at 25,000 feet (7,620 meters). The bomber’s service ceiling was 40,600 feet (12,375 meters) and the maximum ferry range was 4,492 nautical miles (5,169 statute miles/8,319 kilometers).

The Superfortress could carry a maximum of 20,000 pounds (9,072 kilograms) of bombs in two bomb bays. For defense, it was armed 12 Browning AN-M2 .50-caliber machine guns in four remotely-operated and computer-controlled gun turrets and a manned tail position. The bomber carried 500 rounds of ammunition per gun. (Some B-29s were also armed with an M2 20 mm autocannon at the tail.)

Leonard Franklin Harman was born at Auburn, Nebraska, 22 December 1902. He was the second of three children of William Bascomb Harman, an insurance agent, and Georgia Eva Horn Harman. The Harman family later moved to Boise, Idaho, where Leonard grew up. He attended Boise High School, graduating in 1921.
On 28 February 1928, Harman joined the U.S. Army Air Corps as a Flying Cadet. He was trained as a pilot at air fields in Texas. He graduated from the Air Corps Primary Flying School in 1928, and the Advanced Flying School’s Bombardment Course in 1929. Leonard Harman was commissioned a second lieutenant, Air Reserve, 28 February 1929. He was then assigned to active duty, 1 March–11 June 1929.
Harman received a commission as a second lieutenant, United States Army Air Corps, 2 May 1929.
In 1929, Lieutenant Harman married Miss Ruth Isabelle Veasey (1904–1999). They would have a daughter, Helen Jean Harman (1930– ).
Second Lieutenant Harman graduated from the Air Corps Engineering School in 1932. The following year, he received a Bachelor of Science Degree in Mechanical Engineering (BSME) from the University of Idaho.
From 19 July to 20 August 1934, Harman participated in the Air Corps’ Alaska Flight, in which ten Martin B-10 bombers under the command of Lieutenant Colonel Henry Harley (“Hap”) Arnold were flown from Bolling Field, Washington, D.C., to Fairbanks, Alaska. For the next month, numerous flights were made over Alaska, including photographing 23,000 square miles (59,570 square kilometers) of the territory. The trip crossed more than 7,000 miles (11,265 kilometers). (Arnold was awarded the Mackay Trophy for this operation. He later served in the five-star rank General of The Army and General of the Air Force.)

Harman was promoted to the rank of first lieutenant, 1 October 1934.
Lieutenant Harman was at Wright Field, northeast of Dayton, Ohio, on 30 October 1935 when the prototype Boeing XB-17 crashed after takeoff. With the B-17 on fire, Lieutenants Harman and Robert Kinnaird Giovannoli pulled survivors from the wreckage.

Both Harman and Giovannoli were awarded the Soldier’s Medal, the Army’s highest award for valor in a non-combat situation. “The Soldier’s Medal is awarded to any person of the Armed Forces of the United States or of a friendly foreign nation who, while serving in any capacity with the Army of the United States, including Reserve Component soldiers not serving in a duty status at the time of the heroic act, distinguished himself or herself by heroism not involving conflict with an enemy. The performance must have involved personal hazard or danger and the voluntary risk of life under conditions not involving conflict with an armed enemy. Awards will not be made solely on the basis of having saved a life.”
Lieutenant Harman’s citation reads: The President of the United States of America, authorized by Act of Congress, July 2, 1926, takes pleasure in presenting the Soldier’s Medal to First Lieutenant (Air Corps) Leonard F. Harman, United States Army Air Corps, for heroism, not involving actual conflict with an enemy, displayed at Wright Field, Dayton, Ohio, 30 October 1935. When a Boeing experimental bomber crashed and burst into flames, Lieutenant Harman forced his way upon the fuselage of the burning plane and assisted in the removal of the pilot and a passenger, despite the knowledge that his own life was in constant peril from fire, smoke, and fuel explosions. During the performance of the act, Lieutenant Harman suffered severe burns.
Harman had crawled into the XB-17’s cockpit and freed the feet of Major Ployer P. Hill, which were caught in the bomber’s rudder pedals. Both Harman and Giovannoli were treated at the base hospital for 1st and 2nd degree burns, then transferred to the Miami Valley Hospital. Harman was presented the Soldier’s Medal by Major General William E. Cole, Commanding General, Fifth Corps, United States Army, at Wright Field on 12 May 1936. (Lieutenant Giovannoli was killed in the crash of a Boeing P-26 at Logan Field, near Baltimore, Maryland, 8 March 1936, before he could be presented with his medal.)
In 1939, Harman attended the Air Corps Tactical School at Maxwell Field, Montgomery, Alabama. On 2 May 1939, he was promoted to the rank of captain.
Captain Harman was promoted to the temporary rank of major, U.S. Army Air Corps, 15 March 1941. On 10 October 1941, he was appointed a major in the Army of the United States (A.U.S.). Shortly after the United States entered World War II, on 5 January 1942, Harman was advanced to the temporary rank of lieutenant colonel, U.S. Army Air Forces, followed on 1 February 1942 by his promotion to lieutenant colonel, A.U.S. On 1 March 1942, he was promoted to colonel, A.U.S.
Throughout 1942 and 1943, Colonel Harman was very involved in the program to bring the Boeing B-29 Superfortress into production and active service in the War. On 27 November 1943, Colonel Harman was assigned Commander, 58th Bombardment Wing (Very Heavy) at Smoky Hill Army Air Field, Salina, Kansas.
On 15 June 1944, Colonel Harman lead 75 Twentieth Air Force B-29s on the first air raid against Japan since the Halsey-Doolittle Raid of 18 April 1942. The target was the Imperial Iron and Steel Works at Yawata, in northern Kyushu.

On 4 April 1945, Major General Kenneth Bonner Wolfe, who had met Colonel Harman when he arrived in India, 2 April 1944, presented him with the Distinguished Flying Cross for “a lone B-29 flight without fighter escort over enemy-occupied territory,” 7 July 1944.
Following the end of the War, on 2 May 1946 Harman reverted to his permanent Army Air Forces rank of major.
Having suffered a disability in the line of duty, on 30 November 1946, Harman retired from the U.S. Army Air Forces with the permanent rank of colonel.
During his military career, Colonel Harman had been awarded the Legion of Merit, the Distinguished Flying Cross and the Soldier’s Medal. He was rated a command pilot and command aerial observer.
Leonard Franklin Harman died at Laguna Hills, California, 2 March 1977, at the age of 74 years. After a memorial service held at MCAS El Toro, in southern California, his remains were cremated.

2 April 1942: After loading sixteen North American Aviation B-25B Mitchell medium bombers and their crews of the 17th Bombardment Group (Medium) at NAS Alameda, the recently commissioned United States Navy aircraft carrier USS Hornet (CV-8) departed San Francisco Bay with her escorts and headed for a secret rendezvous with Vice Admiral William F. Halsey, Jr., and Task Force 16.
The new carrier was under command of Captain Marc A. Mitscher. The strike group was commanded by Lieutenant Colonel James H. (“Jimmy”) Doolittle, U.S. Army Air Corps. Until the second day at sea, only six U.S. military officers knew of the mission.

USS Hornet was a brand new Yorktown-class aircraft carrier, commissioned 20 October 1941. It had just completed its shakedown cruise in the Atlantic when it was sent west for this mission.
The ship was 824 feet, 9 inches (251.384 meters) long, overall, with a maximum width of 114 feet (34.747 meters). Hornet‘s dimensions at the waterline (full load displacement) were 761 feet (232 meters) long with a beam of 83 feet, 3 inches (25.375 meters). Its draft was 28 feet (8.5 meters).
The flight deck had two hydraulic catapults, and three elevators for bringing aircraft up from the hangar deck. A third catapult was on the hangar deck, launching aircraft laterally.
Powered by four geared steam turbines driving four propeller shafts, Hornet‘s engines produced 120,000 shaft horsepower. The carrier’s maximum speed was 33.84 knots (39.94 miles per hour/62.67 kilometers per hour), and maximum range, 12,500 nautical miles (14,385 kilometers).

Higgins, U.S.N., commanding, closes on the carrier’s right rear quarter. The sixteen Army bombers used all the space available on Hornet’s flight deck.(U.S. Navy)
The aircraft carrier’s primary armament was its air wing, consisting of a squadron each of Grumman F4F Wildcat fighters, Douglas SBD Dauntless dive bombers and Douglas TBD Devastator torpedo bombers. For the Halsey-Doolittle Raid, Hornet‘s air wing was stored on the hangar deck and unavailable.
“To make room for the Army bombers, Hornet had struck her own planes below. Wildcats and Devastators, with wings folded, and dismantled SBDs were packed into every available space, even hung from the overhead. So, except for her few guns, the carrier was defenseless until she rendezvoused with Task Force 16. . . .”

For defense, the ship was lightly armored, with 2.5–4 inches (6.35–10.2 centimeters) of belt and deck armor. She also carried eight 5-inch, 38-caliber (5″/38) dual-purpose guns in single mounts, thirty 20mm Oerlikon autocannon, twenty water-cooled 1.1-inch, 75-caliber (1.1″/75) guns in four-gun mounts, and twenty-four Browning .50-caliber (12.7 millimeter) machine guns.
Including the ship’s air wing, the complement was 2,919 men.
USS Hornet fought at the Battle of Midway, June 3–7, 1942. She was sunk at the Battle of the Santa Cruz Islands, 26 October 1942, having been hit by two airplanes, 8 bombs, 16 torpedoes and an unknown number of 5-inch shells.¹
