17 May 1943: The flight crew of the B-17 Memphis Belle completed their combat tour of 25 bombing missions over Western Europe with an attack on the massive Kéroman Submarine Base at Lorient, France. ¹ The bomber was a U.S. Army Air Force Boeing B-17F-10-BO Flying Fortress, serial number 41-24485, assigned to the 324th Bombardment Squadron (Heavy), 91st Bombardment Group (Heavy), VIII Bomber Command, based at Air Force Station 121 (RAF Bassingbourne, Cambridgeshire, England). The aircraft commander was Captain Robert Knight Morgan, Air Corps, United States Army.

The daylight bombing campaign of Nazi-occupied Europe was extremely dangerous with high losses in both airmen and aircraft. For an American bomber crew, 25 combat missions was a complete tour, and then they were sent back to the United States for rest and retraining before going on to other assignments. Memphis Belle was only the second B-17 to survive 25 missions, ² so it was withdrawn from combat and sent back to the United States for a publicity tour.

The B-17′s name was a reference to Captain Morgan’s girlfriend, Miss Margaret Polk, who lived in Memphis, Tennessee. The artwork painted on the airplane’s nose was a “Petty Girl,” based on the work of pin-up artist George Petty of Esquire magazine. ³

(Morgan named his next airplane—a B-29 Superfortress—Dauntless Dotty, after his wife, Dorothy Grace Johnson Morgan. With it, he led the first B-29 bombing mission against Tokyo, Japan, in 1944. It was also decorated with a Petty Girl.)

Memphis Belle and her crew were the subject of a 45-minute documentary, “Memphis Belle: A Story of a Flying Fortress,” directed by William Wyler and released in April 1944. It was filmed in combat aboard Memphis Belle and several other B-17s. The United States Library of Congress named it for preservation as a culturally significant film.

B-17F-10-BO Flying Fortress 41-24485 (c/n 3190) was built by the Boeing Aircraft Company at its Plant 2 in Seattle, Washington, during the summer of 1942. It was the 195th airplane in the B-17F series, and one of the third production block. Flown by a Boeing pilot named Johnston, the new bomber made its first flight, 1 hour, 40 minutes, on 13 August 1942. Maintenance records indicate, “1st flight OK.”

The B-17 was flown to Bangor, Maine and on 31 August 1942 was assigned to the 324th Bombardment Squadron (Heavy), 91st Bombardment Group (Heavy), then preparing to deploy overseas.

2nd Lieutenant Morgan first flew 41-24485 on 3 September, and logged nearly 50 hours over the next three weeks. The squadron flew across the North Atlantic Ocean, and 41-24485 arrived at its permanent station, Bassingbourne, on 26 October 1942.

Following its twenty-fifth combat mission, Memphis Belle was flown back to the United States on 9 June 1943.

After the war, Memphis Belle was put on display in the city of Memphis. For decades it suffered from time, weather and neglect. The Air Force finally took the bomber back and placed it in the permanent collection of the National Museum of the United States Air Force at Wright-Patterson Air Force Base, Dayton, Ohio, where it underwent a total restoration.

The Boeing B-17F Flying Fortress was a four-engine heavy bomber operated by a flight crew of ten. It was 74 feet, 8.90 inches (22.781 meters) long with a wingspan of 103 feet, 9.375 inches (31.633 meters) and an overall height of 19 feet, 1.00 inch (5.187 meters). The wings have 3½° angle of incidence and 4½° dihedral. The leading edge is swept aft 8¾°. The total wing area is 1,426 square feet (132.48 square meters). The horizontal stabilizer has a span of 43 feet (13.106 meters) with 0° incidence and dihedral. Its total area, including elevators, is 331.1 square feet (12.18 square meters).

The B-17F had an approximate empty weight of 36,135 pounds (16,391 kilograms), 40,437 pounds (18,342 kilograms) basic, and the maximum takeoff weight was 65,000 pounds (29,484 kilograms).

The B-17F was powered by four air-cooled, supercharged, 1,823.129-cubic-inch-displacement (29.876 liters) Wright Cyclone G666A (R-1820-65) ⁴ nine-cylinder radial engines with a compression ratio of 6.70:1. The engines were equipped with remote General Electric  turbochargers capable of 24,000 r.p.m. The R-1820-65 was rated at 1,000 horsepower at 2,300 r.p.m. at Sea Level, and 1,200 horsepower at 2,500 r.p.m. for takeoff. The engine could produce 1,380 horsepower at War Emergency Power. 100-octane aviation gasoline was required. The Cyclones turned three-bladed, constant-speed, Hamilton-Standard Hydromatic propellers with a diameter of 11 feet, 7 inches (3.835 meters) through a 0.5625:1 gear reduction. The R-1820-65 engine is 3 feet, 11.59 inches (1.209 meters) long and 4 feet, 7.12 inches (1.400 meters) in diameter. It weighs 1,315 pounds (596 kilograms).

The B-17F had a cruising speed of 200 miles per hour (322 kilometers per hour). The maximum speed was 299 miles per hour (481 kilometers per hour) at 25,000 feet (7,620 meters), though with War Emergency Power, the bomber could reach 325 miles per hour (523 kilometers per hour) at 25,000 feet for short periods. The service ceiling was 37,500 feet (11,430 meters).

With a normal fuel load of 1,725 gallons (6,530 liters) the B-17F had a maximum range of 3,070 miles (4,941 kilometers). Two “Tokyo tanks” could be installed in the bomb bay, increasing capacity by 820 gallons (3,104 liters). Carrying a 6,000 pound (2,722 kilogram) bomb load, the range was 1,300 miles (2,092 kilometers).

The Memphis Belle was armed with 13 Browning AN-M2 .50-caliber machine guns for defense against enemy fighters. Power turrets mounting two guns each were located at the dorsal and ventral positions. Four machine guns were mounted in the nose, 1 in the radio compartment, 2 in the waist and 2 in the tail.

The maximum bomb load of the B-17F was 20,800 pounds (9434.7 kilograms) over very short ranges. Normally, 4,000–6,000 pounds (1,815–2,722 kilograms) of high explosive bombs were carried. The internal bomb bay could be loaded with a maximum of eight 1,600 pound (725.75 kilogram) bombs. Two external bomb racks mounted under the wings between the fuselage and the inboard engines could carry one 4,000 pound (1,814.4 kilogram) bomb, each, though this option was rarely used.

The B-17 Flying Fortress was in production from 1936 to 1945. 12,731 B-17s were built by Boeing, Douglas Aircraft Company and Lockheed-Vega. (The manufacturer codes -BO, -DL and -VE follows the Block Number in each airplane’s type designation.) 3,405 of the total were B-17Fs, with 2,000 built by Boeing, 605 by Douglas and 500 by Lockheed-Vega.

4 May 1967: Colonel Robin Olds, United States Air Force, commanding the 8th Tactical Fighter Wing based at Ubon RTAFB, shot down his second enemy airplane during the Vietnam War.

Colonel Olds had flown Lockheed P-38 Lightning and North American P-51 Mustang fighters during World War II. He is officially credited with shooting down 12 enemy airplanes over Europe and destroying 11.5 on the ground. On 2 January 1967, he had destroyed a MiG-21 near Hanoi, North Vietnam, while flying a McDonnell F-4C Phantom II. He was the first U.S. Air Force fighter ace to shoot down enemy aircraft during both World War II and the Vietnam War.

A description of the air battle follows:

On 4 May, the 8th TFW provided two flights of Phantoms for MiGCAP for five F-105 flights of the 355th TFW which were on a strike mission. Col. Olds, 8th Wing commander, led the rear flight, flying with 1st Lt. William D. Lafever. The other F-4 flight was sandwiched midway in the strike force. MiG warnings crackled on Olds’ radio just before his wingman sighted two MiG-21s at 11 o’clock, attacking the last of the Thunderchief flights. Colonel Olds’ account picks up the encounter at this point:

“The MiGs were at my 10 o’clock position and closing on Drill [the F-105 flight] from their 7:30 position. I broke the rear flight into the MiGs, called the F-105s to break, and maneuvered to obtain a missile firing position on one of the MiG-21s. I obtained a boresight lock-on, interlocks in, went full system, kept the pipper on the MiG, and fired two AIM-7s in a ripple. One AIM-7 went ballistic. The other guided but passed behind the MiG and did not detonate. Knowing I was too close for further AIM-7 firing, I maneuvered to obtain AIM-9 firing parameters. The MiG-21 was maneuvering violently and firing position was difficult to achieve. I snapped two AIM-9s at the MiG and did not observe either missile. The MiG then reversed and presented the best parameter yet. I achieved a loud growl, tracked, and fired one AIM-9. From the moment of launch it was obvious that the missile was locked on. It guided straight for the MiG and exploded about 5–10 feet beneath his tailpipe.

“The MiG then went into a series of frantic turns, some of them so violent that the aircraft snap-rolled in the opposite direction. Fire was coming from the tailpipe, but I was not sure whether it was normal afterburner or damage-induced. I fired the remaining AIM-9 at one point, but the shot was down toward the ground and did not discriminate. I followed the MiG as he turned southeast and headed for Phuc Yen. The aircraft ceased maneuvering and went in a straight slant for the airfield. I stayed 2,500 feet behind him and observed brilliant white fire streaming from the left side of his fuselage. It looked like magnesium burning with particles flaking off. I had to break off to the right as I neared Phuc Yen runway at about 2,000 feet, due to heavy, accurate, 85-mm barrage. I lost sight of the MiG at that point. Our number 3 saw the MiG continue in a straight gentle dive and impact approximately 100 yards south of the runway.”

Colonel Olds then took his flight to the target area and covered the last of the 355th TFW strike aircraft as they came off the target. Leading his flight to Hoa Lac airfield and dodging two SAMs on the way, he found five MiG-17s over that airfield.

“We went around with them at altitudes ranging from 1,500 to 6,000 feet, right over the aerodrome,” Olds reported. The F-4s ran low on fuel before any real engagements occurred, however, and were forced to break off the encounter.

SMITH, MAYNARD H. (Air Mission)

Rank and organization: Sergeant, U.S. Army Air Corps, 423d Bombardment Squadron, 306th Bomber Group.

Place and date: Over Europe, 1 May 1943.

Entered service at: Caro, Michigan.

Born: 1911, Caro Michigan.

G.O. No.: 38, 12 July 1943.

Medal of Honor
Medal of Honor

Citation: “For conspicuous gallantry and intrepidity in action above and beyond the call of duty. The aircraft of which Sgt. Smith was a gunner was subjected to intense enemy antiaircraft fire and determined fighter airplane attacks while returning from a mission over enemy-occupied continental Europe on 1 May 1943. The airplane was hit several times by antiaircraft fire and cannon shells of the fighter airplanes, 2 of the crew were seriously wounded, the aircraft’s oxygen system shot out, and several vital control cables severed when intense fires were ignited simultaneously in the radio compartment and waist sections. The situation became so acute that 3 of the crew bailed out into the comparative safety of the sea. Sgt. Smith, then on his first combat mission, elected to fight the fire by himself, administered first aid to the wounded tail gunner, manned the waist guns, and fought the intense flames alternately. The escaping oxygen fanned the fire to such intense heat that the ammunition in the radio compartment began to explode, the radio, gun mount, and camera were melted, and the compartment completely gutted. Sgt. Smith threw the exploding ammunition overboard, fought the fire until all the firefighting aids were exhausted, manned the workable guns until the enemy fighters were driven away, further administered first aid to his wounded comrade, and then by wrapping himself in protecting cloth, completely extinguished the fire by hand. This soldier’s gallantry in action, undaunted bravery, and loyalty to his aircraft and fellow crewmembers, without regard for his own personal safety, is an inspiration to the U.S. Armed Forces.”

Sergeant Smith was a ball turret gunner on a B-17 Flying Fortress on his first combat mission. The bomber was so badly damaged that, on landing, the airplane’s structure failed from battle damage and it broke in half. There were over 3,500 bullet and shrapnel holes.

Maynard Harrison Smith was born at Caro, Michigan, 19 May 1911. He was the second child of Henry Harrison Smith, a lawyer, and Mary Christine Gohs Smith, a school teacher.

Smith worked as a clerk in a government insurance office. He married Miss Arlene E. McCreedy at Ferndale, Michigan, 31 July 1929. They had a daughter, Barbara Lou Smith. They divorced 22 October 1932. He later married his second wife, Helene Gene Gunsell, at Caro, Michigan, 30 March 1941.

Maynard Smith enlisted in the U.S. Army Air Corps, 31 August 1941. He was trained as an aerial gunner, and on completion, was promoted to the rank of staff sergeant. He was assigned as a ball turret gunner in a B-17 combat crew of the 423rd Bombardment Squadron (Heavy), 306th Bombardment Group (Heavy), based at RAF Thurleigh, Bedfordshire, England.

A gunner fires the two Browning .50 caliber machine guns of his electrically-powered Sperry ball turret.

Following the 1 May mission, Staff Sergeant Smith flew only four more combat missions before a medical board diagnosed him with Operational Exhaustion. He was removed from flight status and reverted to his initial rank of private.

While stationed in England, Sergeant Smith met Miss Mary Rayner, a British subject and USO volunteer. They were married in 1944. They would have four children.

Sergeant Smith was released from active duty, 26 May 1945.

Following World War II, Smith worked for the Department of the Treasury. He later founded Police Officers Journal, a magazine oriented toward law enforcement officers.

Based on an examination of certain facts in his life, as well as anecdotes by persons who knew him, it is fair to say the Maynard Smith was a troubled individual. But the extreme courage he displayed on 1 May 1943 cannot be denied.

Maynard Smith died at St. Petersburg, Florida, 11 May 1984 at the age of 72 years. He was buried at Arlington National Cemetery.

Staff Sergeant Maynard Harrison Smith, United States Army Air Forces, was the first of only five Air Force enlisted airmen to be awarded the Medal of Honor during World War II. He was also awarded the Air Medal, with one oak leaf cluster (two awards).

Boeing B-17F-65-BO Flying Fortress 42-29649 was delivered to Denver, Colorado, 29 January, 1943. After crossing the North Atlantic Ocean, the new bomber was assigned to the 423rd Bombardment Squadron (Heavy), 306th Bombardment Group (Heavy) at RAF Thurleigh, near Bedford, Bedfordshire, England, 24 March 1943. It was identified by the letters RD-V painted on its fuselage.

On 1 May 1943, 42-29649 was one of 18 B-17s of the 306th Bombardment Group assigned to attack German Kriegsmarine submarine pens at Saint-Nazaire, on the Atlantic coast of France. Another 60 B-17s from three other groups were also part of the mission. Only 12 bombers from the 306th arrived over the target, which was heavily obscured by clouds. Each bomber carried two 2,000-pound (907 kilogram) General Purpose bombs, which were dropped from 25,200 feet (7,681 meters) on a heading of 270°. After a 20-second bomb run, the group released its bombs at 11:26 a.m.

Flying away from the target area, the 306th flew over the city of Brest at low altitude. 42-29649 was hit by anti-aircraft fire. The group was then attacked by 15–20 Luftwaffe Focke-Wulf Fw 190 fighters. Two bombers were shot down over the city and a third ditched near the coast. -649 caught fire and three crewmen bailed out over the water and were lost.

Of the 78 B-17s dispatched, 7 were lost. 73 crewmembers were listed as Missing in Action, 18 Wounded in Action and 2 Killed in Action.

On 1 May 1943, 42-29649 was flown by Captain Lewis P. Johnson, Jr., aircraft commander/pilot; 1st Lieutenant Robert McCallum, co-pilot; 1st Lieutenant Stanley N. Kisseberth, navigator; Staff Sergeant J.C. Melaun, nose gunner and bombardier; Technical Sergeant William W. Fahrenhold, flight engineer/top turret gunner; Staff Sergeant Maynard H. Smith, ball turret gunner; Technical Sergeant Henry R. Bean, radio operator; Staff Sergeant Robert V. Folliard, waist gunner; Staff Sergeant Joseph S. Bukacek, waist gunner; Sergeant Roy H. Gibson, tail gunner. Sergeants Bean, Folliard and Bukacek were killed in action.

This Boeing B-17F-55-BO Flying Fortress, 42-29524. also o fthe 423rd Bombardment Squadron, was very similar to teh one on which Sergeant Smith was the ball turret gunner. The squadron identification markings, "RD", are painted on the fuselage. The second letter "D" identifies this particular airplane. (U.S> Air Force)

The Nieuport 28 C.1 ¹ was a single-place, single-engine, single-bay biplane fighter built by Société Anonyme des Éstablissements Nieuport for the French military. It was rejected, however, in favor of the SPAD S.XIII C.1. The new United States’ Air Service was in great need of fighters. There were none available of American manufacture, and because the new SPAD was in great demand, 297 Nieuport 28s were acquired by the American Expeditionary Force and assigned to the 94th and 95th Aero Squadrons.

The Nieuport 28 C.1 was 6.30 meters (20 feet, 8 inches) long with an upper wingspan of 8.160 meters (26 feet, 9¼ inches), lower wingspan of 7.79 meters ( 25 feet, 6-2/3 inches)  and height of 2.30 meters (7 feet, 6½ inches). The upper wing had a chord of 1.30 meters (4 feet, 3.2 inches), and the lower, which was staggered behind the upper, had a chord of 1.00 meters (3 feet, 3.4). The upper wing had very slight dihedral, while the lower wing had none. Its empty weight was 399 kilograms (880 pounds) and loaded weight was 626 kilograms (1,380 pounds).

Nieuport 28 C.1, serial number 6215.

The Nieuport 28 C.1 was powered by an air-cooled, normally-aspirated 15.892 liter (969.786-cubic-inch-displacement) Gnome Monosoupape 9 Type N nine-cylinder rotary engine with a compression ratio of 5.45:1. The Monosoupape had a single overhead exhaust valve actuated by a pushrod and rocker arm. As the pistons reached the bottom of their exhaust strokes, a series of intake ports near the bottom of the cylinder were uncovered. The intake charge was drawn from the engine crankcase. The Type N produced 160 horsepower at 1,300 r.p.m. and turned a two-bladed fixed-pitch wooden propeller with a diameter of 2.50 meters (8 feet, 2.4 inches). The engine weighed 330 pounds (150 kilograms).

The Nieuport 28 had a top speed of 198 kilometers per hour (123 miles per hour) at 2,000 meters (6,562 feet) and 1,380 r.p.m., a range of 290 kilometers (180 miles) and a service ceiling of 5,300 meters (17,388 feet). Duration at full power was 1 hour, 45 minutes.

Two .303-caliber Vickers machine guns were mounted on the cowling, firing forward through the propeller arc.

Pfalz D.III (SDASM)

The Pfalz D.III was a single-seat, single-engine, single-bay biplane fighter built by Pfalz Flugzeugwerke. The fuselage was built of two layers of plywood strips laid over a mold to form one half. The two halves were glued together. This was then covered with doped fabric. The wings were made of fabric-covered wood spars and ribs, with wooden ailerons.

It was 6.95 meters (22 feet, 9½ inches) long with a wingspan of 9.4 meters (30 feet, 0 inches) and height of 2.67 meters (8 feet, 9 inches). Empty weight was 695 kilograms (1,532 pounds) and gross weight was 933 kilograms (2,057 pounds).

The fighter was powered by a 14.778 liter (901.812 cubic inches) water-cooled Mercedes D.IIIa single overhead cam inline six-cylinder engine with two valves per cylinder and a compression ratio of 4.64:1. It produced 174 horsepower at 1,400 r.p.m. The D.IIIa weighed 660.0 pounds (299.4 kilograms).

The maximum speed of the Pfalz D.III was 185 kilometers per hour (115 miles per hour) at Sea Level, and the service ceiling was 5,200 meters (17,060 feet).

It was armed with two 7.92 mm LMG 08/15 Spandau machine guns.
