25 April 1956: At Edwards Air Force Base, California, test pilot Lieutenant Colonel Frank Kendall (“Pete”) Everest, United States Air Force, was airdropped from a Boeing EB-50D Superfortress in the Bell X-2 supersonic research rocket plane, serial number 46-674. This was the tenth flight of the X-2 program, and only the third powered flight.

For the first time, Everest fired both chambers of the Curtiss-Wright XLR25 rocket engine. On this flight, the X-2 reached Mach 1.40 and 50,000 feet (15,240 meters). It was the first time an X-2 had gone supersonic.

The X-2 was a joint project of the U.S. Air Force and NACA (the National Advisory Committee on Aeronautics, the predecessor of NASA). The rocketplane was designed and built by Bell Aircraft Corporation of Buffalo, New York, to explore supersonic flight at speeds beyond the capabilities of the earlier Bell X-1 and Douglas D-558-II Skyrocket.

In addition to the aerodynamic effects of speeds in the Mach 2.0–Mach 3.0 range, engineers knew that the high temperatures created by aerodynamic friction would be a problem, so the aircraft was built from stainless steel and K-Monel, a copper-nickel alloy.

The Bell Aircraft Corporation X-2 was 37 feet, 10 inches (11.532 meters) long with a wingspan of 32 feet, 3 inches (9.830 meters) and height of 11 feet, 10 inches (3.607 meters). Its empty weight was 12,375 pounds (5,613 kilograms) and loaded weight was 24,910 pounds (11,299 kilograms).

The X-2 was powered by a throttleable two-chamber Curtiss-Wright XLR25-CW-1 rocket engine that produced 2,500–15,000 pounds of thrust (11.12–66.72 kilonewtons).

Rather than use its limited fuel capacity to take off and climb to altitude, the X-2 was dropped from a modified heavy bomber as had been the earlier rocketplanes. A four-engine Boeing B-50D-95-BO Superfortress bomber, serial number 48-096, was modified as the drop ship and redesignated EB-50D.

The launch altitude was 30,000 feet (9,144 meters). After the fuel was exhausted, the X-2 glided to a touchdown on Rogers Dry Lake at Edwards Air Force Base.

Two X-2 rocketplanes were built. The second X-2, 46-675, was destroyed during a captive flight, 12 May 1953. The explosion killed Bell test pilot Skip Ziegler and Frank Wolko, an engineer aboard the B-50A mothership. The B-50 made an emergency landing but was so badly damaged that it never flew again.

The X-2 reached a maximum speed of Mach 3.196 (2,094 miles per hour/3,370 kilometers per hour) and maximum altitude of 126,200 feet (38,466 meters).

The EB-50D was a highly modified four-engine Boeing B-50D-95-BO Superfortress long range heavy bomber, engineered to carry research aircraft to high altitudes before releasing them for a test flight. The B-50 was an improved version of the World War II B-29A Superfortress.

Frank Kendall (“Pete”) Everest, Jr., was born 10 Aug 1920, at Fairmont, Marion County, West Virginia. He was the first of two children of Frank Kendall Everest, an electrical contractor, and Phyllis Gail Walker Everest. Attended Fairmont Senior High School, Fairmont, West Virginia, graduating in 1939. He studied at Fairmont State Teachers College, also in Fairmont, West Virginia, and then studied engineering at teh University of Wesst Virginia in Morgantown.

Pete Everest enlisted as an aviation cadet in the United States Army Air Corps at Fort Hayes, Columbus, Ohio, 7 November 1941, shortly before the United States entered World War II. His enlistment records indicate that he was 5 feet, 7 inches (1.703 meters) tall and weighed 132 pounds (59.9 kilograms). He graduated from pilot training and was commissioned as a second lieutenant, Air Reserve, 3 July 1942.

Everest married Miss Avis June Mason in Marion, West Virginia, in 1942.

He was promoted to 1st Lieutenant, Army of the United States, 11 November 1942. He was assigned as a Curtiss-Wright P-40 Warhawk pilot, flying 94 combat missions in North Africa, Sicily and Italy. He was credited with shooting down two German airplanes and damaging a third. Everest was promoted to the rank of Captain, 17 August 1943.

In 1944, Everest was returned to the United States to serve as a flight instructor. He requested a return to combat and was then sent to the China-Burma-India theater of operations where he flew 67 missions and shot down four Japanese airplanes. He was himself shot down by ground fire in May 1945. Everest was captured by the Japanese and suffered torture and inhumane conditions before being freed at the end of the war. He was promoted to the rank of major, 1 July 1945. He was returned to the United States military 3 October 1945.

After the war, Everest was assigned as a test pilot at Wright-Patterson Air Force Base, Ohio, before going west to the Air Force Flight Test Center at Edwards Air Force Base, California.

Everest was returned to the permanent rank of first lieutenant, Air Corps, 19 June 1947, with date of rank retroactive to 3 July 1945.

Medal of Honor

Citation: First Lieutenant Raymond L. Knight on 24 and 25 April 1945 in the northern Po Valley, Italy, piloted a fighter-bomber aircraft in a series of low-level strafing missions, destroying 14 grounded enemy aircraft and leading attacks which wrecked 10 others during a critical period of the Allied drive in northern Italy. On the morning of 24 April, he volunteered to lead two other aircraft against the strongly defended enemy airdrome at Ghedi. Ordering his fellow pilots to remain aloft, he skimmed the ground through a deadly curtain of antiaircraft fire to reconnoiter the field, locating eight German aircraft hidden beneath heavy camouflage. He rejoined his flight, briefed them by radio, and then led them with consummate skill through the hail of enemy fire in a low-level attack, destroying five aircraft, while his flight accounted for two others. Returning to his base, he volunteered to lead three other aircraft in reconnaissance of Bergamo Airfield, an enemy base near Ghedi and one known to be equally well defended. Again ordering his flight to remain out of range of antiaircraft fire, Lieutenant Knight flew through an exceptionally intense barrage, which heavily damaged his Thunderbolt, to observe the field at minimum altitude. He discovered a squadron of enemy aircraft under heavy camouflage and led his flight to the assault. Returning alone after this strafing, he made 10 deliberate passes against the field despite being hit twice more by antiaircraft fire, destroying six fully loaded enemy twin-engine aircraft and two fighters. His skillfully led attack enabled his flight to destroy four other twin-engine aircraft and a fighter airplane. He then returned to his base in his seriously damaged airplane. Early the next morning, when he again attacked Bergamo, he sighted an enemy plane on the runway. Again he led three other American pilots in a blistering low-level sweep through vicious antiaircraft fire that damaged his airplane so severely that it was virtually nonflyable. Three of the few remaining enemy twin-engine aircraft at that base were destroyed. Realizing the critical need for aircraft in his unit, he declined to parachute to safety over friendly territory and unhesitatingly attempted to return his shattered airplane to his home field. With great skill and strength, he flew homeward until caught by treacherous air conditions in the Apennine Mountains, where he crashed and was killed. The gallant action of Lieutenant Knight eliminated the German aircraft which were poised to wreak havoc on Allied forces pressing to establish the first firm bridgehead across the Po River. His fearless daring and voluntary self-sacrifice averted possible heavy casualties among ground forces and the resultant slowing of the drive which culminated in the collapse of German resistance in Italy.

Raymond Larry Knight was born 15 June 1922 in Houston, Texas. He was the third child of John Franklin Knight, a clerk, and Sarah Francis Kelly Knight. He attended John H. Reagan Senior High School in Houston, graduating in 1940.

Knight married Miss Johnnie Lee Kinchloe, also a 1940 graduate of Reagan High School, 5 June 1942. They had one son, Raymond Jr.

Knight enlisted as an aviation cadet in the United States Army Air Corps, 10 Oct 1942, and trained as a fighter pilot at various airfields in Texas. He graduated from flight school and was commissioned as a second lieutenant, May 1944. After advanced training, Knight was assigned to the 346th Fighter Squadron, 350th Fighter Group, 12th Air Force, at Tarquinia Airfield, Italy, in November 1944. He was promoted to first lieutenant in March 1945.

Lieutenant Knight flew 82 combat missions. He is credited with 14 enemy aircraft destroyed.

The Medal of Honor was presented to Mrs. Knight by Major General James Pratt Hodges at a ceremony at John H. Reagan Senior High School, 23 October 1945.

In addition to the Medal of Honor, Lieutenant Knight was also awarded the Distinguished Flying Cross, and the Air Medal with five oak leaf clusters (six awards).

The remains of 1st Lieutenant Raymond Larry Knight, United States Army Air Corps, are interred at the Houston National Cemetery, Houston, Texas.

The Republic P-47 Thunderbolt was the largest single-engine fighter that had yet been built. The first P-47D variant was very similar to the preceding P-47C. The Thunderbolt which Raymond Knight flew on his final mission was a P-47D-27-RE, serial number 42-26785. He had named it OH JOHNNIE after his wife. The Thunderbolt’s bubble canopy had been introduced with the Block 25 series, and Block 27 added a dorsal fillet to improve longitudinal stability which had been diminished with the new aft fuselage configuration.

The P-47D-27-RE was 36 feet, 1¾ inches (11.017 meters) long with a wingspan of 40 feet, 9-3/8 inches (12.430 meters) The overall height was 14 feet, 7 inches (4.445 meters). The fighter’s empty weight was 10,700 pounds (4,853 kilograms) and maximum gross weight was 17,500 pounds (7,938 kilograms).

The P-47D-27-RE was powered by an air-cooled, supercharged and turbocharged 2,804.4-cubic-inch-displacement (45.956 liter) Pratt & Whitney Double Wasp TSB1-G (R-2800-59) two-row, 18-cylinder radial engine with a compression ratio of 6.65:1. The R-2800-59 had a Normal Power rating of 1,625 horsepower at 2,550 r.p.m. to 25,000 feet (7,620 meters) and a Takeoff/Military Power rating of  2,000 horsepower at 2,700 r.p.m. to an altitude of 25,000 feet (7,620 meters).¹ A large General Electric turbosupercharger was mounted in the rear of the fuselage. Internal ducts carried exhaust gases from the engine to drive the turbocharger. This supercharged air was then carried forward through an intercooler and then on to the carburetor to supply the engine. The engine’s mechanical supercharger further pressurized the air-fuel charge. The engine drove a 13 foot, 0 inch (3.962 meter) diameter four-bladed Curtiss Electric or Hamilton Standard Hydromatic propeller through a 2:1 gear reduction. The R-2800-59 was 6 feet, 3.72 inches (1.923 meters) long, 4 feet, 4.50 inches (1.340 meters) in diameter, and weighed 2,290 pounds (1,039 kilograms).

The P-47D had a maximum speed in level flight of 444 miles per hour (715 kilometers per hour) at 23,200 feet (7,071 meters) with 70 inches Hg manifold pressure (2.37 Bar), using water injection. The service ceiling was 40,000 feet (12,192 meters). It had a maximum range of 950 miles (1,529 kilometers) with internal fuel, and 1,800 miles (2,897 kilometers) with external tanks.

The Thunderbolt was armed with eight Browning AN-M2 .50-caliber machine guns, four in each wing, with 3,400 rounds of ammunition. It could also carry external fuel tanks, rockets and bombs. The structure of the P-47 could be described as “robust” and it was heavily armored. The amount of damage that the airplane could absorb and still return was remarkable.

A total of 15,683 Thunderbolts were built; more than any other Allied fighter type. In aerial combat, it had a kill-to-loss ratio of 4.6:1. The P-47, though, really made its name as a ground attack fighter, destroying aircraft, locomotives, rail cars, and tanks by the many thousands. It was one of the most successful aircraft of World War II.

21 April 1944: The first military helicopter combat rescue began with Lieutenant Carter Harman, 1st Air Commando Group, being ordered to proceed from Lalaghat, India with his Vought-Sikorsky YR-4B, 43-28247, 600 miles (965 kilometers) to Taro in northern Burma.

Technical Sergeant Ed “Murphy” Hladovcak, pilot of a Stinson L-1A Vigilant liaison airplane, had crashed in the jungle behind Japanese lines while transporting three wounded British soldiers. Lieutenant Harman was assigned to attempt to rescue the four men. It would be a marathon operation.

It took Harman and his Sikorsky 24 hours to arrive at Taro. After a brief rest and dip in the river to cool off, he continued for another 125 miles (202 kilometers) to an airstrip in the jungle called “Aberdeen” which was well behind the enemy lines. It was from here that Sgt. Hladovcak had been operating, flying out wounded soldiers. From Aberdeen, Harman was led to the location of the downed men by another liaison airplane. The survivors were surrounded by Japanese soldiers who had found the crashed airplane and were trying to locate the four men.

Because of the high heat, elevation and humidity, which increased the density altitude, the YR-4B’s air-cooled engine was unable to produce its full rated power. Also, the helicopter’s rotor blades were not as effective as they would have beeen at lower density altitudes.

Harman planned to lift one of the survivors out of the clearing in the jungle and fly a short distance to a sand bank where other L-1 or L-5 liaison airplanes could pick them up and fly them back to Aberdeen. He would repeat the operation until all four men had been rescued. However, it took the rest of the day to airlift just the first two wounded and very sick soldiers.

Distinguished Flying Cross

On the second flight, the helicopter’s engine was overheating and on landing it seized and could not be restarted. Sergeant Hladovcak and the remaining soldier were still in the jungle, Lieutenant Harman was stuck by the river bank and Japanese soldiers were everywhere.

On the morning of 25 April Lieutenant Harman was able to get the helicopter’s engine to start, and again, one at a time, he rescued the two remaining survivors. A liaison plane flew out the wounded soldier while Hladovcak rode along with Harman back to Aberdeen. He had never seen a helicopter before.

For his actions, Lieutenant Carter Harman was awarded the Distinguished Flying Cross.

Sikorsky YR-4B 43-28247 was condemned 31 December 1944.

The Sikorsky YR-4B was a two-place, single-engine helicopter with a single main rotor and an anti-torque tail rotor. The fuselage was 35 feet, 8.375 inches (10.881 meters) long with a main rotor diameter of 38 feet, 0 inches (11.582 meters). The tail rotor was 8 feet, 2.25 inches (2.496 meters) in diameter. Its overall length, with rotors turning, was 48 feet, 3.375 inches (4.716 meters). The helicopter had an overall height of 12 feet, 5 inches (3.785 meters). The empty weight was 2,020 pounds (916 kilograms) and maximum takeoff weight of 2,540 pounds (1,152 kilograms). The helicopter’s fuel capacity was 30 gallons (113.6 liters)

The main rotor consisted of three tapered, fully-articulated blades built of chrome-molybdenum steel spars and spruce plywood ribs, with laminated spruce, balsa and mahogany forming the leading edge and a flexible cable forming the trailing edge. The blades were covered with two layers of doped fabric. The three-bladed semi-articulated tail rotor was built with a spruce spar and alternating laminations of maple and mahogany, covered with fabric. Both the main and tail rotors had a thin brass abrasion strip covering the leading edges. The main rotor turned counter-clockwise, as seen from above. (The advancing blade is on the helicopter’s right.) The tail rotor was mounted on the helicopter’s right side in a tractor configuration. It turned clockwise as seen from the helicopter’s left. (The advancing blade is below the axis of rotation.)

The YR-4B was powered by an air-cooled, direct-drive 555.298-cubic-inch-displacement (9.100 liter) Warner Super Scarab SS185 (R-550-3) seven-cylinder radial engine with a compression ratio of 6.20:1. The R-550-3 was rated at 185 horsepower at 2,175 r.p.m. at Sea Level, and 200 horsepower at 2,475 r.p.m (five minute limit) for takeoff. The engine was placed backwards in the aircraft with the propeller shaft driving a short driveshaft through a clutch to a 90° gear box and the transmission. The R-550-3 weighed 344 pounds (156 kilograms).

The R-4B had a cruise speed of 65 miles per hour (105 kilometers per hour) and maximum speed of 82 miles per hour (132 kilometers per hour). The service ceiling was 12,000 feet (3,658 meters) and range was 157 miles (253 kilometers).

The YR-4B was equipped with bomb racks. It could carry three 125 pound (56.7 kilogram) demolition bombs or one 325 pound (147 kilogram) depth bomb. The equipment was deleted for the R-4B.

Sikorsky built 27 YR-4Bs and 100 R-4B helicopters. Of these, 40 were assigned to the Army Air Corps, 19 to the Navy and Coast Guard, and 41 were sent to the Royal Air Force and Royal Navy.

Carter Harman was born at Brooklyn, New York, 14 June 1918, the son of Steven Palmer Harman, a newspaper editor, and Helen F. Doremus Harman.

Before the war, Harman had been a musician and author. He assisted Duke Ellington write an autobiography. Harman earned a bachelor’s degree in music composition from Princeton University, Princeton, New Jersey, in 1940. While at Princeton, Harman was a member of the Dial Lodge, American Whig Society, Princeton University Band, and the Princeton University Choir.

Harman enlisted as a private in the United States Army at Hew York City on 1 April 1942, and was assigned to the Air Corps. Enlistment records indicate that he was 5 feet, 7 inches (170.2 centimeters) tall and weighed 125 pounds (57 kilograms).

After World War II ended, Harman returned to his musical studies at Columbia University, New York City, receiving a master’s degree in 1949.

Harman worked as a music critic for The New York Times and Time Magazine, and also continued writing books, as well as composing for ballet and opera. He was also a music producer and became executive vice president of CRI Records (Composers Recordings, Inc.).

Harman was married three times. He married Miss Nancy Hallinan, 5 February 1946, however they later divorced. His second wife was Helen Scott. They had four children together. His third wife was Wanda Maximilien.

Carter Harman died at Berlin, Vermont, 23 January 2007 at the age of 88 years.

The Hubble Space Telescope is named after Edwin Hubble, an early 20th century astronomer who discovered galaxies beyond our own Milky Way galaxy. It is an optical Ritchey–Chrétien telescope (an improved Cassegrain reflector). Star light enters the telescope and is collected by a large 7 foot, 10.5 inch (2.400 meter) diameter hyperbolic mirror at the back end. The light is reflected forward to a smaller hyperbolic mirror, which focuses the light and projects it back through an opening in the main reflector. The light is then gathered by the electronic sensors of the space telescope. These mirrors are among the most precise objects ever made, having been polished to an accuracy of 10 nanometers.

23–24 April 1967

23–24 April 1967: At 00:35:00 UTC, 23 April, Soyuz-1, the first manned flight of the Soyuz 7K-OK spacecraft, was launched from Baikonur Cosmodrome Pad 1/5 (Gagarin’s Start). On this first test flight, only one person was aboard the craft, which had been designed to carry three cosmonauts. Colonel Vladimir Mikhailovich Komarov was the pilot. He had previously flown Voskhod-1, a 24-hour mission, in 1964.

The mission plan called for a second spacecraft, Soyuz-2, to be launched on the 24th, with a three-man crew. A rendezvous in orbit would be made.

Soyuz-1 was not ready to be flown. More than 200 faults were known, but the pressures brought about by politics required that the launch proceed.

On reaching orbit, two solar arrays were to deploy to provide electrical power for the spacecraft’s batteries. One panel did not deploy and this severely limited the power available.

The Soyuz stabilization system relied on sensors which would detect certain stars to provide orientation, but the failed solar panel covered them. Within a few orbits the system failed completely. Komarov used the ship’s thrusters to manually control stability, but this was only marginally effective.

There were also communications difficulties. With electrical power diminishing and reaction fuel being spent, the main goals of the mission could no longer be achieved. After 13 orbits it was decided to abort the mission.

Komarov had to manually align the Soyuz-1 during the daylight phase of orbit 18. Gyroscopic stabilizers were supposed to maintain that alignment as the spacecraft passed into darkness. Komarov would once again align the craft when it came around into light, and hold that alignment through the reentry deceleration.

For some reason, the braking engine was 2 minutes, 23.5 seconds late in firing. The deceleration burn was planned for 2 minutes, 30 seconds, but an automatic system, recognizing that the gyro system was not holding the proper alignment, cut off the engine 4 seconds early. This meant that the Soyuz would travel farther down range than intended, and would not have slowed quite as much, although it was enough for re-entry.

Soyuz-1 impacted the Earth at 03:22:52 UTC, 1.9 miles (3.06 kilometers) to the west of Karabutak, Orenburg Oblast, at speeds estimated at from 30–40 meters per second (67–89 miles per hour) to as high as 640 kilometers per hour (398 miles per hour). It is believed that Vladimir Komarov died from injuries sustained at this time.

He was the first person to die during a space flight.

A rescue helicopter quickly located the Soyuz reentry module which was lying on its side in an open field with its parachute alongside. The rescuers reportedly saw the soft-landing rockets fire, which they should have done just before the module’s impact.

The module was on fire and by the time rescuers reached it, it was fully involved and molten metal was spreading on the ground. After expending their fire extinguishers, the rescuers tried to put of the fire by shoveling dirt on to it, but the the capsule completely collapsed.

Doctors on the scene pronounced Vladamir Komarov dead, with injuries to his skull, spinal cord, and numerous broken bones resulting from the impact. His body was completely burned. A postmortem examination at Moscow confirmed that the cosmonaut had been killed by the capsule’s impact.

Several theories have been published as explanation for the failure of the spacecraft’s parachute to safely slow Komarov’s descent, though with the craft completely destroyed by fire, it is unlikely that there could be any certainty. The official finding is that the drogue parachute did not apply enough force to pull the main parachute free. A backup parachute was deployed manually by Komarov but it fouled in the drogue ‘chute and did not open sufficiently to brake the craft.

Another theory is that a pressure sensor malfunctioned which prevented the automatic deployment of the main parachute. The drogue ‘chute should have been released at that time, but was not, which resulted in the reserve parachute fouling.

Third is that during an autoclaving operation the parachutes may have been contaminated with an adhesive substance.

And another story is this: During the design of Soyuz-1, the thickness of the heat shield was increased, and so the weight of the spacecraft went up. Engineers increased the size of the main parachute accordingly. But the compartment that it was to be stored in remained the same size. The fit was so tight that when the parachute was being installed, technicians had to hammer it into place with wooden mallets.

Vladimir Mikhailovich Komarov was born at Moscow, Russian Socialist Federated Soviet Republic (RSFSR), 16 March 1927. His father was killed early in The Great Patriotic War (World War II). At the age of 15 years, Vladimir Mikhailovich entered the 1st Moscow Special Air Force School and graduated in 1945. He then went to Sasovskoye for initial pilot training, and then to the Borisoglebsk Air Force Pilot School. In 1946 he was transferred to the A.K. Serov Bataisk Military Aviation School. He received his pilot’s wings and was commissioned as a lieutenant in the Soviet Air Force, 10 December 1949.

Lieutenant Komarov served as a fighter pilot of the 383rd Fighter Aviation Regiment at Grozny. The regiment was transitioning from the Mikoyan-Guervich MiG-9 turbojet-powered fighter to the new swept-wing MiG-15. While there, he met his future wife, Valentina Yakovlevna Kiselyova, a recent graduate of the Grozny Teachers’ Training Institute. They were married in 1950. They had two children, Yevgeny and Irina.

In 1952, Senior Lieutenant Komarov was assigned as senior pilot of the 486th Fighter Aviation Regiment, flying the MiG-15 and MiG-17. In 1954 he applied to attend the N.E. Zhukovsky Air Force Engineering Academy, from which he graduated in 1959. Promoted to Senior Lieutenant-Engineer, he was assigned as a test pilot at the Central Scientific Research Institute.

After promotion to captain-engineer, 3 September 1960, Komarov was selected for the first group of Soviet cosmonauts. He was older than most of the group, but was well liked and respected.

Colonel-Engineer Vladimir Mihailovich Komarov, Pilot-Cosmonaut of the USSR, was twice named Hero of the Soviet Union. He had also been awarded the Order of Lenin, Order of the Red Star, as well as several other decorations.

Following a state funeral, the cosmonaut’s ashes were interred in the Kremlin Wall at Red Square.
