25 March 1955: Chance Vought Aircraft Corporation experimental test pilot John William Konrad took the first prototype XF8U-1 Crusader, Bu. No. 138899, for its first flight at Edwards Air Force Base in the high desert of Southern California.

The new fighter had been transported from the factory at Dallas, Texas, aboard a Douglas C-124C Globemaster II, on 3 March 1955. It was reassembled and all systems were checked. Taxi tests began on 14 March.

During the first flight on 25 March, the Crusader went supersonic in level flight. It was able to maintain supersonic speeds (not only for short periods in a dive) and was the first fighter aircraft to exceed 1,000 miles per hour in level flight (1,609 kilometers per hour).

The F8U Crusader has a unique variable-incidence wing which can be raised to increase the angle of attack. This created more lift at low speeds for takeoff and landing aboard aircraft carriers, but allows the fuselage to remain fairly level for better forward visibility.

The test program went so well that the first production airplane, F8U-1 Crusader Bu. No. 140444, made its first flight just over six months after the prototype’s.

The Chance Vought F8U-1 was nearly identical to the prototype XF8U-1. It was a single-place, single-engine swept-wing fighter designed to operate from the United States Navy’s aircraft carriers. The F8U-1 was 54 feet, 2.75 inches (16.529 meters) long with a wingspan of 35 feet, 8 inches (10.871 meters) and height of 15 feet, 9.1 inches (4.803 meters). With wings folded, the airplane’s width was reduced to 22 feet, 6 inches (6.858 meters).

The Crusader’s wing angle of incidence was adjustable in flight. It had a total area of 375 square feet (34.8 square meters). The leading edges were swept aft to 47°, and the outer panels had a 1 foot, 0.7 inch “dog tooth.” The wings had 5° anhedral, while the horizontal stabilator had 5° 25′ dihedral. The stabilator’s leading edges were swept 50°.

Its empty weight was 15,513 pounds (7,037 kilograms) and maximum takeoff weight was 27,500 pounds (12,474 kilograms).

Early production aircraft were powered by a Pratt & Whitney J57-P-4 engine. This was a two-spool, axial-flow turbojet engine with a 16-stage compressor and 3-stage turbine. The J57-P-4 had a normal power rating of 8,700 pounds of thrust (38.70 kilonewtons); military power, 10,200 pounds (45.37 kilonewtons), and a maximum rating of 16,000 pounds (71.17 kilonewtons) with afterburner. The engine was 20 feet, 10 inches (6.350 meters) long and 3 feet, 5 inches (1.041 meters) in diameter.

The F8U-1 had a cruising speed of 494 knots (569 miles per hour/915 kilometers per hour). Its maximum speed was 637 knots (733 miles per hour/1,180 kilometers per hour) at Sea Level—0.95 Mach—and 860 knots (990 miles per hour/1,180 kilometers per hour) at 35,000 feet (10,668 meters)—Mach 1.50.  It had a service ceiling of 42,300 feet (12,893 meters) and combat range of 1,280 nautical miles miles (1,473 statute miles/2,371 kilometers).

The F8U Crusader was known as “The Last of the Gunfighters” because it was the last American fighter aircraft to be designed with guns as the primary armament. It carried four Colt Mark 12 20-mm autocannon with 500 rounds of ammunition. It could also carry two AIM-9 Sidewinder infrared-homing air-to-air missiles.

Because of a high accident rate, the Crusader has also been called “The Ensign Killer.”

During five years of testing, Bu. No. 138899 made 508 flights. It was donated to the Smithsonian Institution in 1960. The restored prototype is now at The Museum of Flight, Seattle, Washington.

According to information recently discovered by The Museum of Flight, fighter pilot, test pilot and future astronaut John Herschel Glenn, Jr., made his first flight in a Crusader when he flew Bu. No. 138899 on 4 May 1956. According to Glenn’s logbook, he made two flights in the prototype on that date, totaling 2 hours of flight time. Many thanks to Mike Martinez, a docent for the museum for providing this information.

John William Konrad was born 25 November 1923 at San Diego, California. He was the second of three children of  William Konrad, a salesman, and Emma Louise Stensrud Konrad.

Konrad became interested in aviation at an early age, learning to fly in a Piper Cub at the age of 15. After graduating from high school, he enlisted as a private in the U.S. Army Air Corps at San Diego, 26 February 1943. Konrad was 5 feet, 3 inches (1.60 meters) tall and weighed 118 pounds (53.5 kilograms). He trained as a pilot and flew Boeing B-17 Flying Fortress heavy bombers with the 305th Bombardment Group (Heavy), stationed at RAF Chelveston, during World War II. He later flew Douglas C-47 Skytrains during the Berlin Airlift.

Konrad married Miss Harriet Marilyn Hastings at Clearwater, Florida, 11 February 1945. They would have two children.

Following the War, Konrad was selected for the first test pilot training class at Wright Field, then was assigned to Muroc Army Airfield (Edwards Air Force Base) in California, where he graduated from the Air Force Experimental Flight Test Pilot School, Class 51-C, 19 May 1952.

Konrad resigned from the Air Force in 1953 and joined the Chance Vought Aircraft Corporation in Dallas, Texas, as a test pilot. In addition the the XF8U-1 Crusader, he also made the first flight of the Ling-Temco-Vought A-7 Corsair II, and the experimental LTV XC-142 tiltwing V/STOL transport in 1964. He was appointed Director Test Operations in 1965. Konrad retired from Vought in 1988 after 25 years with the company.

After retiring, John Konrad continued to fly a Goodyear FG-1D Corsair with Commemorative Air Force.

John William Konrad, Sr., Captain, United States Air Force, died 20 September 2006 at Dallas, Texas. He is buried at the Dallas–Fort Worth National Cemetery.

24 March 1960: Over a 1,000-kilometer course at Sternberg Point Observatory,¹ a Tupolev Tu-114 Rossiya four-engine turboprop airliner, serial number 88402, registered CCCP-76459, set eight Fédération Aéronautique Internationale flight records, including a world speed record of 871.38 kilometers per hour (541.45 miles per hour), while carrying a load of 25,000 kilograms (55,115.6 pounds).²

Colonel Ivan Moiseevich Sukhomlin.

The flight crew for these records were Tupolev Design Bureau senior test pilot Colonel Ivan Moiseevich Sukhomlin, Pilot, and Colonel Boris Mikhailovich Timoshok, Co-Pilot, and four others.

On 1 April 1960, Colonel Sukhomline flew the Tu-114 to set another seven speed records over a 2,000 kilometers course, at 857.277 kilometers per hour (532.687 miles per hour), while carrying a 20,000 kilogram payload (44,092 pounds).³

On 9 April, Colonel Sukhomlin and co-pilot Konstantine Sapielkine flew the Tu-114 over a 5,000 kilometer closed circuit, again with a 25,000 kilogram payload, at an average speed of 877.21 kilometers per hour (545.07 miles per hour). Four more FAI records were set.⁴

These are the fastest speed records ever established for any propeller-driven airplane. The records were retired by the FAI due to changes in rules.

The record-setting Tu-114 was the second production airliner.

The Tupolev Tu-114 Rossiya was a four-engine, turboprop-powered airliner developed from the Tu-95 Bear nuclear-capable long-range heavy bomber. It had a flight crew of five, two pilots, a navigator and two flight engineers, and could be configured to carry from 120 to 220 passengers, or 30,000 kilograms of cargo.

The Tu-114 made its first flight 15 November 1957 under the command of Colonel Alexei Petrovich Yakimov,  and began regular service with Aeroflot 24 April 1961.

The Tu-114 is 54.10 meters (177 feet, 6 inches) long, with a wingspan of 51.10 meters (167 feet, 8 inches) and overall height of 15.50 meters (50 feet, 10 inches). The wings are swept aft to 35° at ¼-chord, and they have significant anhedral. Total wing area is 311.1 square meters (3,348.7 square feet).

The airliner’s empty weight is 93,500 kilograms (206,132 pounds) and maximum takeoff weight is 179,000 kilograms (394,628 pounds).

The Tu-114 was powered by four Kuznetsov NK-12MV turboprop engines, each driving two contra-rotating four-bladed propellers. The NK-12 was rated at 14,795 shaft horsepower (10.89 megawatts). The NK-12 is a single-shaft axial-flow turboprop engine with a 14-stage compressor section and 5-stage turbine. The engine is 19 feet, 8.2 inches (6.000 meters) long, 3 feet, 11.3 inches (1.151 meters) in diameter, and weighs 5,181 pounds (2,350 kilograms).

The Tu-114 had a cruise speed of 770 kilometers per hour (478 miles per hour) at 9,000 meters (29,528 feet) (0.70 Mach), and a maximum speed of 894 kilometers per hour (556 miles per hour) at 8,000 meters (26,247 feet) (0.80 Mach). The airliner has a practical range of 7,000 kilometers (4,350 miles) and maximum ferry range of 8,800 kilometers (5,468 miles). The service ceiling as 12,000 meters (39,370 feet).

24 March 1960: After North American Aviation’s Chief Engineering Test Pilot, Albert Scott Crossfield, had made the first flights in the new X-15 hypersonic research rocketplane (one gliding, eight powered), NASA Chief Research Test Pilot Joseph Albert Walker made his first familiarization flight.

The X-15, 56-6670, the first of three built by North American Aviation, Inc., was carried aloft under the right wing of a Boeing NB-52A Stratofortress, 52-003, flown by John E. Allavie and Fitzhugh L. Fulton.

The rocketplane was dropped from the mothership over Rosamond Dry Lake at 15:43:23.0 local time, and Joe Walker ignited the Reaction Motors XLR-11 rocket engine. The engine burned for 272.0 seconds, accelerating Walker and the X-15 to Mach 2.0 (1,320 miles per hour/2,124.3 kilometers per hour) and a peak altitude of 48,630 feet (14,822.4 meters). Walker landed on Rogers Dry Lake at Edwards Air Force Base after a flight of 9 minutes, 8.0 seconds.

Joe Walker made 25 flights in the three X-15 rocket planes from 24 March 1960 to 22 August 1963. He achieved a maximum Mach number of 5.92, maximum speed of 4,104 miles per hour (6,605 kilometers per hour) and maximum altitude of 354,200 feet (107,960 meters).

Joe Walker was killed in a mid-air collision between his Lockheed F-104N Starfighter and a North American Aviation XB-70A Valkyrie near Barstow, California, 1 June 1966.

The number one ship, 56-6670, made 81 of the 199 flights of the X-15 Program. It was the first to fly, and also the last, 24 October 1968. Today, it is in the collection of the Smithsonian Institution National Air and Space Museum.

24 March 1944: At about 2230 hours, the first of 76 Allied prisoners of war interred at Stammlager Luft III (Stalag Luft III) began to escape through a 30-foot-deep (9 meters), 320-foot-long (98 meters) tunnel, code-named “Harry.”

The prison, located just south of Sagan (Żagań) in East Silesia (now a part of Poland) was specially constructed to house captured Royal Air Force and other Allied airmen, and was controlled by the German air force, the Luftwaffe. Prior to this escape, the German captors had discovered at least 98 tunnels at the prison.

The weather was the coldest in thirty years and five feet of snow lay on the ground. The last escapee left the tunnel at 0455, 25 March. Of the 76 prisoners who escaped, 73 were soon recaptured, and of those, 50 were murdered by the Gestapo.

Popularly known as “The Great Escape,” this was the subject of a 1950 book, The Great Escape, by Paul Brickhill, who was a POW at the prison. His book was adapted into a very popular motion picture, “The Great Escape,” in 1963.
