12 August 1977: At Edwards Air Force Base, California, the prototype Space Shuttle Oriter, Enterprise, (OV-101) was mated to the Boeing 747-100 Shuttle Carrier Aircraft, N905NA, call sign NASA 905, for the first of five approach and landing test flights. On Enterprise‘ flight deck were astronauts Fred Haise and Gordon Fullerton. The crew of NASA 905 were NASA test pilots Fitz Fulton and Tom McMurty with Vic Horton and Skip Guidry as flight engineers.

An estimated 65,000 people had come to Edwards to watch and at 8:00, Fitz Fulton began the take off roll down Runway 22. For the next 38 minutes the spacecraft/aircraft combination climbed together into the desert sky. After reaching an altitude of 24,100 feet (7,346 meters), Fulton put the Shuttle Carrier Aircraft into a shallow dive. At 8:48 a.m., Fred Haise fired the seven explosive bolts holding the two craft together. The 747 entered a descending left turn while Haise banked Enterprise away to the right.

As Enterprise made its gliding descent, Haise and Fullerton experimented with the prototype’s flight characterisics and handling. The Shuttle Orbiter touched down on Rogers Dry Lake at 185 miles per hour (297.7 kilometers per hour), and rolled for two miles (3.22 kilometers) before coming to a complete stop.

The first free flight of Enterprise lasted 5 minutes, 21 seconds.

5 August 1954: The first production Boeing B-52A Stratofortress, B-52A-1-BO 52-001, made its first flight from Boeing Field, Seattle, Washington.

The B-52A differed from the XB-52 and YB-52 in that its cockpit was arranged for side-by-side seating, rather than the B-47-type tandem arrangement of the prototypes. It also had an inflight refueling system allowing it to receive fuel from an airborne KC-97 tanker.

52-001 was used as a service test aircraft along with sisterships 52-002 and 52-003. It was scrapped at Tinker Air Force Base in 1961.

17 July 1996, 8:31 p.m., Eastern Daylight Time: Trans World Airlines (TWA) Flight 800, a Boeing 747-131, FAA registration N93119, was enroute from New York to Paris with 212 passengers and 18 crewmembers persons aboard, and had been cleared to climb from FL130 (13,000 feet, 3,962 meters) to FL150 (15,000 feet, 4,572 meters). The airliner exploded in mid-air, 8.1 miles (13.04 kilometers) south of E. Moriches, New York.

The flight crew of an Eastwind Air Lines flight reported the explosion to Air Traffic Control. Many witnesses described an ascending streak of orange light, originating near the surface and ending in a fireball. Burning debris fell into the sea. All 230 persons on board were killed.

The National Transportation Safety Board determined that the explosion was a result of fuel vapor in the center wing tank being ignited by a short circuit.

PROBABLE CAUSE: “An explosion of the center wing fuel tank (CWT), resulting from ignition of the flammable fuel/air mixture in the tank. The source of ignition energy for the explosion could not be determined with certainty, but, of the sources evaluated by the investigation, the most likely was a short circuit outside of the CWT that allowed excessive voltage to enter it through electrical wiring associated with the fuel quantity indication system.

“Contributing factors to the accident were the design and certification concept that fuel tank explosions could be prevented solely by precluding all ignition sources and the design and certification of the Boeing 747 with heat sources located beneath the CWT with no means to reduce the heat transferred into the CWT or to render the fuel vapor in the tank nonflammable.”

The 747-100 series was the first version of the Boeing 747 to be built. It was designed to carry 366 to 452 passengers,depending on seating configuration. It is 231 feet, 10.2 inches (70.668 meters) long with a wingspan of 195 feet, 8 inches (59.639 meters) and overall height of 63 feet, 5 inches (19.329 meters). The interior cabin width is 20 feet (6.096 meters), giving it the name “wide body.” Its empty weight is 370,816 pounds (168,199 kilograms) and the Maximum Takeoff Weight (MTOW) is 735,000 pounds (333,390 kilograms).

The 747-100 is powered by four Pratt and Whitney JT9D-7A turbofan engines which produce 47,670 pounds of thrust, each, with water injection (2½ minutes). Its cruise speed is 0.84 Mach (555 miles per hour, 893 kilometers per hour) at 35,000 feet (10,668 meters) and it maximum range is 6,100 miles (9,817 kilometers).

Boeing 747-131 N93119 was one of the oldest 747s in service, having been delivered to TWA 27 October 1971. At the time off its destruction the airframe had accumulated 93,303 flight hours (TTAF).

17 July 1962: At 9:31:10.0 a.m., the Number 3 North American Aviation X-15, 56-6672, was airdropped from a Boeing NB-52A Stratofortress, 52-003, over Delamar Dry Lake, Nevada. Air Force project test pilot Major Robert M. (“Bob”) White was in the cockpit. This was the 62nd flight of the X-15 Program, and Bob White was making his 15th flight in an X-15 hypersonic research rocketplane. The purpose of this flight was to verify the performance of the Honeywell MH-96 flight control system which had been installed in the Number 3 ship. Just one minute before drop, the MH-96 failed, but White reset his circuit breakers and it came back on line.

After dropping from the B-52’s wing, White fired the X-15’s Reaction Motors XLR-99 rocket engine and began to accelerate and climb. The planned burn time for the 57,000-pound-thrust engine was 80.0 seconds. It shut down 2 seconds late, driving the X-15 well beyond the planned peak altitude for this flight. Instead of reaching 280,000 feet (85,344 meters), Robert White reached 314,750 feet (95,936 meters). This was an altitude gain of 82,190 meters (269,652 feet), which was a new Fédération Aéronautique Internationale (FAI) world record.¹ The rocketplane reached Mach 5.45, 3,832 miles per hour (6,167 kilometers per hour).

Because of the increased speed and altitude, White was in danger of overshooting his landing at Edwards Air Force Base in California. He crossed the north end of Rogers Dry Lake and crossed the “high key”—the point where the X-15 landing maneuver begins—too high and too fast at Mach 3.5 at 80,000 feet (24,384 meters). Without power, White made a wide 360° turn over Rosamond Dry Lake then came back over the high key at a more normal 28,000 feet (8,534.4 meters) and subsonic speed. He glided to a perfect touch down, 10 minutes, 20.7 seconds after being dropped from the B-52.

This was the first time that a manned aircraft had gone higher than 300,000 feet (91,440 meters). It was also the first flight above 50 miles. For that achievement, Bob White became the first X-15 pilot to be awarded U.S. Air Force astronaut wings. His 314,750-foot altitude (95,936 meters) also established a Fédération Aéronautique Internationale (FAI) world altitude record, which will probably never be broken. To qualify, a new record would have to exceed White’s altitude by at least 3%, or more than 324,419 feet (98,882.9 meters). As the FAI-recognized boundary of Space is 328,083.99 feet (100,000 meters), any prospective challenger would have to hit a very narrow band of the atmosphere.

Major White had been the first pilot to fly faster than Mach 4, Mach 5 and Mach 6. He was the first to fly over 200,000 feet, then over 300,000 feet. He was a graduate of the Air Force Experimental Test Pilot School and flew tests of many aircraft at Edwards before entering the X-15 program. He made at total of sixteen X-15 flights.

A P-51 Mustang fighter pilot with the 355th Fighter Group in World War II, he was shot down by ground fire on his fifty-third combat mission, 23 February 1945, and captured. He was held as a prisoner of war until the war in Europe came to an end in April 1945.

After the war, White accepted a reserve commission while he attended college to earn a degree in engineering. He was recalled to active duty during the Korean War, and assigned to a P-51 fighter squadron in South Korea. Later, he commanded the 22nd Tactical Fighter Squadron (flying the Republic F-105 Thunderchief supersonic fighter bomber) based in Germany, and later, the 53rd TFS. During the Vietnam War, Lieutenant Colonel White, as the deputy commander for operations of the 355th Tactical Fighter Wing, flew seventy combat missions over North Vietnam in the F-105D, including leading the attack against the Paul Doumer Bridge at Hanoi, 11 August 1967, for which he was awarded the Air Force Cross.

He next went to Wright-Patterson AFB where he was director of the F-15 Eagle fighter program. In 1970 he returned to Edwards AFB as commander of the Air Force Flight Test Center. White was promoted to Major General in 1975.

General White retired from the U.S. Air Force in 1981. He died 10 March 2010.
