9 November 1961: Major Robert M. White, U.S. Air Force, became the first pilot to fly faster than Mach 6 when he flew the number two North American Aviation X-15 hypersonic research rocketplane, 56-6671, to Mach 6.04.

This was the 45th flight of the X-15 program, and Bob White’s 11th flight. The purpose of this test flight was to accelerate 56-6671 to its maximum velocity, to gather data about aerodynamic heating at hypersonic speeds, and to evaluate the rocketplane’s stability and handling.

The X-15 was carried to approximately 45,000 feet (13,716 meters) while mounted to a pylon under the right wing of the “mothership,” a Boeing NB-52B Stratofortress, 52-008, nicknamed Balls 8. White was dropped over Mud Lake, Nevada, approximately 200 miles (322 kilometers) north of Edwards Air Force Base. Once clear of the B-52, he ignited the Reaction Motors XLR99-RM-1 rocket engine, and with it producing 57,000 pounds of thrust (253.549 kilonewtons) at full throttle, the X-15 accelerated for 86.9 seconds. The rocketplane reached a peak altitude of 101,600 feet (30,968 meters). Its speed was Mach 6.04 (4,094 miles per hour/6,589 kilometers per hour).

White stated in his post-flight report, “When I leveled off at about 101,000 feet, I made a little downward pressure [on the control stick], because I didn’t want to be climbing. I remember. . . going along watching that [Mach] meter reading roughly 6,000 feet per second, [and] saying to myself, ‘Go, go, go, go!’ We did just crack it, because we knew that bringing all the proper things together, we could or should get just about Mach 6.”

In order to achieve the goal, the flight plan called for pushing the LR-99 to the point of exhaustion instead of manually shutting down the engine at an arbitrary point. White said, “The shutdown seemed to be a little bit different this time, compared with a shutdown by closing the throttle. It seemed to occur over a longer time interval.”

“The airplane really did get hot on those flights. Temperatures in excess of 1,300 °F. were recorded. Parts of the airplane glowed cherry red and softened up a bit during those flights. The airplane got so damned hot that it popped and banged like an old iron stove. It spewed smoke out of its bowels and it twitched like frog legs in a skillet. But it survived.”

As the X-15 decelerated through Mach 2.4, the right side windshield shattered, leaving it completely opaque. On Bob White’s previous flight, the left windshield had also broken. Fortunately, in both cases, only the outer layer of the dual pane glass broke. The reduced visibility made the approach difficult to judge, but White made a successful landing, touching down on Rogers Dry Lake after a flight of 9 minutes, 31.2 seconds duration.

A P-51 Mustang fighter pilot in World War II, Robert M. White was shot down on his 52nd combat mission in February 1945 and captured. He was held as a prisoner of war until the war in Europe came to an end in April 1945. White was recalled to active duty during the Korean War. 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.

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 made at total of sixteen X-15 flights.

After leaving the X-15 program, Bob White returned to operational duties. Later, he flew 70 combat missions over North Vietnam in the Republic F-105 Thunderchief supersonic fighter bomber, 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 systems program. 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.

12 August 1960: At Edwards Air Force Base, California, Major Robert M. White flew the North American Aviation X-15 rocketplane to an altitude of 136,500 feet (41,605 meters), exceeding the previous unofficial record of 126,200 feet (38,466 meters) set by the late Captain Iven C. Kincheloe, Jr., with the Bell X-2, 7 September 1956.

Iven Kincheloe had been assigned as the Air Force’s project pilot for the X-15. When he was killed on a routine flight, Bob White was designated to replace him.

This was White’s fourth flight in an X-15, and the 19th flight of the X-15 Program. The Number 1 rocketplane, serial number 56-6670, was carried aloft under the right wing of the “mothership,” Boeing NB-52A Stratofortress 52-003. At 08:48:43.0 a.m., PDT, 56-6670 was dropped over Silver Lake, near the Nevada-California border. White fired the two Reaction Motors XLR11-RM-13 rocket engines and they burned for 256.2 seconds.

This flight took place in Phase II of the Program and was intended to gradually increase the envelope of X-15 performance with the XLR11 engines while waiting for the much more powerful XLR99. The purpose of Flight 19 was to reach maximum altitude in order to test the rocketplane’s stability and controllability above the atmosphere.

The X-15 accelerated to Mach 2.52, 1,773 miles per hour (2,853 kilometers per hour) while climbing at nearly a 70° angle and reached a peak altitude of 136,500 feet (41,605 meters). After engine shutdown, White glided to a landing on Rogers Dry Lake and touched down. The duration of the flight was 11 minutes, 39.1 seconds.

Neither Kincheloe’s or White’s altitudes are recognized as records by the Fédération Aéronautique Internationale(FAI). Over the next few years, the X-15 would reach to nearly three times higher.

The President of the United States of America, authorized by Title 10, Section 8742, United States Code, takes pleasure in presenting the Air Force Cross to Colonel Robert M. White (AFSN: 0-24589A), United States Air Force, for extraordinary heroism in military operations against an opposing armed force as an F-105 Mission Commander and Pilot of the 355th Tactical Fighter Wing, Takhli Royal Thai Air Base, Thailand, in action near Hanoi, North Vietnam, on 11 August 1967. On that date, Colonel White led the entire combat force against a key railroad and highway bridge in the vicinity of Hanoi. In spite of 14 surface-to-air missile launches, MiG interceptor attacks, and intense anti-aircraft artillery fire, he gallantly led the attack. By being the first aircraft to dive through the dark clouds of bursting flak, Colonel White set an example that inspired the remaining attacking force to destroy the bridge without a single aircraft being lost to the hostile gunners. Through his extraordinary heroism, superb airmanship, and aggressiveness in the face of hostile forces, Colonel White reflected the highest credit upon himself and the United States Air Force.

3 August 1962

3 August 1962: Following his record-setting flight into space aboard an X-15 hypersonic research rocketplane, 17 July 1962, Major Robert M. White, U.S. Air Force, was featured with a cover photograph on the LIFE Magazine issue for the week of 3 August 1962. LIFE was the most prestigious news magazine of its time.

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 (80.47 kilometers). 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 the Kármán line (100 kilometers, or 328,083.99 feet), 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 (60,960 meters), then over 300,000 feet (91,440 meters). 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 in World War II, Bob White was shot down on his 52nd combat mission in February 1945 and captured. He was held as a prisoner of war until the war in Europe came to an end in April 1945. White was recalled to active duty during the Korean War and was assigned to a fighter squadron stationed in Japan. Later, he flew 70 combat missions over North Vietnam in the Republic F-105 Thunderchief supersonic fighter bomber, including leading the attack against the Paul Doumer Bridge at Hanoi, 11 August 1967, for which he was awarded the Air Force Cross.

Colonel White next went to Wright-Patterson Air Force Base, Ohio, where he was director of the McDonnell Douglas F-15 Eagle systems program. He then returned to Edwards Air Force Base, California, 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 17 March 2010.

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.

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.
