8 June 1966: During a publicity photo formation flight, a Lockheed F-104N Starfighter, N813NA, flown by NASA Chief Research Test Pilot Joseph A. Walker, was caught in the wingtip vortices of the North American Aviation XB-70A-2 Valkyrie, 62-0207, the second prototype Mach 3+ strategic bomber. The Starfighter rolled up and across the Valkyrie. The two airplanes collided, with the F-104 taking off the Valkyrie’s vertical fins, then exploding.

The Valkyrie continued to fly straight and level for 16 seconds before it began to roll inverted. The B-70’s pilot, Alvin S. White, was able to eject, though he was severely injured. Joe Walker and B-70 co-pilot Major Carl S. Cross, United States Air Force, were killed.

Still photographs and motion picture film of the formation were being taken from Clay Lacy’s Gates Lear Jet. The photos were for a General Electric publicity campaign showing U.S. military aircraft that were powered by GE engines. Air Force procedures for requesting and approval of publicity flights were not properly followed and it is likely this flight would not have been approved had they been.

Reportedly, just prior to the collision, Walker radioed, “I’m opposing this mission. It is too turbulent and it has no scientific value.”

3 June 1961: At the Paris Air Show, Aéroport de Paris – Le Bourget, Paris, France, the Blériot, Harmon and Mackay Trophy-winning Convair B-58A-10-CF Hustler, 59-2451, The Firefly, crashed, killing the aircrew, Major Elmer E. Murphy, Major Eugene Moses, and First Lieutenant David F. Dickerson. The B-58 was totally destroyed.
Only days earlier, The Firefly—with a different aircrew—had set a new speed record for its flight from New York to Paris.
On leaving Le Bourget for the return trip to the United States, Major Murphy engaged in low-altitude aerobatics. There are reports that while performing a slow roll, the bomber entered a cloud bank. The pilot lost visual reference, but the roll caused the attitude indicator to exceed its limits. Disoriented and without instrument flight capability, the B-58 crashed.
The Sunday Herald (Provo, Utah) reported:
. . . The B-58 took off with five other American supersonic jets for the demonstration and flew back over the airfield at normal speed.
Then the plane started to make what looked from the ground like a “barrel” maneuver, a roll over, and suddenly disappeared from the view of the audience at the airfield. . . .
. . . An eyewitness said the plane appeared to explode in flight after making a “barrel roll.”
It was “transformed into a ball of fire,” said Dr. J.P Duchon. “We heard a tremendous explosion at the same time.” The B-58 crashed into some farm acreage gouging a 15-feet-deep crater in the ground.
The Fort Worth Star-Telegram published the following:
. . . According to reports from [John] Randel [correspondent for the Paris edition of the New York Herald-Tribune] and the Associated Press, this is the way the crash occurred:
The delta-wing bomber streaked passed the control tower and disappeared into the overcast. No one at Le Bourget Airport, where the air show was being staged, saw any sign of the crash, which occurred about 5 p.m. Paris time (10 a.m. Fort Worth time).
Wheat Field.
But at the little town of Louvres, three miles north of the airport, there was a tremendous explosion.
The needle-nose bomber plunged into a wheat field. This was about 10 minutes after takeoff.
The nearest building was from 500 to 800 yards away.
Louvres police said they did not know whether the plane exploded in air or when it hit the ground.
Fuel from the plane caught fire, sending up billows of smoke. Huge craters were cut into the ground by plummeting wreckage, indicating an aerial explosion.
About 10 fire trucks were soon at the scene spraying water on the burning debris.
Helicopter Lift.
One report said the plane had completed a slow roll and was trying a snap roll when two or three of its four engines ripped off. This report was strictly unofficial. . . .

3 June 1942: After a U.S. Navy PBY patrol bomber sighted a task force of the Japanese fleet approaching Midway Atoll, nine U.S. Army Air Force Boeing B-17E Flying Fortress heavy bombers of the 431st Bombardment Squadron (Heavy), 11th Bombardment Group (Heavy), under the command of Lieutenant Colonel Walter C. Sweeney, Jr., launched from the island at 1230 hours.
The B-17s were equipped with bomb bay “Tokyo tanks” and each was armed with four 600 pound (272 kilogram) bombs.
At 1624 hours, the bomber force located Admiral Raizo Tanaka’s Midway Occupation Group 570 miles (917 kilometers) west of the island. They attacked in three flights of three, at 8,000, 10,000 and 12,000 feet (2,440, 3,050 and 3,660 meters). Although they reported damage to several ships, in fact none were hit.

26 May 1961: The Firefly, the Blériot Trophy-winning Convair B-58A-10-CF Hustler, serial number 59-2451, assigned to the 43rd Bombardment Wing, Carswell Air Force Base, Fort Worth, Texas, set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Recognized Course by flying from Washington, D.C. to Paris in 3 hours, 39 minutes, 49 seconds, for an average speed of 1,687.69 kilometers per hour (1,048.68 miles per hour).¹
During the same flight, the B-58 flew the New York to Paris segment in 3 hours, 14 minutes, 44.53 seconds, at an average speed of 1,753.16 kilometers per hour (1,089.36 miles per hour).
The aircrew, Major William R. Payne, Aircraft Commander, Captain William L. Polhemus, Navigator, and Captain Raymond R. Wagener, Defensive Systems Officer, won the Harmon and Mackay Trophies for this flight.

The B-58A Hustler was a high-altitude Mach 2 strategic bomber which served with the United States Air Force from 1960 to 1970. It was crewed by a pilot, navigator/bombardier and a defensive systems operator, each located in individual cockpits. The aircraft had a delta-winged configuration similar to the Convair F-102A Delta Dagger and F-106 Delta Dart supersonic interceptors. The fuselage incorporates the “Area Rule” which resulted in a “wasp waist” or “Coke bottle” shape for a significant reduction in aerodynamic drag. The airplane’s only control surfaces are two “elevons” and a rudder. There are no flaps.
The “Hustler” was 96.8 feet (29.5 meters) long, with a wing span of 56.8 feet (17.3 meters) and an overall height of 31.4 feet (9.6 meters). The wings’ leading edges were swept back at a 60° angle. The wings had a 3°0′ angle of incidence, 2°14′ dihedral, and a total area of 1,542.5 square feet (143.3 square meters).
The B-58A had an empty weight of 51,061 pounds (23,161 kilograms). Its Maximum Takeoff Weight (MTOW) was 90,000 pounds (40,823 kilograms), but once airborne, it could take on additional fuel from a tanker, raising the bomber’s maximum weight to 125,147 pounds (56,766 kilograms).
The B-58A was powered by four General Electric J79-GE-5 afterburning turbojet engines, suspended under the wings from pylons. These were single-shaft axial-flow engines with a 17-stage compressor and 3-stage turbine. The J79-GE-5 had a continuous power rating of 9,700 pounds of thrust (43.15 kilonewtons), Military Power, 10,000 pounds of thrust (44.49 kilonewtons), and Maximum Power, 15,600 pounds (69.39 kilonewtons) with afterburner. (All ratings at 7,460 r.p.m.) The engine was 16 feet, 10.2 inches (5.131 meters) long and 3 feet, 2.0 inches (0.889 meters) in diameter. It weighed 3,570 pounds (1,619 kilograms).
The bomber had a cruise speed of 626 miles per hour (1,007 kilometers per hour) from 30,000 to 50,000 feet (9,144–15,240 meters), and a maximum speed of 1,319 miles per hour (2,124 kilometers per hour) at 56,100 feet (17,099 meters). The B-58’s service ceiling was 67,200 feet (20,483 meters).
Jet fuel (JP-4) was carried in three tanks inside the airplane’s fuselage, and two tanks in a streamlined drop tank. The total capacity of the five tanks was 15,369 gallons (58,178 liters). Its combat radius was 2,589 miles (4,167 kilometers) and the maximum ferry range was 6,483 miles (10,434 kilometers).
The B-58 weapons load was a combination of W-39, B43 or B61 nuclear bombs. The W-39 was carried in the centerline pod. (A two-component mission pod was also available.) The W-39 was the same warhead used on the PGM-11 Redstone intermediate range ballistic missile and the SM-62 Snark intercontinental cruise missile. It was a two-stage radiation-implosion thermonuclear warhead with an explosive yield of 3.8 megatons. The warhead weighed 6,230 pounds (2,826 kilograms). The B-43 and B-61 bombs were carried on four hardpoints under the fuselage.
There was a defensive General Electric M61 Vulcan 20 mm rotary cannon mounted in the bomber’s tail, with a maximum 1,040 rounds of ammunition. The gun was remotely-controlled by the Defensive Systems Officer.
