21 March 1962: A black bear named “Yogi” was ejected from a supersonic Convair B-58A Hustler to test the B-58’s escape capsule. Ejected at 35,000 feet (10,668 meters) from a B-58 flying at Mach 1.3 (approximately 870 miles per hour/1,400 kilometers per hour), the bear landed unharmed 7 minutes, 49 seconds later.

Previous testing with human subjects had resulted in fatalities so it was decided to continue with animal subjects while problems were resolved. Black bears (Ursus americanus) were used for these tests because their internal organs are arranged similar to humans.

The rocket booster carried the capsule 225 feet (69 meters meters) above the B-58 before beginning its descent.

Regrettably, although the bears survived the ejection tests, they were killed so that their organs could be examined. This would not be acceptable today.

5 March 1962: Operation Heat Rise. Two Convair B-58 Hustler supersonic bombers from the 65th Bombardment Squadron, 43rd Bombardment Wing, Carswell Air Force Base, Texas, took off at sunrise and headed west to Los Angeles, California. Off the Pacific coast they refueled from a Boeing KC-135A Stratotanker, then headed east at maximum speed. They were to enter a radar starting gate at Los Angeles, but the radar did not pick them up so they returned to the tanker, topped off the fuel tanks again, then proceeded east once again. This time their entry was visually confirmed.

Both B-58s had been assigned a block altitude of Flight Level 250 to Flight Level 500 (between 25,000 and 50,000 feet, or 7,620 to 15,240 meters) by the Federal Aviation Administration, and all other aircraft were cleared from those altitudes along the course. The flight outbound from Los Angeles was at 50,000 feet (15,240 meters) at speeds above Mach 2.

Under normal conditions, the maximum speed of the B-58 was limited to a skin temperature of 115 °C. (239 °F.) to prevent the aluminum honeycomb skin panels from delaminating. For this speed run, Convair engineers had authorized a temperature of 125 °C. (257 °F.), which would allow the two bombers to exceed 1,400 miles per hour (2,253 kilometers per hour). Sensors were placed in the skin to monitor the temperature rise (which gave the operation its name: “Heat Rise”).

The first B-58, call sign “Tall Man Five-Five,” had a problem with the navigation radar and had some difficulty locating their tanker, but finally were able to. The B-58s descended to 25,000 feet over Kansas for the third refueling and over a 21-minute period, took on 85,000 gallons (321,760 liters) of fuel, climbed back to 45,000 feet (13,716 meters) and then continued on to New York.

The Cowtown Hustler ¹ crossed the radar gate at New York with an elapsed time of 2:00:58.71 for the West-to-East flight, averaging 1,214.65 miles per hour (1,954.79 kilometers per hour). The second B-58, Tall Man Five-Six, was one minute behind.

Passing New York, the two B-58 Hustlers proceeded over the Atlantic Ocean and rendezvoused with tankers for a fourth aerial refueling, then headed back west to Los Angeles. Shortly after passing New York, Tall Man Five-Six developed mechanical troubles and had to withdraw from the round-trip record attempt.

Once again over Kansas, Cowtown Hustler refueled for a fifth time then continued back to Los Angeles. The East-to-West leg from New York to Los Angeles was completed in an elapsed time of 2:15:50.08, averaging 1,081.81 miles per hour (1,741.00 kilometers per hour).

The total elapsed time, Los Angeles–New York–Los Angeles, was 4 hours, 41 minutes, 14.98 seconds (4:41:14.98), for an average speed of 1,044.97 miles per hour (1,681.71 kilometers per hour). The crew and the airplane established three National Aeronautic Association U.S. national records for Speed Over A Recognized Course.

At Los Angeles, the flight crew, Captain Robert G. Sowers, Pilot, Captain Robert MacDonald, Navigator, and Captain John T. Walton, were congratulated by General Thomas S. Power, Chief of Staff, Strategic Air Command, and each airman was awarded the Distinguished Flying Cross.

For the eastbound transcontinental flight, the crew won the Bendix Trophy, and for “the most meritorious flight of the year,” they were also awarded the Mackay Trophy. Their records still stand.

The Convair 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, located in individual cockpits. The aircraft is a delta-winged configuration similar to the Convair F-102A Delta Dagger and F-106 Delta Dart supersonic interceptors.

The Hustler is 96 feet, 10 inches (29.515 meters) long, with a wing span of 56 feet, 10 inches (17.323 meters) and an overall height of 31 feet 5 inches (9.576 meters). 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, and there are no flaps.

The B-58’s delta wing has a total area of 1,542.5 square feet (143.3 square meters) and the leading edges are swept back at a 60° angle. The wing has an angle of incidence of 3° and 2° 14′ dihedral (outboard of Sta. 56.5).

The B-58A had an empty weight of 51,061 pounds (23161 kilograms), or 53,581 pounds (24,304 kilograms) with the MB-1 pod. The maximum takeoff weight was 158,000 pounds (71,668 kilograms).

The B-58A was powered by four General Electric J79-GE-5 axial-flow afterburning turbojet engines, suspended under the wings from pylons. This was a single-shaft engine with a 17-stage compressor and 3-stage turbine. It had a Normal Power rating of 9,700 pounds of thrust (43.148 kilonewtons). The Military Power rating was 10,000 pounds (44.482 kilonewtons), and it produced a maximum 15,600 pounds (69.392 kilonewtons) at 7,460 r.p.m., with afterburner. The J79-GE-5 was 16 feet, 10.0 inches (5.131 meters) long and 2 feet, 11.2 inches (0.894 meters) in diameter. It weighed 3,570 pounds (1,619 kilograms).

The bomber had a cruise speed of 544 knots (626 miles per hour/1,007 kilometers per hour) and a maximum speed of 1,147 knots (1,320 miles per hour/2,124 kilometers per hour) at 67,000 feet (20,422 meters). The B-58A had a combat radius of 4,225 nautical miles (4,862 statute miles/7,825 kilometers). Its maximum ferry range was 8,416 nautical miles (9,685 statute miles/15,586 kilometers).

The B-58 weapons load was a combination of Mark 39, B43 or B61 thermonuclear bombs. The weapons could be carried in a jettisonable centerline pod, which also carried fuel. The four of the smaller bombs could be carried on underwing hardpoints. There was a General Electric M61 20 mm rotary cannon mounted in the tail, with 1,200 rounds of ammunition, and controlled by the Defensive Systems Officer.

116 were built and they served the Strategic Air Command until January 1970 when they were sent to Davis-Monthan AFB, Tucson, Arizona for long-term storage.

14 January 1961: Lt. Col. Harold E. Confer, Lt. Col. Richard Weir and Major Howard Bialas, flying Convair B-58A-10-CF Hustler 59-2441, Roadrunner, obliterated the FAI closed-course speed records established only two days earlier by another B-58 crew flying 59-2442. They averaged 2,067.58 kilometers per hour (1,284.73 miles per hour) over a 1,000 kilometer closed circuit, more than 200 miles per hour faster, and set three Fédération Aéronautique Internationale records. They were awarded the Thompson Trophy.

59-2441 was sent to The Boneyard in 1970, and along with its sister, 59-2442, scrapped in 1977.

14 September 1962: At Edwards Air Force Base, in the high desert of southern California, Major Fitzhugh L. Fulton, Jr., United States Air Force, with Captain William R. Payne, USAF, and civilian flight test engineer C.R. Haines, flew a Convair B-58A-10-CF Hustler, serial number 59-2456, to a record 26,017.93 meters (85,360.66 feet) while carrying a 5,000 kilogram payload. This set a Fédération Aéronautique Internationale (FAI) World Record for Altitude in both the 2,000 kilogram (4,409.25 pounds) ¹ and 5,000 kilogram (11,023.11 pounds) ² classes.

Fitzhugh L. Fulton, Jr., 1942.

Fitzhugh Lee Fulton, Jr., was born 6 June 1925 at Blakeley, Georgia. He was the son of Fitzhugh Lee Fulton and Manila T. Fulton. He graduated from Columbus High School, Columbus, Georgia, in 1942. He later studied at Auburn University, Auburn, Alabama, and the University of Oklahoma, Norman, Oklahoma (just south of Oklahoma City). he graduated from Golden Gate University, San Francisco, California.

Fitz Fulton married Miss Erma I. Beck at Tucson, Arizona, 16 December 1945.

He entered the U.S. Army Air Corps in 1943. He flew the Douglas C-54 Skymaster transport during the Berlin Airlift and Douglas B-26 Invaders during the Korean War. Fulton graduated from the Air Force Experimental Test Pilot School in 1952. He served as project test pilot for the Convair B-58 Hustler supersonic bomber. At Edwards AFB, he flew the B-52 “motherships” for the X-15 Program. He flew the North American XB-70A Valkyrie to more than Mach 3. When Fulton retired from the Air Force in 1966, he was a lieutenant colonel assigned as Chief of Bomber and Transport Test Operations.

Fitz Fulton continued as a test pilot for NASA, flying as project pilot for the YF-12A and YF-12C research program. He flew all the early test flights of the NASA/Boeing 747 Shuttle Carrier Aircraft and carried the space shuttle prototype, Enterprise. By the time he had retired from NASA, Fulton had flown more than 16,000 hours in 235 aircraft types.

Fitzhugh Lee Fulton, Jr., died at Thousand Oaks, California, 4 February 2015, at the age of 89 years.

The J79-GE-5 was 16 feet, 10.2 inches (5.136 meters) long and 3 feet, 2.0 inches (0.965 meters) in diameter.

The bomber had a cruise speed of 610 miles per hour (981.7 kilometers per hour) and a maximum speed of 1,325 miles per hour (2,132.4 kilometers per hour). The service ceiling is 64,800 feet (19,751 meters). Unrefueled range is 4,400 miles (7,081 kilometers). Maximum weight is 168,000 pounds (76,203.5 kilograms).

The B-58 weapons load was a combination of a W-39 warhead, and/or Mk.43 or B61 nuclear bombs. The W-39 warhead, the same used with the Redstone IRBM or Snark cruise missile, was carried in a jettisonable centerline pod, which also carried fuel for the aircraft. The smaller bombs were carried on underwing hardpoints. For defense, there was a General Electric M61 Vulcan 20×102 mm six-barreled rotary cannon mounted in the tail, with 1,200 rounds of linked ammunition, controlled by the Defensive Systems Officer.

Convair B-58A-10-CF 59-2456 was assigned to the 43rd Bombardment Wing at Carswell Air Force Base, Texas until 1969 when it was placed in storage at Davis-Monthan Air Force Base, Tucson, Arizona, 9 December 1969. The record-setting strategic bomber was scrapped 1 June 1977.
