| Aero Spacelines Super Guppy to ferry X-24 and HL-10 The Aero Spacelines B377SG Super Guppy was at Dryden in May, 1976, to ferry the X-24 and HL-10 lifting bodies from the Center to the Air Force Museum at Wright-Patterson Air Force Base, Ohio. The oversized cargo aircraft is a further modification of the B377PG Pregnant Guppy, which was built to transport outsized cargo for NASA's Apollo program, primarily to carry portions of the Saturn V rockets from the manufacturer to Cape Canaveral. The original Guppy modification incorporated the wings, engines, lower fuselage and tail from a Boeing 377 Stratocruiser with a huge upper fuselage more than 20 feet in diameter. The Super Guppy further expanded the fuselage, replaced the original piston engines with more powerful turbo-prop engines, and added a taller vertical tail for better lateral stability. |

| Annotated photo shows rear view of X-24A lifting body This annotated photo shows a rear view of the X-24A lifting body research vehicle, emphasizing the control surfaces used for the subsonic portions of the aircraft’s flights. The X-24A was flown 28 times in the program that, like the HL-10, validated the concept that a Space Shuttle vehicle could be landed unpowered. The fastest speed achieved by the X-24A was 1,036 miles per hour (mph--Mach 1.6). Its maximum altitude was 71,400 feet. It was powered by an XLR-11 rocket engine with a maximum theoretical vacuum thrust of 8,480 pounds. |

Air Force Maj. Jerauld Gentry at the controls for its first powered flight on March 19, 1970. The X-24 was one of a group of lifting bodies flown by the NASA Flight Research Center (now Dryden Flight Research Center), Edwards, California, in a joint program with the U.S. Air Force at Edwards Air Force Base from 1963 to 1975. The lifting bodies were used to demonstrate the ability of pilots to maneuver and safely land wingless vehicles designed to fly back to Earth from space and be landed like an airplane at a predetermined site. |

| Martin Marietta X-24B ground check before first flight Once a new research vehicle is delivered to Dryden from the contractor, it must undergo months of ground checkout before making its first flight. The X-24B lifting body is no exception. Here it is shown undergoing landing gear drop tests. As part of the modifications to convert the vehicle from the X-24A configuration, the nose gear from an F11F-1 was retrofitted to the X-24B. In these tests, the X-24B's nose was raised a measured distance above the hangar floor (an engineer can be seen holding a tape measure), and then released, allowing the nose gear to hit the floor. This tested the landing gear's ability to withstand the shock of touchdown, without sustaining damage to it or the aircraft's structure. |

| Martin Marietta X-24B lifting body research vehicle The sleek, futuristic shape of the Martin Marietta X-24B lifting body research vehicle can be clearly seen in this look-down view of the aircraft on Rogers Dry Lake, adjacent to the NASA Flight Research Center, Edwards, California. Martin Marietta X-24A was later modified into the X-24B. The bulbous shape of the X-24A was converted into a "flying flatiron" shape with a rounded top, flat bottom, and double delta platform that ended in a pointed nose. The X-24B demonstrated that accurate unpowered reentry vehicle landings were operationally feasible. Top speed achieved by the X-24B was 1,164 mph and the highest altitude it reached was 74,130 feet. |

| NASA lifting body on Rogers Dry Lake, Edwards The wingless, lifting body aircraft sitting on Rogers Dry Lake at what is now NASA's Dryden Flight Research Center, Edwards, California, from left to right are the X-24A, M2-F3 and the HL-10. The lifting body aircraft studied the feasibility of maneuvering and landing an aerodynamic craft designed for reentry from space. These lifting bodies were air launched by a B-52 mother ship, then flew powered by their own rocket engines before making an unpowered approach and landing. They helped validate the concept that a space shuttle could make accurate landings without power. The X-24A flew from April 17, 1969 to June 4, 1971. The M2-F3 flew from June 2, 1970 until December 21, 1971. The HL-10 flew from December 22, 1966 until July 17, 1970, and logged the highest and fastest records in the lifting body program. |

| Technician beside the X-24A in wind tunnel testing This photo shows a technician dwarfed beside the X-24A in a full-scale wind tunnel. The X-24A is tan in this photo because it is covered with a simulated ablative coating, which was being investigated as a possible method of protecting vehicles from the heat of high-speed flight. The X-24A was flown 28 times in the program that, like the HL-10, validated the concept that a Space Shuttle vehicle could be landed unpowered. The fastest speed achieved by the X-24A was 1,036 miles per hour (mph--Mach 1.6). Its maximum altitude was 71,400 feet.

| X-24 left instrument & control panel The left instrument and control panel in the cockpit of the Martin Marietta X-24A lifting body research vehicle. Built by Martin Aircraft Company, Maryland, for the U.S. Air Force, the X-24A was a bulbous vehicle shaped like a teardrop with three vertical fins at the rear for directional control. It weighed 6,270 pounds, was 24.5 feet long and 11.5 feet wide (measuring just the fuselage, not the distance between the tips of the outboard fins). Its first unpowered glide flight was on April 17, 1969, with Air Force Maj. Jerauld Gentry at the controls. Gentry also piloted its first powered flight on March 19, 1970. |
