NASA's Reduced Gravity Program provides the unique weightless or zero-G environment of space flight for testing and training of human and hardware reactions. NASA used the turbojet KC-135A to run these parabolic flights from 1963 to 2004.

History
Witness the test flight of the TU-144LL, 1998
Witness the test flight of the TU-144LL, 1998The Russian Tu-144 was modified by the Tupolev Aircraft Design Bureau of Moscow into the TU-144LL Flying Laboratory; the TU-144LL is seen here in tests from 1998. Together with U.S. partners NASA and the Boeing Company, the TU-144LL was used to gather data to help in the design of more-efficient and environmentally friendly next-generation supersonic transports.

Tupolev Tu-144, world’s first supersonic transport aircraft, designed by the veteran Soviet aircraft designer Andrey N. Tupolev and his son Alexey. It was test-flown in December 1968, exceeded the speed of sound in June 1969, and was first publicly shown in Moscow in May 1970. In its production model the Tu-144 was 65.7 metres (215.6 feet) in length, with a wingspan of 28.8 metres (94.5 feet). Its normal cruising speed was up to Mach 2.2, more than twice the speed of sound. Among its notable features were the “double-delta” swept-back wings, the “moustache” foreplanes that pivoted out from the fuselage just aft of the flight deck to improve flight characteristics during takeoff and landing, and the nose section that could be “drooped” downward to improve the crew’s line of vision during takeoff and landing.

The aircraft had an inauspicious start when the first production Tu-144 crashed at the 1973 Paris Air Show. The aircraft was put into commercial service on the Moscow–Alma Ata route, flying mail (1975) and then passengers (1978), but the planes were pulled from service following another crash in 1978. Later models continued to fly as test beds for the technology of supersonic flight.
