Kit #AA2014. 1/72 scale. Highly-detailed resin kit with decals. In 1962, NASA started a program to build a lightweight, powerless lifting body. The M2-F1 prototype was developed to study the wingless vehicle concept, to demonstrate the ability of pilots to maneuver in the atmosphere, and safety land after reentry from space. The success of the M2-F1 program led to NASA's development of two heavyweight, powered lifting bodies, the Northrop M2-F2 and HL-10. Designation "HL" stands for "horizontal landing". First powerless glide flight was drop-launched from B-52 in January 1966. It was then modified for powered flight in December 1966. In February 1970, a U.S. Air Force test pilot reached Mach 1.86, setting a record for the fastest lifting body flight. In that year, the Space Shuttle was proposed and the HL-10 was selected to test the powered-landing program for NASA Shuttle. After completing 37 flights in July 1970, the HL-10 was retired and stored in Dryden Flight Research Center. To the general public, the HL-10 was probably best known as the aircraft that crashed with astronaut Colonel Steve Austin in the opening sequence of television's "The Six Million Dollar Man".
