This clip: Extreme Long shot of impact showing the huge fireball surrounding the airplane. With narration. Background: On December 1st, 1984, a remote controlled 4 engined transport jet took off from Edwards AFB, CA and crashed into a barren patch of nearby desert. This Controlled Impact Demonstration was a joint R&D program by the FAA and NASA. The FAA designed the C.I.D. to underscore results of exhaustive research in two areas of aircraft safety: improved crash protection and reduced post-crash fire hazards.Despite the fact the crash did not go exactly as designed C.I.D.did achieve its primary objectives.The analysis of C.I.D. data continues. The CID's crash wothiness tests were as important to the FAA as the fire safety tests. The crash protection objectives were: 1st: To obtain data on impact forces and their transmission thru the structure to the seats and occupants. 2nd: To evaluate the performance of existing and advanced energy absorbing seats. 3rd :To compare tests used to predict structural behaviour with an actual crash. AMK (anti-misting kerosene) fuel was employed in the test. The FAA has examined AMK's potential for protecting commercial transports from ignition of misted fuels. All research indicated that AMK would be effective in preventing this problem. The C.I.D. was an opportunity to use AMK in a realistic, impact-survivable crash.
