DC7 Crash Test

This is a brief exerpt from a 15-minute film produced by the FAA in the 1960's. A DC7 was loaded with sensors and its fuel tanks filled with colored water, then sent down a runway filled with obstacles designed to intentionally destroy parts of the aircraft. (Note: This was originally mislabelled as being a DC9, but I've corrected it due to it being brought to my attention by a commenter.)
