On December 1, 1984, NASA and the Federal Aviation Administration (FAA) conducted the Controlled Impact Demonstration, where they deliberately crashed a Boeing 720 aircraft with the intent of improving occupant crash survivability. Seen left-to-right, top-to-bottom, the plane makes a practice approach, hits the ground, slides for a short distance, strikes posts cemented in the ground, and becomes engulfed in flames.Photos: NASA
