The report provides the details of a full-scale crash test of a large transport aircraft. The purpose of the test was to obtain crash environment data of the test aircraft and the various experiments installed aboard the aircraft. The special experiments consisted of military crew and commercial passenger seats, cargo restraint systems, postcrash locator beacons, baby and child restraint systems, radioactive material containers, a military litter system, and provisions for emergency lighting. The test involved a Lockheed Constellation Model 1649A aircraft, which was guided into a series of crash barriers with a monorail nose gear guidance system. Initial impact occurred against barriers which removed the landing gear, permitting the airplane to become airborne until the moment of impact with the wing and fuselage crash barriers. The wing fuel tanks were ripped open by the wing barriers, allowing simulated fuel to spill out in a heavy mist during the crash sequence. The fuselage was broken in two places during the crash, just aft of the cockpit between fuselage stations 370 and 380 and just aft of the galley between fuselage stations 1020 and 1030. Peak longitudinal accelerations on the order of 25G's were measured at the cockpit floor when the aircraft impacted the 20 degree slope. Most of the onboard experiments remained in their relative locations throughout the test.
