Tells of the TWA Flight 400 airplane disaster at Pittsburgh, Pennsylvania.
Other news of the day. Minor spine wear, otherwise good.
wikipedia notes: On April 1, 1956, a Martin 4-0-4, registration #N40403, operating as TWA Flight 400, crashed on takeoff from Greater Pittsburgh International Airport (PIT). Twenty-two of the 36 people aboard the aircraft, including one crew member, perished in the crash.
Flight 400 was to be an IFR flight to Newark International Airport (EWR) in Newark, NJ. On this particular flight, the first officer was in the left seat, as he was being line-checked by the captain. As the aircraft became airborne, a sharp yaw was experienced while the first officer reduced power at an altitude of approximately 100 feet. Almost immediately, the fire warning light for the number one engine illuminated, however, the fire warning bell never sounded. At this point, the first officer most likely throttled down the number one engine. The captain had only noted the loss of power shown by the BMEP gauge, but never saw the fire warning light. He pulled the mixture to idle cutoff. As the first officer reached for the manual feathering button, the captain stopped him. The captain indicated that the autofeather device would feather the no. 1 prop. This never occurred, due to the throttle lever being retarded to a position aft of the switches that arm the autofeathering system. The no. 1 prop created sufficient drag, causing the aircraft to continue to yaw to the left. At only 1690 feet past the runway's end, the aircraft crashed.
The fire warning appears to have been caused by an exhaust connector clamp failure. Hot exhaust gases were blown directly onto an overheat detector.
Probable cause of the crash has been determined as: "Uncoordinated emergency action in the very short time available to the crew, which produced an aircraft configuration with insurmountable drag."
