Final Departure, Flight 553. On my very first road trip to photograph airliners I spent the day at PIT. Driving home that evening I heard on the radio that a TWA flight from PIT had a mid-air collision with a Beechcraft over Ohio. This is THAT FLIGHT, Flt 553, about to leave the gate at PIT. The aircraft was less than two months old, and I've never seen another photo of it.
