On September 8, 1970, Trans International Airlines Flight 863, a Douglas DC-8 N4863T ferry flight, with eight flight attendants and three cockpit crewmembers on board, crashed en route from John F. Kennedy International Airport in New York City to Washington Dulles International Airport. Unknowingly to the crew, a foreign object became wedged between the right elevator and horizontal stabilizer, blown there by backwash from the aircraft preceding it on the taxiway. The problem was not detected, and the aircraft crashed upon takeoff with the loss of all 11 on board. Following this incident, the FAA instituted new minimums between aircraft in line-up for take-off.
