On January 14, 1951, the Douglas DC-4 of National Airlines crashed on landing at Philadelphia International Airport.

One of the dead was the lone flight attendant, Frankie Housley, who had gone back into the burning aircraft to try to save more passengers.

On arrival at Philadelphia International Airport, the pilots tried to land the aircraft too far down the runway, instead of aborting the approach.

The left wing broke off, rupturing the gasoline tanks, and the airplane caught fire.

Returning to the cabin, she helped passengers release their seat belts, guided them to the door and gave a gentle shove to those who were hesitant to jump.
