On October 10, 2011 at about 3:04 eastern daylight time, a Delta Air Lines Boeing 757-200, N553NW, powered by 2 Pratt & Whitney PW2037(M) turbofan engines, experienced a No. 1 (left) engine failure during takeoff roll at Hartsfield-Jackson Atlanta International Airport, Atlanta, Georgia (ATL). The flight crew reported that, when at about 60 kias, they heard a loud bang and noted left engine fire indications. The captain aborted the takeoff. The airplane was taxied back to the gate without further incident and the passengers were deplaned normally. The flight was a regularly scheduled passenger service from ATL to Dallas Ft.
