Flight 975 to Orlando was starting its takeoff roll on runway 27-left when the front compressor hub failed and severed the main fuel line in the #2 engine which spewed fuel that ignited. The crew turned onto runway 30 and stopped quickly to evacuate the passengers. The passengers evacuated safely with no fatalities and the ARFF extinguished the fire quickly.
