AFTER FLT 99 WAS CLEARED FOR TAKEOFF, THE AIRCREW OF FLT 199 STARTED THEIR ENGINE, BUT IT TORCHED AND EMITTED FLAMES FROM THE TAIL CONE. THE CAPTAIN OF FLT 25 SAW THE FLAMES AND TRANSMITTED ON TOWER FREQUENCY, "99, YOU'RE RIGHT ENGINE'S ON FIRE." AT ABOUT THAT TIME, UNITED FLT 99 HEAVY WAS LIFTING OFF. THINKING HE HAD AN ENGINE FIRE, THE CAPTAIN OF UNITED FLT 99 HEAVY ABORTED ABOVE V1/VR RATHER THAN CONTINUING INTO A LOW CEILING WITH FOG AND RAIN.
