THE SKED AIR CARRIER FLT WAS ABORTED AFTER THE CAPT HEARD A NOISE AND FELT A VIBRATION EMANATING FROM THE LEFT SIDE OF THE ACFT, WHICH AT THE TIME, WAS PERCEIVED AS A 'BLOWN' TIRE. THE ACFT WAS SUBSEQUENTLY STOPPED ON THE ACTIVE RWY, AND AN ORDER FM THE CAPTAIN TO REMAIN SEATED WAS GIVEN. THIS ORDER WAS ALMOST IMMEDIATELY RESCINDED WHEN IT WAS LEARNED, THROUGH A VISUAL SIGHTING, THAT THE LEFT ENG WAS ON FIRE. THE CAPTAIN ISSUED A FIRM ORDER AND EVACUATION OF THE PAX WAS INITIATED. THE SMOKE FROM THE LEFT ENG PROHIBITED PAX USING THE OVERWING EXITS FROM DEPLANING IN THE PRESCRIBED MANNER. THE PAX WHO WERE SERIOUSLY INJURED WERE KNOWN TO HAVE JUMPED FROM THE FRONT OF THE WING INSTEAD OF USING THE WING FLAP, WHICH ACTS AS A SLIDE OFF THE REAR OF THE WING. EXAM OF THE LEFT ENG REVEALED FAILURE OF THE 4TH STAGE TURBINE SECTION.
