Allegheny Airlines Flight 604

Flight 604 departed from runway 09 at Williamsport Regional Airport when personnel in the airports control tower noticed smoke trailing from the right engine. This was immediately relayed to the flight crew in response captain Lauber transmitted "Flight 604 is coming back in, ... we've got the right engine feathered." Tower then asked what was the desired runway and it was determined they'd enter the pattern and land runway 09. Tower gave flight 604 to do this, captain Lauber replied "Okay". Several witnesses on the ground observed the flight remain south of runway 09/27 center line. Several airport workers and other witnesses saw fire and smoke trailing the right wing and observed the aircraft climbing slightly. The aircraft was in a nose high attitude but in a shallow climb. After the tower received the captains transmission further attempts to communicate with the flight were unsuccessful. An aircraft mechanic at the airport estimated to aircraft to be at 500 ft above the runway threshold of the 27 end of runway 09/27. The aircraft continued in a northeasterly direction. A witness in her yard estimated the aircraft to be 700 to 900 feet above her house when it passed overhead and disappeared beyond a ridge. The women then said she heard to propeller noise soften to silence prior to an explosion sound.[4][5]

The aircraft initial impact was upward on a hill at an elevation of 1,100 msl. The aircraft bounced several times, the left wing was ripped off 38 feet from the tip by a telephone pole, the right wing was ripped off 24 feet from the tip after digging into the hill. The aircraft then slid down a steep hill and caught fire after coming to rest. Passengers and crew evacuated via a tear in the fuselage between the cockpit and cabin. Flight attendant Barbara Creske led the evacuation helping captain Lauber who suffered low body injures outside to fuselage. Creske also aided multiple injured passengers evacuate. 8 minutes after impact the right wing and cockpit were fully engulfed in fire. Emergency personnel were on scene within 5 minutes.[6]

Of the 40 passengers and crew, 23 were injured; 11 seriously. Common injuries included leg, neck and back injuries. One man's arm was severely burned when trying to aid in the rescue effort. All 40 occupants survived the accident.
