A commercial airliner crashed into a house and burst into flames late yesterday outside Buffalo, New York, killing at least 50 people, according to DPA. The dead included 49 people on Continental Connection Flight 3407 and one person on the ground, officials said Friday. The fire was so intense that investigators were unable to approach the crash site early Friday morning. They subsequently managed to recover the cockpit voice recorders from the tail of the aircraft. The crash took place at 10:17 pm (0317 GMT Friday) in the village of Clarence Centre, about 10 kilometres from Buffalo Niagara International Airport. The 74-seat Bombardier operated by Colgan Air was flying in from Newark, New Jersey. Investigators said today that they had not ruled out any possible causes.
