The NTSB Friday announced that information retrieved from the Colgan Air Bombardier Q400 Dash 8 that crashed after a near vertical descent into a suburban Buffalo neighborhood indicates the crew was aware of "significant ice buildup" on the aircraft. Steve Chealander, speaking for the NTSB, Friday told reporters that the cockpit voice and flight data recorders were recovered in good condition and showed the crew noted significant icing on the wings and windscreen as the aircraft descended through 11,000 feet -- and after the aircraft's de-icing equipment had been switched on. The NTSB has not confirmed de-icing equipment was functioning. Initial details of the crash's timeline show that one minute before impact, while flying at about 2,000 feet, the crew lowered the landing gear.
