'Ice build-up' on crashed plane

The crew of a plane that crashed in New York state killing 50 people noticed "significant ice build up" shortly before it crashed, investigators say.

Analysis of data recorders recovered from the scene shows the plane made a series of severe pitches and rolls seconds before plunging into a house.

Continental flight 3407 was minutes from Buffalo airport when it crashed at 2210 (0310 GMT) on Thursday.

Investigators are working to recover victims' remains from the site.
