An "ear-witness" heard the plane overfly her house, the last few seconds of its trajectory, with a high pitch engine noise and several 'backfire' sounds, before the final thump noise.
They tried to locate it in the surrounding fields, but it was snowing and low visibility, and passed by a few times 20ft or so away, without finding it (so I presume no post impact engine fire - not implying fuel starvation)
