It was a cold, snowy evening at London-Northolt Airport, when the DC-3 taxied into position for takeoff. The snow storm had closed the airport to incoming traffic, and outbound traffic was subject to long delays. The plane had been waiting for more than an hour waiting for clearance. When G-AGZA received clearance, the pilot ran the engines up to 45.5 inches of manifold pressure and 2,500 RPM. The DC-3 lifted off the runway but couldn't gain height. The aircraft landed on top of a house at 46 Angus Drive in the London suburb of Ruislip.

Probable Cause:

PROBABLE CAUSE: "The pilot taking off when the aircraft was almost entirely covered with snow. In doing this the pilot committed an error of judgement."
