– United Kingdom “Dakota Rest and Rooftop Johnson”
A Railway Air Services Douglas C-47A-10-DK (DC-3), registration G-AGZA, operating a domestic scheduled passenger flight from London-Northolt Airport (NHT/EGWU), United Kingdom, to Glasgow-Renfrew Airport, United Kingdom, was unable to gain height shortly after takeoff and landed on top of a house at 46 Angus Drive in the London suburb of Ruislip, London, UK.
The airplane sustained substantial damage. The four crew members and one passenger survived.
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.
“The pilot taking off when the aircraft was almost entirely covered with snow. In doing this the pilot committed an error of judgement.”
