The aircraft was an experimental machine fitted with a pressurised cabin for high-altitude recconnaisance operations. On Sunday, 12 July 1942, W5795 was having its cabin pressurisation systems checked; whilst cruising at 32500 feet, a section of one of the propeller blades sheared off, penetrating the cabin, causing loss of pressure and possibly incapacitating the pilot. The aircraft broke up during its dive to earth, debris falling over a wide area between Derby and Ilkeston. Sadly, there were no survivors.
