The D-2 had been turned down by the Air Force a number of months earlier because it lacked adequate airspeed and fell short of other military requirements.
The group of officers spent a day at the Culver City plant, before being flown by Hughes to the secret airfield for inspection of his D-2 prototype. The team, of course, visited other aircraft companies as part of the selection process before returning east.
Test flights of the D-2, took place during the month of May 1943, revealing a number of un-resolvable stability problems. When it became clear that the problems could not be solved, Hughes abruptly abandoned the project. A fire then, under mysterious circumstances, destroyed the hanger along with the plane. The official report stated that lightening was the probable cause of the fire.
Hughes made sure that all evidence of the project disappeared from the site including ashes, charred pieces of wood and metal, foundations, utility lines and other structures – all hauled to a secret burial site somewhere out on the desert.
