The Goddard P series pump-turbine tests had run from November 1939-October 1941. The series included 15 proving-stand tests and nine attempts at flight tests, of which only two resulted in flights. Average interval between tests was 28 days. This also ended Goddard development of liquid fuel rockets for space flight. Beginning in September 1941 with the impending involvement of the US in the world war, the Goddard rocket establishment worked under contracts with the Bureau of Aeronautics of the Navy Department and the Army Air Forces. Up to that point Goddard's team had completed 103 liquid rocket proving stand tests and made 48 attempts at flight tests, of which 31 resulted in rocket flights References: 482 .
