The Lippisch DM-1 has a rather odd history. What started out as a Lippisch project for a supersonic delta fighter powered by a coal-dust burning ramjet engine (Lp 13a) led to a full-scale wooden glider which was being built at FFG Darmstadt until those facilities were bombed. The unfinished D33 was then moved to FFG Munich where the designation changed to DM-1 (Darmstadt-Munich 1) and almost completed as a test glider when US troops arrived. Under Patton, the DM-1 was allowed to continue on in the summer of 1945 towards completion but when finished no German pilot was allowed to fly it off of a Si-204 aircraft for flight testing and no rocket motor was allowed installed for powered flight. The US opted also not to attempt to fly it off of a DC-3. Instead, the entire aircraft was crated in Nov 1945 and shipped to the US where it was placed in the Langley wind tunnel and modified extensively under Dr. Lippisch himself. By the 8th modification the DM-1 was almost a new aircraft with seperated cockpit, modified tail, and heavily modified fuselage. This led to the XF-92A delta and then a range of Convair deltas that included the F-102, F-106, Seadart, and finally the B-58 Hustler!!!
