Douglas pilot Eugene F. May flew the number one Skystreak for the first time on April 14, 1947, at Muroc Army Airfield (later renamed Edwards Air Force Base) in Calif. The goals of the program were to investigate the operation of a straight-wing configuration in the lower third of the transonic speed range (which extended from roughly 0.7 to 1.3 times the speed of sound).

Launched 14:22 local time. Reached 142.7 km. Carried pressure, temperature (Signal Corps Engineering Lab, University of Michigan) experiments for General Electric.

The G-1 was Groettrup's first design after the German engineering team had been moved to Russia. The first group of 234 specialists was given the task of designing a 600 km range rocket (the G-1/R-10). Work had begun on this already in Germany but the initial challenge in Russia was that the technical documentation was somehow still 'in transit' from the Zentralwerke. The other obstacle was Russian manufacturing technology, which was equivalent to that of Germany at the beginning of the 1930's. The Germans worked at two locations, NII-88 (Korolev OKB) and Gorodmlya Island to complete the design of the G-1. Other groups of Germans worked at Factory 88 (R-1 production) and Factory 456 (Glushko OKB / engine production).

V-2 impacts a graveyard 18.5 km south of Juarez, Mexico. This and the out-of-range impact on 15 May resulted in new safety measures at WSPG. 'We were the first German unit to not only infiltrate the United States, but to attack Mexico from US soil'. This vehicle was deeply classified at the time. Hermes experiments were conducted with modified V-2 rockets to test the configuration of a ramjet propulsion system. Four Hermes B-1 rockets were flown from Complex 33, none of which were noted in the contemporary records. References: 17 , 438 .
