Test Stand VII at Peenemünde, 15:58 on 3 October 1942: the launch point inside a roughly 100-by-150-metre ring earthwork, with concrete apron, steel firing table, grassy embankment and Baltic coastal pines. The rocket is airborne about 3 m above the firing table, supported mid-ascent by thrust from the operating engine.
