Here is something else to ponder - Nazi launching first man into space almost 20 years before Gagarin and Shephard
Payload capacity of V2 was about 1000 kg (2200 lbs) and was capable of reaching over 100 miles (160 km( in a vertical flight
feasible could have designed and flown a space capsule on sub orbital hop in late 1943 Hitler vetoed it and Von Braun got in trouble with Gestapo
over supposedly wanting to use V2 to explore space
The REDSTONE which formed base for Jupiter C which launched first US satellites was in reality a cleanup up V2 - ie V2 2.0
As was the Redstone launcher for the suborbital Mercury flights
