Which facility was the world's first long-range guided ballistic missile tested at?
Test Stand VII Test Stand VII (German: "Prüfstand VII" , P-7) was the principal V-2 rocket testing facility at Peenemünde Airfield and was capable of static firing of rocket motors up to 200 tons thrust. Notable events at the site include the first successful V-2 launch on 3 October 1942, visits by German military leaders, and Allied reconnaissance overflights and bombing.
National Transonic Facility (Hampton, Virginia) The National Transonic Facility (NTF), also known internally as facility 1236, is a high-pressure, cryogenic, closed-circuit wind tunnel at the Langley Research Center in Hampton, Virginia. It uses nitrogen gas, at high pressure, to cool the air which allows flight aerodynamics to be duplicated in small scale. The cross section of the tunnel is 8.2 ft high and 8.2 ft wide. Unlike full-scale wind tunnels, the NTF can adjust airflow to match any model size down to 1/50 scale. The facility can operate liquid nitrogen is sprayed into the circuit or at ambient air temperature.
