Stock Photo - Aboard a truck and ready for a test flight is the Paresev 1_C on the ramp at the NASA Flight Research Center, Edwards, California. The half_scale version of the inflatable Gemini parawing was pre_flighted by being carried across the Rosamond dry lakebed on the back of a truck before a tow behind an International Harvester Carry_ All. The inflatable center spar ran fore and aft and measured 191 inches, two other inflatable spars formed the leading edges. The three compartments were filled with nitrogen under pressure to make them rigid. The Paresev 1_C was very unstable in flight with this configuration.
