The performance characteristics of a preformed elliptical parachute at altitudes between 200,000 and 100,000 feet have been obtained by means of in-flight photography. It was demonstrated that this type of parachute will open at altitudes of about 200,000 feet if conditions such as twisting of the suspension lines or draping of the suspension lines over the canopy do not occur. Drag-coefficient values between 0.6 and 0.8 were found to be reasonable for this type of parachute system in the altitude range between 200,000 and 100,000 feet.
