The flight set the Absolute Altitude Record for gliders at 15,460 metres (50,720 ft).[41] Since the glider cockpit was unpressurized, the pilots wore full pressure suits (similar to space suits) so that they would be able to fly to altitudes above 45,000 feet (14,000 m). Fossett and Enevoldson had made previous attempts in three countries over a period of five years before finally succeeding with this record flight. This endeavor is known as the Perlan Project.
