Because the record flight of August 29, 2006 proved Enevoldson's thesis, Steve Fossett agreed to fund, progressively, the next mission: to build a special purpose sailplane with a pressurized cabin to fly to 90,000 feet. At the time of Steve's death on September 3, 2007, the structural and aerodynamic design of the fuselage had been completed, along with the aerodynamic design of the entire sailplane. Funding for the remainder of the Perlan Project was lost with Steve's death, and a search for new funding was begun.
