Remarks: This is the only remaining Stratoliner. Only 10 were built, of which 3 operated by Pan Am. This one, "Clipper Flying Cloud", was delivered to Pan Am in March 1940. It was restored in 2001 but crashed in Seattle, and had to be completely restored again in 2002. In August 2003 she made her final cross-country trip to be preserved here at the Udvar-Hazy Museum.
Remarks: Of the 10 307's manufactured, this is the last known edition. It has been restored by Boeing volunteer employees, flown to Washington, DC, and retired to the Udvar-Hazy Center in 2003. It is currently being exhibited at the Udvar-Hazy Center of the Smithsonian Air & Space Museum.
