Boeing has restored the last intact 307, Pan Am Clipper “Flying Cloud” (NC19903), for the National Air and Space Museum of the Smithsonian Institution. This is one of the most extensive and meticulous restorations of an historic aircraft. News of its delivery to the NASM in early August 2003 was widely reported. Photographer Bob Harrington captured scenes of the crash during rebuilding that delayed delivery of the restored aircraft to the NASM. Read more about the crash.

Pan American owned three Stratoliners, while TWA had five. The sixth was owned by Hughes. The first of the 10 Stratoliners — the prototype — was destroyed in a crash.
