Only 10 copies of the Boeing Model 40C were built. Originally used as mailplanes, they later carried passengers. In 2008 Addison Pemberton, in this restored 40C, and two other pilots in vintage mailplanes re-created the cross-country airmail routes of the 1920s.

Photographer Lyle Jansma started creating 360º views of cockpits in 2005, and has documented historic aircraft in several collections, including the Heritage Flight Museum, Museum of Flight, Tillamook Air Museum, Evergreen Air & Space Museum, and the National Museum of the Air Force. A full set of his cockpit views is available on the ACI Cockpit360º App for iPads and iPhones. Keep visiting this site (airspacemag.com/cockpits) as we add to the gallery below.
