The engineers of the Boeing company in Seattle have a workman-like knack for adapting new technologies, and interpreting specifications with foresight and imagination, and quietly coming up with trend-setting aircraft. When Boeing's original Model 40 mailplane, with wooden fuselage and aging Liberty engine, failed to win a Post Office mailplane contract in 1925, the design languished for about a year. Boeing designers resurrected the Model 40 with a welded steel tube fuselage and a brand-new radial Pratt & Whitney Wasp powerplant. With this amalgamation of technologies, the Boeing Air Transport company was able to bid with confidence on an airmail route with the new Model 40. Its lightweight radial engine saved enough on the scales to allow for incorporation of a small cabin in the fuselage for two passengers. Modest by today's standards, the Model 40 was right on the money for 1927, and set airmail standards until superseded by another Boeing design that embraced technology — the all-metal, cantilever-wing monoplane Model 247 of 1933.
