Above you can watch the plane's debut, as pilots "Tex" Johnson and James Gannett roll the plane to show off to the crowds (and Boeing's president, William Allen).
As you can probably infer from our recent coverage of EAA AirVenture Oshkosh, this time of the year is prime for Air Shows. This last weekend was Seafair 2012, the modern variant of the Gold Cup Hydroplane Race, which thankfully still includes hydroplane racing but also adds the latest in maritime and aviation displays. Catch it next year, when Seafair begins with a Boeing-sponsored "Parade of Flight" on July 31, 2013. Or hey, see the real thing (still in those snazzy colors pictured above) within the Smithsonian's Steven F. Udvar-Hazy Center right at Washington-Dulles International Airport (IAD).
