General Airbourne Transport Proof of Concept
Around 1942 Bowlus began work on a twin boom flying-wing glider for military transport work In order to test his design he began work on a half-scale proof-of-concept flying model, forming the Airborne Transport Company in Los Angeles, California for the purpose.
Construction of the test model was carried out in his tiny shop, a former dry cleaning shop where there was just sufficient room to build the two-seat open-cockpit prototype. On completion, the glider was flown at Muroc Dry Lake, now the sight of Edwards AFB. The glider flew well and Bowlus and partner Albert Criz set about designing, building and marketing the full-size glider, the XCG-16.
