The CG-9 was a large transport glider of twin-boom configuration with a seating capacity for 32 troops. The central fuselage nacelle sat 20 troops, while the outboard nacelles each carried six troops. Ordered on 27 June 1942, the two prototypes, given serials 42-56697/56698, were not completed, although a mock-up had been completed and had been inspected. At the time of cancellation, on 2 December 1942, the static test airframe was 55% completed, the first aircraft 5% complete and the second aircraft only 1% complete.[1]
