The Frankfort Cinema is a sailplane manufactured in the United States in the 1930s and 1940s and which was used by the United States Army Air Corps as a training glider under the designation TG-1. It was a high-wing, strut-braced design with a fully enclosed cabin. Originally designed as a single-seater, a two-seat version designated the Cinema II was produced soon afterwards, and this design was put forward when the Army issued a requirement for training gliders. At the same time, the company was awarded production contracts for transport gliders, the CG-1 and CG-2.
