On display at Planes of Fame Air Museum. This sailplane was built during World War II to train cargo glider pilots. It had a single wheel instead of a skid, and the fuselage had a steel-tube structure, weighing 475 lb empty. The USAAC placed an order for 75, followed by 75 more. These were given the designation TG-4A, but the flight characteristics were quite different to those of a cargo glider. After the war, these "L-K" gliders with a 23:1 glide ratio were used to promote civilian gliding, and some were modified to achieve higher airspeeds.

The Laister-Kauffmann LK-10A Yankee Doodle 2 was designed for training cargo glider pilots. Designated TG-4 by the military, 42-53060 was one of 150 delivered during WWII. All were withdrawn before the end of the war as the flight characteristics of the aircraft were so different to those of a cargo glider (better), the training was not that relevant. Many TG-4s were used by civilian gliding clubs and flyers post war. Donated to the Western Antique Aeroplane and Automobile Museum in 2017, N54632 was restored to flying status by the Spring of 2018.

One of the oldest operational gliders in Canada, this Laister Kauffman LK-10A glider was built in 1943 and was one of 150 built inSt Louis, Missouri for the wartime United States Army Air Corps' glider pilot training program. The aircraft was imported to Canada in 1947 and was part of the fleet of the Rideau Gliding Club in Kingston, Ontario from 1967 to 1990 and later acquired by current owner Herman Ten Cate in February 1995.
