Glider snatch pick-up
Glider snatch pick-up (GSPU) was a technique used by the Allies of World War II to launch a military glider with a low-flying powered aircraft (the tow or tug), which did not have to land. The snatching aircraft, typically a Douglas C-47 Skytrain ("Dakota"), had a 20 ft (6 m) arm hanging down at a 45-degree angle, supporting a hook at the tip.
