During the preparation for a possible invasion on Britain during World War II (called Operation Sealion), the Oberkommando des Heeres (OKH) required a cargo glider that would carry about 130 equipped soldiers because it was not possible to ship all the important weapons and goods by naval vessels. Cargo gliders were also needed to secure bridgeheads in a short time. The capture of Fort Eben-Emael was, for the German army leaders, the proof that gliders are crucial for these scenarios.

However, the Me 321 glider was ultimately so heavy that she needed to be towed by three Messerschmitt Me 110 fighters, which was a waste of much-needed combat aircraft.

The German web site WaffenHQ.de serves pictures and a lengthy description of the Me 321 glider.
