The Messerschmitt Me 321 was designed to be a glider to supply troops during invasions. It was to carry a company of troops, a gun, or a tracked vehicle.
The Me 321 was made of welded steel tube and fabric or plywood covering.
There were rockets that assisted with takeoff.
Initially the pilot had to be very strong to control the glider as there were no assistants and no power. Later there was a crew of three.
