The BBC video is blocked. The Horsa with those big flaps would really come down. Better than the Waco CG4As. My folks had a friend who was a glider troop. He was training in the the northeast US somewhere when the war ended. He told me that during training he never "landed" in a glider. They were always destroyed when they came to a stop. He wasn't looking forward to actually being in a combat landing. Have you see this video?
