The gliders used in #14 were single or two seaters.
Much heavier gliders had been used AT NIGHT and WITHOUT LIGHTS to land, close to each other and their target on 6th June 1944 ( see Pegasus Bridge for more details).
If you really need an aeroplane for the comparison... Have a look at TACA110, an almost new B737-300 which HAD to be a glider and landed on the levee close to New Orleans on 14th. May 1988. Some days later it was flown away. It appears to have been retired, only quite recently in 2016, having worked a full life.
