http://en.wikipedia.org/wiki/Glider_Pilot_Regiment
The man behind this concept was Colonel George Chatterton, a charismatic leader and a ruthless disciplinarian. His experience as a pre-war RAF fighter pilot and subsequently an infantry officer fitted him well to the task of turning highly trained determined soldiers into skilful pilots. The motto of the Regiment was "Nothing is Impossible".
Among the types developed were the 28 trooper Airspeed Horsa and the 7 ton capacity General Aircraft Hamilcar cargo glider. The General Aircraft Hotspur was used for training the pilots who formed the Glider Pilot Regiment.
The Horsa gliders were capable of carrying 28 fully armed and equipped airborne soldiers, or a Jeep and trailer or gun. They greatly enhanced the mobility and force of the otherwise lightly armed airborne troops. A larger glider, the Hamilcar, could even carry a seven ton tank. A smaller American glider, the Waco CG-4A, officially called the Hadrian by the British, but "Waco" by the pilots and soldiers, was used in Sicily and in Burma. The Waco's steel frame was better suited to jungle operations than the wooden Horsa.
The advantage of the glider was that it could deliver an airborne platoon with all its equipment to a precise spot, day or night, to achieve surprise. The most spectacular example of this was the capture of the Orne bridges in Normandy on D Day. A similar number of men dropped by parachute would be spread over a large area. Gliders also carried the heavier equipment of the Parachute Regiment, Royal Artillery and Royal Engineers. The most famous actions were the taking of the Pegasus Bridge during the invasion of Normandy, Operation Dragoon (the invasion of southern France), Operation Market Garden (Arnhem) and Operation Varsity (Crossing of the Rhine). Out of the 2,596 gliders dispatched for Operation Market Garden, 2,239 gliders were effective in delivering men and equipment to their designated landing zones.
Massed airborne landings at Sicily, Normandy and Arnhem achieved success but at great cost. The Airborne Forces at Arnhem did not lose the battle, they were ordered to hold for two or possibly three days, they held out for eight days. The Regiment's casualties were the highest at Arnhem, 90% were killed, wounded or taken prisoner of war.
