. Once released from the tow craft near the front, they were to land on any convenient open terrain close to target hopefully with as little damage to this cargo and crew as possible as most landing zones (LZ) were far from ideal. The one-way nature of the missions meant that they were treated as disposable leading to construction from common and inexpensive materials such as wood.

Troops landing by glider were referred to as air-landing as opposed to paratroops. Landing by parachute caused the troops to be spread over a large drop-zone, whereas gliders could land troops in greater concentrations precisely at the target landing area. Furthermore, the glider, once released at some distance from the actual target, was effectively silent and difficult for the enemy to identify. Larger gliders were developed to land heavy equipment like anti-tank guns, anti-aircraft guns, small vehicles, such as jeep

s had replaced gliders. Helicopters have the advantage of being able to extract soldiers, in addition to delivering them to the battlefield. Also, advances in powered transport aircraft were being made, to the extent that even light tanks could be dropped by parachute.

Development

The early sporting objectives of gliders were quickly overtaken in the Soviet Union and in Germany by military applications, mainly the training of pilots. By 1934 the Soviet Union had ten gliding schools and 57,000 glider pilots had gained licences.

In 1932 the Soviet Union demonstrated the TsK Komsula, a four-place glider, designed by GF Groschev that could also be used for cargo. Larger gliders were then developed culminating in an 18-seater at the military institute in Leningrad

He reported back to his superiors in Berlin details of a 1,500 man parachute drop and the large transport gliders that he had seen. The Luftwaffe opened a parachute school as a result in 1937. Further field testing convinced Student that a vehicle was needed to deliver the heavy weapons for the lightly armed parachute troops. This idea was dismissed until October 1938 by which time Student had risen to major-general and was appointed Inspector of Airborne Forces.

s. Ten gliders landed on the grassed roof of the fortress. Only twenty minutes after landing the force had neutralized the fortress at a cost of six dead and twenty wounded. Hitler was anxious to gain maximum publicity and so several foreign attachés were given guided tours of the fortress. Consequently the British, American and Japanese became quickly aware of the methods that had been used. By mid-1940 both Japan and Britain had active glider programs.

Development then began of even larger gliders such as the Gotha Go 242

.

Gliders were also used by Germany in Greece in 1941. On April 26, 1941 the troops from six DFS 230 gliders captured the bridge over the Corinth Canal accompanied by 40 plane-loads of German paratroopers. (Fortuitously the British were able to demolish the bridge a few hours later.) Next General Student then convinced Hitler that Crete could be captured using only airborne troops.Consequently on May 20, 1941 500 German transport aircraft carrying paratroopers and 74 DFS 230 gliders took off from the Greek mainland. During the capture of the island 5,140 German airborne troops were either killed or wounded out of the 13,000 sent. Among the 350 German planes destroyed in the operation, half had been Ju52s which seriously depleted the force needed for the invasion of the Soviet Union shortly after. As a result Hitler vowed never to use his airborne force in such large numbers again.

Some German glider operations continued later in the war, some examples being the rescue operation

The Soviet Union built the world's first military gliders starting in 1932, including the 16-seat Grokhovski G63, though no glider was built in quantity until World War II. During the war there were only two light gliders built in series: Antonov A-7
