The Cornelius XFG-1 Fuel-Tank Glider was and interesting concept aerodynamically and functionally. Aerodynamically it was a non-powered glider with forward swept wings and no horizontal tail plane. The incidence of the wings could be changed on the ground between 3 degrees and 7 degrees. These aircraft were actually built and were flight tested during World War II.
The purpose of this experimental aircraft included in-flight refueling of the mother aircraft (transport or bomber) to top off the tanks before entering enemy airspace (thus extending the range of missions). The glider would be cut loose and land for re-use.
Another idea was to fly the gliders unmanned to serve as an expendable drop tank. Yet another proposed use was to use the gliders to deliver fuel to troops on the ground behind enemy lines. The glider pilot would join up with the infantry.
