Zipper-Bag Airplane (1958)
Airplanes that can be stowed away between trips, like camping equipment, may be a common sight in the world of tomorrow. They could be folded up like tents, then spread out and inflated to shape.
The secret lies in a new kind of fabric being developed by Goodyear Aircraft Corporation. This material has a network of internal threads connecting the outside surfaces - the longer the threads, the greater the distances between those surfaces. Varying thread lengths could thus make possible any kind of shape, strong enough to be flown when inflated. Rubberizing makes the fabric airtight.
Flying machines constructed of this "cloth" have already been successfully test.
