The US military has built and tested a range of ultra-lightweight gliders made of plywood. They are designed to be released from a conventional aircraft at 25,000ft and can be used to drop as much as 1,800 pounds of cargo to US troops. California-based Logistic Gliders says it would be able to move goods up to 70 miles away. GPS allows the gliders to navigate autonomously and their wings fold out and in automatically. It drops to the ground via a parachute and a reinforced honeycomb cardboard nose prevents damage on landing.
