NASA Dryden Flight Research Center Towed Glider Air-Launch Concept would use a glider that would be towed to an altitude of 40,000 feet by a large transport aircraft such as a 747. A rocket would be slung under the belly of the glider and launch after the craft reached its desired altitude." Link to Original Source
The most difficult thing in the world is to know how to do a thing and to
watch someone else doing it wrong, without commenting.
