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
