NASA has been working on similar concepts for years. The Eclipse Tow
Launch Demonstration Project actually towed an F-106 behind a C 141 in
1998. http://www.nasa.gov/centers/dryden/p...S-049-DFRC.pdf

This was to validate the Kelly Space and Technology Eclipse Astroliner
Tow-Launch Concept which featured a low aspect ratio rocket glider as a
launch vehicle towed behind a (guess what), 747.
