A suborbital configuration using a single rocket engine for point to point travel was considered. The design was projected to be capable of stable hypersonic atmospheric flight at speeds up to Mach 22, and will glide to earth like the Space Shuttle.
NASA's X-24B test aircraft is also based on the FDL-7 lifting body.
The ship will use a metal skin that will be more resistant to weather conditions than the Space Shuttle according to Paul Cyzsz, an engineer with the FDL-7 program now with PlanetSpace.
PlanetSpace had indicated[when?] that initial demonstration flights would have to begin in December 2009.
In the event, when funding was not received from NASA, no full design effort was completed beyond the initial conceptual work.
