SpaceCub was a design project for a homebuilt rocket. Between 1993 and 1994, Geoffrey A. Landis proposed that a vehicle designed to launch to the edge of space might be a feasible project for a "personal" spaceship, the equivalent of a Piper Cub for space. The insight was that a flight to "only" 100 km would reach the officially defined edge of space, and even though this is much easier a challenge than an orbital flight, such a suborbital flight would be of excitement to the public, and the pilot would be officially qualified as an astronaut.
SpaceCub was a design project for a homebuilt rocket. Geoffrey A. Landis proposed in 1993-1994 that a vehicle designed to reach the edge of space (around 100 km) could be a feasible "personal" spaceship, similar to a Piper Cub for flight. This idea was based on the fact that reaching this altitude would qualify the pilot as an astronaut and generate public excitement.
