The secret space programs could not exist without vehicles that traverse the vast distances between planets and solar systems. Randy Cramer demonstrates that humanity is one of the more creative species as evidenced by the number of different types of spacecraft humans use. Each kind is ideally suited for different operations such as: fighters, shuttles, carriers, destroyers and Juggernauts. He also describes some E.T. craft such as mother ships, scout crafts and planet sized ships capable of providing for entire civilizations, over the course of centuries.
