Tier Two
From Wikipedia, the free encyclopedia
Tier Two is Scaled Composites and Virgin Galactic's orbital human spaceflight program. The program's spacecraft will be based on SpaceShipTwo if that is successful. Initial plans call for the spacecraft to be named SpaceShipThree.
Speculations abound on whether they will attempt to qualify SS3 for America's Space Prize.
