The $4.2 billion CST-100 Starliner was first conceived in 2010, built on a long legacy of designing and building spacecraft for Apollo. The spacecraft measures 14.8 feet (4.5 meters) across and can fit up to seven astronauts, and is around the same size as the Dragon crew capsule.

Unlike SpaceX’s Dragon spacecraft, however, Starliner has traditional hand controls and switches, as well as touchscreens. The Crewed Flight Test (CFT) will carry NASA astronauts Butch Wilmore and Suni Williams on board Starliner.
