The Crew Access Arm, or CAA, and White Room for Boeing's CST-100 Starliner is transported past the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. It is on its way to Space Launch Complex-41 at Cape Canaveral Air Force Station where it will be attached to the Crew Access Tower. The CAA will be serve as the connection that astronauts will walk through prior to boarding the spacecraft when stacked atop a United Launch Alliance Atlas V rocket. This completes the major construction of the first new Crew Access Tower to be built along Florida's Space Coast since the Apollo era. Under a Commercial Crew Transportation Capability (CCtCap) contract with NASA, the Starliner system will be certified by NASA's Commercial Crew Program to fly crews to and from the International Space Station.
