Crew Access Tower Stacking Passes Midway Point


The steel lattice column that will become the Crew Access Tower for Boeing’s CST-100 Starliner spacecraft continues its methodical rise at Space Launch Complex-41 where four of seven sections of the tower have been stacked.

Built four miles south, each section or tier, is being trucked to United Launch Alliance’s Atlas V launch pad where a crane lifts it into position. The tower will reach about 200 feet high when it’s finished.

Even after stacking is complete, the team will have plenty to do to outfit it for launch, including installing the elevator, white room, crew access arm and infrastructure lines. Since SLC-41 remains an operational facility while the tower is built, work on the tower is taking place between Atlas V launch operations.
