Boeing/United Launch Alliance (ULA) emergency egress system

Commercial Crew astronauts test out the Boeing/United Launch Alliance (ULA) emergency egress system on June 19, 2018, at Cape Canaveral Air Force Station’s Launch Complex 41 in Florida.

The emergency egress system provides an escape route in the unlikely event of an emergency prior to liftoff on launch day.

It will be in place when Boeing’s CST-100 Starliner, launched aboard a ULA Atlas V rocket, carries astronauts to the International Space Station. NASA/Frank Michaux
