The Launch Team is “Go” for Launch, T-4 Minute Hold Complete

Launch conductors have completed their polls of the launch teams. The T-4 minute built-in hold has been released and the countdown has resumed. The Starliner spacecraft has been configured for terminal count. Three seconds before launch, the Atlas V booster's RD-180 engine will ignite.

Starliner has been switched to internal power and configured for launch. The crew access arm has been stowed for launch. Weather still looking good.
