One of the key objectives of the Starliner Orbital Flight Test is a separation from the ULA Centaur second stage booster rocket. This video shows the successful separation of Starliner from Centaur after the Dec. 20 launch. It’s one of several test objectives completed so far during this mission. This event was prior to the Mission Elapsed Timing anomaly that prevented Starliner’s orbital insertion burn, which kept the spacecraft from docking with the International Space Station.
