The Boeing Pad Abort Test (also abbreviated to Boe-PAT) was a test of the Boeing CST-100 Starliner and its abort motors, conducted by Boeing as part of NASA's Commercial Crew Program. It was the first flight of Starliner and one of the last milestones ahead of OFT. The mission's main objective was to demonstrate that Starliner could safely pull a crew away from the pad in the event of an emergency prior to liftoff.

After a successful launch, only two of three main parachutes deployed. Despite this, NASA and Boeing deemed the test a success, as Starliner was designed to function on two parachutes if necessary.
