Starliner returned autonomously in early September. Since then, NASA and Boeing have been reviewing data from the test flight. (Unfortunately, the errant thrusters were located on the service module of the spacecraft, which is jettisoned before reentry and was not recovered.)

Five thrusters in the service module shut off during the approach towards the station, prompting the astronauts to manually take control as they held Starliner at a safe distance from the ISS.
