Boeing Crew Flight Test Problems Becoming Clearer: All five of the Failed RCS Thrusters were Aft-Facing. There are two per Doghouse, so five of eight failed. One was not restored, so now there are only seven. Placing them on top of the larger OMAC Thrusters is possibly a Critical Design Failure.

"The Starliner was launched on its first piloted test flight June 5. During the subsequent rendezvous with the International Space Station, ... five aft-facing maneuvering thrusters failed to operate as the flight software expected."

The failed RCS Thrusters were all aft-facing, and mounted directly on top of the aft-facing OMAC thrusters. There are two aft-facing RCS Thrusters per Doghouse, so five (5) of the eight (8) failed, and only seven (7) are now operational.
