Tellingly, perhaps, NASA has only placed firm orders with Boeing for three Starliner flights once the agency certifies the spacecraft for operational use.
Spacecraft 1 was used for testing the launch abort system during the program's Pad Abort Test in New Mexico. Spacecraft 2 [is] being prepared to fly the first people on Starliner's Crew Flight Test. Spacecraft 3 [is] slated for the uncrewed Orbital Flight Test...
During rendezvous with the space station the day after launch, four more leaks developed and five of the ship's aft-facing thrusters did not operate as expected.
five aft-facing maneuvering thrusters failed to operate as the flight software expected. Four were later successfully test fired and one was declared failed.
Resetting and firing the thrusters eventually showed that four of the five were again functioning, and the Starliner docked with the ISS after a delay.
The 44-mile-high perigee, or low point, of the suborbital trajectory is inside Earth's atmosphere, meaning the Starliner would re-enter the atmosphere and come back to Earth without an additional propulsive maneuver.
