Not all plain sailing...
"During the spacecraft’s orbital insertion burn, which occurred 31 minutes after liftoff, two of Starliner’s thrusters didn’t fire as expected. The first failed after only one second. Its backup immediately kicked on and was able to fire for another 25 seconds before it also failed. Redundancy failsafes activated a tertiary backup for the thruster group, and Starliner was able to complete the crucial burn without incident. "

@2ck Boeing had to redo this uncrewed test on their own budget, so those mistakes really hurt.
I'm glad they are finally are moving on with this. We need to have multiple launch options.
