From what I see the thrusters are faulty.
Boeing said the cause is a Teflon seal bulging, they cannot identify why and when it is bulging but they say it will not happen on the way down.
Also, all the previous flights of Starliner had thruster malfunctions or shutdowns and they "fixed it" without knowing the root cause of the issue.
What !?
Until now I never considered that it would be made illegal to hang your clothes.
This is distopia material.
