I hear you all and share your concerns.
In the forums on another space news site there have been a lot more updates and yeah, it doesn't give one a lot of confidence - not that we were overly confident with the mountains having to be moved just getting it launched and docked with the ISS. Especially since this mission is the 3rd flight of Starliner and is supposed to be the FINAL check-out before they start actual commercial missions next spring with a full crew, alternating with SpaceX every 6 months.
I don't know if they've gotten them sorted out but there have been chronic communications issues between Starliner and the ISS as well as between Starliner and the ground stations prior to and since docking. Systems have been going offline with Butch manually bringing them back online and trying to troubleshoot. Plus the whole issue with the cooling system going through all the water and having to resupply from the ISS, requiring an update to the next cargo mission.
Again, why are we seeing this on the 3rd and final "check-out" flight?
I did see that Nelson suggested using camera on the Canada arm to do visual inspections of the capsule to see if there are any external observable issues with the thrusters. Boeing has said both they thought the thurster issues were tolerences set too low in the software (again, why all this again on the 3rd flight??) or potential hardware/QC issues from the supplier (Aerojet Rockdyne). I haven't been following as closely the last day or so to see if that's still a plan. The big problem of course is the thrusters are all in the service module which will be jettisoned before reentry. So they will never be able to inspect it post flight to understand what's really going on.
It will be interesting to follow the post-flight review over the coming months. More details of the issues will be revealed / leaked no doubt!
