I read some of the NASA books recently and you’d think things are going without a hitch and yet hundreds of anomalies happen along the way that the casual observer simply didn’t see.
In contrast a flight with no engineering issues through heavy weather and turbulence would have many in the cabin stressed.
And shortly after I could see that, yes, they had good reason for these detailed precautions.
IIRC during the DEMO-1 launch, the two astronauts mentioned that their suit zippers were not fully fastened and there were minor suit pressure leaks.
Flight rules say they can't approach the ISS unless they have 2/4 propellant heaters working, and right now they only have 1/4.
EDIT: On the livestream they just said they fixed it.
