/NOTE/ About the Starliner crew 'safely on the ISS'... there is one element that is an 'issue'.
The Starliner crew-pressure-suits are incompatible with the SpaceX Crew-Dragon. So, until the Starliner crew gets SpaceX Crew-Dragon compatible crew-pressure-suits... even though they have dedicated emergency-evacuation seats available on one of the Crew-Dragons
right now... they would have to undock/land in their ISS-NASA fabric cabin-flight-suits. I seriously doubt that they would [be-allowed-to] wear non-functioning pressure suits... NO hook-ups of any kind... NO comm, NO life-support, NO-cooling, electrical, etc... for a host of physiological factors. And they would just to 'take their chances' on the safe/routine return of the Crew Dragon. Crew-Dragon depressurization would be a death sentence.
Perhaps this is ultimately a ANOTHER major lesson-learned: All launch/re-entry crew-pressure-suits must have common/compatible interconnections with all crew-transport capsules/vehicles. Hmmmm that seems a bit intuitive, doesn't it? IF I recall correctly... Apollo 13 capsule and LM had incompatible air purifiers-filters that had to be emergency-adapted to keep the crew alive/breathing...
Perhaps NASA-Boeing-SpaceX could rapidly devise/test/validate interconnects for Starliner crew-pressure suits to the SpaceX Crew-Dragon??? Naaaaa
I suspect that they will 'play the odds'... and just launch the Starliner crew-return-mission Crew-Dragon spacecraft with SpaceX pressure suits strapped-into the vacant seats... plus cargo.
Hmmmm... If done correctly this spacecraft-interconnect could also be adapted to 'go the-other-way' too, fairly easily... Crew-Dragon pressure-suit to Starliner might also make sense.
