Those engineers are long gone and not coming back.
As they say in the military and what the younger generation is being forced to learn - "embrace the suck".
My son who works for Boeing (not AeroSpace division) mentioned a rumor that sends a 4-man SpaceX ship to the station with only two pilots onboard. They will retrieve the two NASA guys and return to Earth. Then the StarLiner will be decoupled to return unmanned. If successful, great. If not no lives lost.
