 NASA officials insisting that the Boeing Starliner crew are not stranded at the International Space Station, but there's no date set for their return to Earth amid complications. NASA's Steve Stich. Our plan is to continue to return them on Starliner and return them home when at the right time. We'll have a little bit more work to do to get there for the final return, but they're safe on Space Station. Their spacecraft is working well, and they're enjoying their time on the Space Station. NASA blaming mechanical issues.
