During a recent press conference, it was discussed that the next flight of the Boeing Starliner spacecraft may not require another test flight before being operational with a crew on board. The focus is on ensuring that the next flight will be fully certified and ready for a crew swap.
While the details of the next flight are still being determined, the goal remains to have regular crew rotation flights to the International Space Station. This involves alternating flights between Boeing's Starliner and SpaceX's Dragon spacecraft.
