NASA unsure Boeing Starliner will ever be certified for human flight

Place your bets, because it looks increasingly unlikely Boeing's Starliner spacecraft will carry astronauts again, if a NASA inspector general's report is anything to go on. Published on Tuesday, the OIG report on NASA's management of its Commercial Crew Program (CCP) examines how SpaceX and Boeing have performed in providing crew transportation to the International Space Station. The report notes that SpaceX worked through its own technical challenges getting humans into space and to the ISS.
