 Two American astronauts on board the International Space Station who got there on Boeing's Starliner vessel are still stuck. Butch Wilmore says that glitches with the thruster and helium leak forced them to put the ship in manual mode to dock with the ISS. We are actually doing thruster testing as we speak at White Sands, New Mexico, going through that process, trying to replicate what we saw on that flight day two when we were rendezvousing, and we're going to learn from that.
