Boeing’s Starliner capsule returns to hangar for valve troubleshooting

Ground teams at Cape Canaveral wheeled Boeing’s Starliner crew capsule and a United Launch Alliance Atlas 5 rocket back inside their assembly hangar Thursday for further troubleshooting of misbehaving valves inside the Starliner propulsion system. Without a quick fix, technicians will have to remove the spacecraft from the Atlas 5 rocket for more extensive work, potentially delaying the Starliner test flight by months.
