Boeing is now targeting June 1 for the first crewed launch of its Starliner capsule, though that date is far from set in stone.

The flight date for the mission, called Crew Flight Test (CFT), has been in considerable flux recently. It had been scheduled to lift off on May 6 atop a United Launch Alliance (ULA) Atlas V rocket from Cape Canaveral Space Force Station in Florida, but that try was called off about two hours before launch due to a misbehaving valve in the rocket's upper stage.
