Am I too cynical for immediately thinking: a) this is a byproduct of SpaceX's successes lighting a fire under establishment aerospace corporations and b) we're more likely to see 1 launch in 20 days when fully implemented?
People on HN, maybe not you, love Musk. He accomplishes a lot in tech but must he get credit for everything, even the things others do? Boeing has a long track record of major technological innovation and development. They also build the X-37, which seems much more similar to the XS=1 than SpaceX's systems.
