This whole submarine thing is a preview of exactly how "space tourism" is going to go

@tomw It depends. Virgin Galactic has killed two staff when one of its vehicles crashed, and the safety of its (not-quite-)spaceplane has certainly been questioned.

On the other hand, SpaceX has been doing space tourism with the same launcher and capsule that NASA has been flying its own astronauts, so it meets NASA's safety qualifications.
