Private citizen space travel is not a common event yet, but with all those billionaires working on it, it's inevitable.
Before I sign up for a trip, however, I want a cheap seat with a safe track record. Maybe I'll live that long.
In the meantime, I keep my phone on "airplane" mode most of the time. Seems that when someone tries to call I'm either driving, with people, or too far from the phone to answer it. So "airplane" seems like the right status to be in.
But I'm not a jet setter. So the "airplane" mode is a fiction. If it's going to be a fiction anyway, I want a space craft mode. Our local airport can get away with calling itself a space port, then by golly, I want that cell phone space craft mode.
