Initially, it being a new frontier, it would be Navy, hands down. Has to be. But I am certain there are roles that the Air Force could offer that would be beneficial. They got some pretty smart guys too.
But after it get's dialed-in and common place, such as air travel is today, I am sure the Air Force can more than adequately assume the position. And are even better suited for it. They are the best.
The Navy avaitors just takes "best" to a higher level. It would be a shame to waste such talent on such mundane things that have become run-of-the-mill repetition. There is ALWAYS another frontier beyond.
