• Answer:

  I can't imagine why it'd be necessary to add that function to something that already serves it's purpose, other than for the 'cool' factor. I suppose if you have enough money it's possible, but I could never see it going mainstream. And even then, people seem to have a hard enough time as it is staying on the ground and following directions, so imagine the average person being an every day pilot. Boat's are meant to stay in the water, and if they were built to hover above water they'd probably waste a lot more resources just to do so, meaning it'd probably be pretty expensive just to use one. I guess planes could be built to go into space, but they're used to go from one destination to another, so adding that function just seems a little pointless. If you really want to go into space just pay to go on a space shuttle.
