Space exploration promised us alien life, lucrative planetary mining, and fabulous lunar colonies. News flash, ladies and gents: Space is nearly empty. It's a sterile vacuum, filled mostly with the junk we put up there.

Everyone loves to fly, and flying underwater is even better than flying in air because there are things around you.
There's something just magical about flight. Period.
