Want to fly like Superman? Want it badly enough to spend $3500 to do it? A company called Zero Gravity Corporation will take you up in a plane that goes through parabolic flight maneuvers. And when a plane does that, you can drift around its cabin for thirty seconds or so like the astronauts do when they're not driving to Florida with diapers on.
The company website will tell you all about it, including how it works and how you can sign up. I've never had the particular dream of flying but if you have…well, you probably still don't want to spend that kind of money to do it. But you might enjoy a little window shopping.
