Zero-gravity flights are all the rage . Cage diving — swimming with sharks from behind a cage– is everywhere sharks want to be. And the venerable Abercrombie and Kent runs an offshoot called Extreme Adventure that offers trips like tracking polar bears and looping over South Africa in a fighter jet.

That stuff is for sissies.

At least it is if you compare it to a new offering by British travel company, Black Tomato: Everest Skydive, slated for September. Just what it sounds like: You can jump out of a plane at 29,500 feet, the height of the mountain, right next to the mountain (for 15,900 British pounds for a solo dive). “The fact that nobody has ever attempted this skydive before means that you will literally be making history,” the Web site gushes. Let’s just hope you won’t be making news. Splat.

I understand kayaking on waters until your arms ache or hiking into the woods until your legs feel like jelly. That’s about challenging your body — and reaching a pristine place. This stuff, I just don’t get.

If you want to take this trip, or at least understand the drive, please enlighten. Also, what other adventures that I haven’t yet heard about await intrepid travelers?
