Of all the loony "jump, dive, and scream" things I've seen, the catapults are the ones I find most appealing. None of that "watch the first step" panic of bungee jumping or sky diving. Then I saw this.

Yeah, even I have my limits. One rule of mine is definitely, "thou shalt not require a parachute to ensure thy safe return." Nice to have as a backup, but not required. Bok bok!
