Not only would I not pay twenty five dollars to do this, but I would require receiving vast sums of money to do so. But there may be a market for it.

[Update late, after getting back to Florida]

Yes, I did mean acrophobic, though I suppose the Grand Canyon could be heck on agoraphobes, too.

The CN tower in Toronto has a section of lexan floor with about a 1000 foot drop.

My daughter shamed by tap dancing all over it.

I just couldn't stand on it.

I justified myself by explaining how UV bombardment could cause unseen weaknesses.

But that doesn't explain how I can walk through the lexan tunnel in the SeaWorld shark tank with no qualms whatsoever.

Oh, that one's easy. The water protects it from UV... ;-)

For the view, I think I could manage it, though I couldn't say for sure until I experienced it. I could get a touch of vertigo. I don't have serious agorophobia, but I do get uncomfortable standing near the edge of sheer cliff. Still, I've done plenty of steep hill climbing and roof work. The key for me is the feeling that I'm secure.

As an airline brat I had plenty of early chances to look waaaay down, loved it, and took for granted I had no problem with heights. It wasn't until a visit to the Eiffel Tower that it came home to me what a psychological difference there is between a big drop "out there" -- even the edge of a cliff -- and a big drop that's very visibly under your feet.

A nit -- irrational fear of heights is called "acrophobia". "Agarophobia" is a fear of open places -- agora is Greek for "square" (as in "Red Square" or "Times Square", not "geometric figure! :)

But that doesn't explain how I can walk through the lexan tunnel in the SeaWorld shark tank with no qualms whatsoever.

Because you know how to swim??

Even severe acrophobics are not usually terrified by looking down an expanse of water (from a low height, of course). OTOH, people who can not swim can be scared that way -- but in their case it is a rational fear.

Hooooooo! You mean acrophobia but, yeah! Wow! I think I would do it, that would be a heckuv an experience.

I have a great fear of heights, but I tend to trust good engineering: glass floors, aircraft, suspension bridges (e.g. capilano).

Me in Auckland's Sky Tower this week: http://www.canllaith.org/northland_trip/slideshow_4.html?10

Very amusing. A group of tiny Japanese women were standing beside one of the glass panels, reluctant to put so much as a toe on it. So I walked into the middle, jumped up and down a couple of times (I'm 260 lb), smiled at them, and walked off.

why is a message containing "a f r a i d" rejected as "questionable content"?

I'm having some problems with the math. Supposedly this skywalk holds 120 people but can support 72 million pounds? Are these people going to drive their own personal M1A1 tanks (the claimed load is 300 tons per person which is about four such tanks) onto the skywalk? Seems a bit overengineered. ;-)

Elevators are routinely overengineered by a factor of ten. Considering the potential outcome of this skywalk collapsing, I think a lot more "overengineering" is reasonable.

If you lay down on your side, then it might produce agoraphobia!

If I knew it could support an M1A1 Abrams, I'd feel more comfortable visiting it. My problem really isn't the concept of looking down into a lexan covered hole. My problem is looking over the edge of a guardrail with high winds. Haven't been to the Eiffel Tower, but I would think the wind thing would bother me there as well.
