Yikes! Not for the faint-hearted...

I get dizzy standing on a chair, how these guys do it I will never know. However, I have no problem flying a glider with nothing between my bum and oblivion than a thin sheet of glass fiber, don't understand the difference. It can't just be a height thing, must be to do with the fear of falling.

I timed myself for this one and lasted all of 6 seconds!

Well, I didn't even make the first level of the Eifel Tower so no surprise there then

Catherine Destivelle freeclimbing.

And again on the Old Man of Hoy whilst three months pregnant.

She must have a physical and emotional strength most men would give their eye teeth for.

Pompa, I find that it's not height that spooks me, it's insecure heights. As long as I'm strapped in or there's something to hang on to that's fine, but I can't hack it if I'm too exposed ,and dependent on my strength or balance. If I stand on something like a foot bridge over a motorway cutting, I can make my head spin by imagining that there's no railing, and then switch that feeling back off by acknowledging the railing again.

Strange how just watching something height-related on TV can bring on leg-trembling and feelings of fear, which suggests that for most of us the fear of falling is hard-wired into our brains.

Some of it is visual - the parallax effect of seeing things at different distances appearing to move in relation to each other as you move your head ever so slightly.

Catherine Destivelle moves like a dancer - I can't be as graceful on the level!

Just watching Destivelle is enough to make my palms sweat, but I can manage something like Striding Edge easily enough.

Is she human ??? Amazing, I was transfixed.

Hate heights/fear of falling so much that my palms are sweating just reading this thread! DH and DD both are glider pilots and I cannot be persuaded that it is fun.....no engine?! Yikes indeed!
