A Brooklyn Life took a trapeze class and she lived to tell the tale on her blog. Check this out: And read more at the blog:

Normally, precocious seven year olds don’t calm my nerves, but the
three impatiently waiting for my morning trapeze class to begin did
have a soothing effect. After all, if children half my size and with

confidently thought to myself.

I was the first of our group to climb the ladder. I do not like
heights. I am not deathly afraid of heights, but I am afraid, and I do
not seek them out–I respect them. And so, I followed my rule of thumb
on the way up: Do not look down. Of course, one does have to look down
when standing with all 10 toes hanging off the platform, hands
outstretched on a metal bar, body tilted at a 65 degree angle over
empty space. An instructor grasps everyone’s belt as they  hold this
position and then commands "hep," which means "jump!"
