Fuck me no. I wouldn't sit there (OP). I was never that great with heights (tho I don't mind planes), until I was in my 30's and I started having Vertigo nightmares. I blamed it on the Hitchcock film (big Hitchcock fan), but this nightmare was terrifying, and some months later I had another one... and then a year later another etc, and it turned me into someone who now suffers from Vertigo. Ladders 10 foot up I start to get itchy palms etc. Am just no good with it at all anymore, and it was the nightmares that started it. Haven't had one for a long while, but I'm no good with heights now. Pictures like that in the OP does things with my head.
I got tickets to watch the Weightlifting at the London Olympics and stayed with friends in Deptford the night before. I was meeting a friend there the next day, and I was determined to travel by cable car alone across the river. I was pretty nervous, but excited - had never been on a cable car. What I was determined to do was to try and get the rational side of my brain to win over the irrational side. I wouldn't have done this if I was with anyone else, but on my own, I was more comfortable. Part of me was shitting itself, the other part was dead excited. I used to work in One Canada Square (for L!veTV no less - long story, don't ask), and used to eat near a window on floor god knows what so that was partly why too.
I wanted to have a car to myself. I didn't want to break down with anyone else there or have a panic attack, which I could have done. And an empty one came along. I got in. It started with a jolt. Shit me. I tapped my wife's number into my phone. By the time I finished tapping numbers I looked up and I was about 100 foot in the air over the river and shared my panic on the phone. I started to hyperventilate on the phone, and am not sure if it was due to fear or excitement or both. I put the phone down and rode the rest out. Fuck me. Thank fuck I was on my own. I was just shouting 'I'M GOING TO FUCKING DIE HERE!!!'. Was great.
