Fear of heights and flying have held me back from doing this, but if I knew I would have guaranteed safety, no risk of the balloon suddenly deflating, or getting caught in a gale, or plummeting to earth, I might have a go.

I’d have to be on a tethered line, and maybe not go any higher than ten or twenty feet!

Why am I scared? I suffer from vertigo if my feet leave the ground, so even jumping can make me dizzy (I exaggerate), but I think I know where it stems from.

When I was young I was happy to climb up the outside of the swings or the big slide in the park or the ropes in the school hall. I’d climb to the top and hang upside down. So when I was a teenager and went on a school trip I was fine. But I borrowed some binoculars from the school teacher and climbed up a steep hill. I’d wanted to see the view. BUT, when I tried to climb down it wasn’t as simple. The surface was scree, loose small stones, I could feel the ground sliding away beneath me and I couldn’t use both hands because I was holding onto the binoculars for grim death! I finally got down in a flurry of dust and rough rocks, but I think it shook my confidence, I know from then on I was much more cautious and nervous about heights.
