A few years ago I was reading a novel where the main character became a wing walker.
By coincidence, at the same time, Utterly Butterly (a brand of spread in the UK) were giving these cooking timers away.
They are the sponsors of the Utterly Butterly Barnstormers, a wingwalking team. http://www.aerosuperbatics.com
Don't think I could ever be a wingwalker!
