Back in about 1961 I was learning to do wingovers flying on a parade ground at an air force base. What I didn't realise was that every time I did a wingover I was taking a pace or two backwards. Next thing I knew there was the model skidding along these power lines with sparks flying everywhere from the exposed leadouts under the wing. A sudden thought went through my mind that I was holding a metal handle so I threw it away. Of course, if I was going to get zapped it would have been too late by then anyway . The model finally fell off the power lines and had a bit of a crash. The worst part was that I blacked out most of the base . Strangely though I never felt even a tickle from the handle and I've always put it down to the fact I was wearing heavy air force working boots.
