When I was living in the DC metro area it wasn't speeding on a bike that was the most dangerous it was the traffic and the number of people who literally do not see you and pull out in front of you. That's what I was always on the guard for and being on guard kept me out more than a few life threatening accidents.Danged! That sounds a bit risky, indeed. Glad you survived so we can have the pleasure of your company here.Couldn't you have pulled the circuit breakers? The first thing we do when working on any electrical unit on an aircraft is disable the system by pulling the CB. (The second thing is to label the CB and the controls so the flight crew doesn't operate the system.)
No, I had to have the lights working to see which bulbs to replace. What is more I used to walk the roof in bare feet because they are a better grip than shoes. So I was well earthed and could have got a severe shock. I thought later that I should at least have used rubber gloves. But at the time I did not think of it.
The roof was metal and if it rained it instantly became very slippery, so I had to come down before I fell down if it rained.
I took more risks on motorcycles than on walking around on roofs. I used to do 120 Miles per hour on my 650cc Honda. The very first day I went out on it I thought I was doing about 50 mph but then a lorry pulled out a long way in front of me so I started braking, I glanced down at the speedo and found I was doing 90 mph not 50.
I was lucky to be able to stop in time, and I realized a 650 Honda with a streamlined fairing was a different kind of ride to my previous bikes. From then on I regularly did 120 mph on it.
