Over the next few months, I will assistant stage managing for a high school production of Mary Poppins. One of my specific responsibilities will be to oversee the flying in the show, both of the scenery and the people. We have obviously contracted with one of the many flying companies, which will install, oversee and train me on their system. However, I was wondering if anybody could lay out some of the basic differences in flying a person compared to scenery. I have extensive experience with a counterweight scenic fly system, but have not worked with personal flys before. While I will obviously be trained on all of this, I would be very grateful if somebody could give me an overview of the mechanics of flying a person so I am better informed before going into training.
