Behind the scenes ~ high up in the sky

It is one of the jobs you don't really think about. The person operating the tower crane at a job-site. They are way up there in the sky. There's nothing like a large group of 3 to 6-year-old children peppering you with questions to remind you that this is interesting and you want to know more. Of course then, I wanted to know more myself. One of the foremen on the job, the first month I was there said rather casually when looking up at the crane, "I couldn't do that job." Yes, but why not is what I wondered. The video here is an attempt to answer just a handful of the questions as it relates to this job. {warning, if you have acrophobia -- you might want to skip watching the video}
