I have been thinking about cross training to be a boomer, what all does this job entail? I thought I knew, until I was reading more on about.com and it seems to be alot more involved then I thought.

It is much more involved than just Air Refueling. Lots of additional cargo tasks/passenger tasks to be signed off on. My wife is about full mission qualed in this job and she has had to learn all sorts of things that one wouldn't expect a boom to have to do. It was more than she expected she admits, but she does like it 85% of the time she says. LOL
