I'm half-way done now. My specializations are human factors and airline operations. I got started one day in May 2000 because I'd been out of school for a year and missed it, I like learning, interacting with others and sharing knowledge. Basically, 10%-20% of each class is doing exactly what your're doing now on this board. The rest is a mid-term, paper/project and final.
The degree's worth? Don't really know execpt maybe what you place on it. After my original impulsivity, I reasoned that if I got out of piloting, I'd have an edge in the industry and other valuable knowledge than just flying stuff. PM me if you've got specific questions.
