I bet the RT instructors have a lot of fun and see some really funny stuff. I remember this one student in my class, an SP who cross-trained to flight crew, broke down crying and wigged out when they made us strip naked in the cells.
I actually was interested in being a Survival Instructor, but they weren't recruiting when I was in basic. Fortunately TACP was recruiting, or I'd have been stuck in my original job: electronics tech.
I think Survival Instructor would've been a great job; I know I had a blast going through the school.
So your wife beats the crap out of trainees by day, then comes home and does scrapbooking at night?? LOL.
