Yes, definitely makes me feel safer......
....especially seeing these guys usually either watch DVDs on their lap tops, play video games, or forget their guns in the lavs....
Seriously, I think 7D on the MD and 7C/D on the 737 are the prime seat for these guys, if they even need to be on the plane in the first place.
I once flew RT DFW-CDG-ORD in J and saw the same pair of guys on the same flights......
