I may be way off...but the only thing that came to my mind when I was watching it was that it showed some equipment in the background...some computer screens..etc...I know on a sub they don't like that. Let me see what I can find out.
I happen to work with the equipment that it showed, and the guys were doing some pretty weird things with equpment that is quite sensitive to motion (won't go beyond that - loose lips). I got a kick out of it, but I could see some people getting upset about setting a bad example for treatment of the equipment.
