The AC of the B-52G in which I once had a trip was a dictatorial so-and-so, a young thruster intent on making a name for himself and securing a position at the Pentagon. His CRM even at briefing was radically different to the rather more genial manner in which Vulcan crews operated.
However, as we approached the entry control point in the bus, he snapped out "CREW! Rings off, badges on!", which was a reminder to wear security tags and remove any rings. It was probably about the only sensible order he issued during the entire trip!
