It isn't, usually.
But, when one sees one's mission crew swanning around a foreign squadron bar, the flight deck crew have gone back to their accommodation for a ****, shower and shave and returned to said bar before heading into town, it makes one smile.
Particularly when mission crew come off somewhat for the worse after a scuffle with our host nation's finest.
Thats not saying a lot for E3 flight deck......average age 50......so out for dinner at 1600 (missing happy hour)......pipe and slippers in room at 1800
