Thank you for your reply. I honestly don't understand the AT system, so will revoke any comment, if it's incorrect. However, in this case there were more than enough free rooms in all on-base messes. Indeed, the crew appeared to make very little effort in ascertaining the number of available rooms on-base. Furthermore, having served in Ali-al-salem, I could never understand why the AT crews would stay in Q8 city, whilst all the crews flying Op RESINATE sorties (24hrs a day) stayed in the pits, where I can asure you, there was more than enough on-base accom.
