A polite reminder...
...that military airfield ATZs are H24 even if the airfield is apparently 'closed' and you can't get a reply on the radio.
While club duty pilot recently at 'ours' there were a couple of infringements - in one case the pilot called on the radio without receiving reply so then flew through the ATZ. Probably she thought it was OK, as at a civilian airfield if the airfield is closed the ATZ disappears. Not so at a military one, I'm afraid.
Not a big deal but worth remembering - we had circuit traffic at the time...
Thanks,
Tim
