My Granby was inglorious but not boring. HQ RAFG remained very interested [nosey, even] although a large chunk of our assets were deployed. Air Staff briefings were daily, and attendance escalated such that Sir Sandy decreed only Wg Cdrs and above "place smells like a zoo".
Our little Met cell had some mysterious extra comms equipment moved in, and three of us were to man it if push came to shove. There had to be a password to get into it, and we chose "umbrella" but the received wisdom was to have a miss-spelled version.
Thus DCMetO or Met 1 cracked his head under his desk as I wandered in and asked politely if he was sheltering from a scud. "I've forgotten the password, and its written under my desk!"
There are lots of ways of miss-spelling umbrella.
We never did use the gismo in anger..
