At EGTC various restrictions were put in place, none of which were necessary as we saw maybe 2 business jets daily. In the meantime, we've just been told that having banned all fire crew leave through August, nothing but light aircraft ops will be possible with September as they all go on holiday.
At EGTB I largely avoided and ignored it until late in the process when I particularly wanted to do a trip through there (straight out of the zone). I tried for over 2 hours to get a flight plan accepted, but it continuously told me I couldn't - well fly from EGTB to the lat-long for Stokenchurch mast basically. Utter cobblers, but I gave up in the end and didn't fly.
On the whole, it was a royal buggers muddle and most people just didn't both flying anywhere near London. The economic damage to various airfields and operators in the SE will be substantial but very hard to quantify.
