Was there any warning that this was going to happen? Was it NOTAMed?
It seems that this sort of thing is becoming quite common. I got caught out with the flypast for the Queen's Birthday. Forecast great at LHR. No hint of a flypast or reasons for a delay, so we took flight plan fuel. Long delays out of our departure field, headwinds en-route and then 30 minutes going around the hold on a CAVOK day. We were very tight.
I did write it up - but chances of a reply are nil.
