"petulant idiot" ....... best you copy the Americans (and, in my personal experience, the Indians, the Pakistanis, the French etc) into your complaint.
ICAO - smoke screen - International Civil Aviation Organisation. Last time I looked, a TU-95 with a Red Star on the side wasn't a civil aircraft. Nor was the F15 that chose to take a close look at me the other day and, shock horror, failed to comply with the ICAO Standards and Recommended Practises. A quick look at the UK legal framework will tell you that the UK military doesn't have to comply with ICAO SARPS.
Some of you guys need to wake up and have a quick look at international law and not a gentlemen's agreement signed at Chicago a few decades back. Sure, its not very clever driving through Class A/B/C without coordination but that is one of the very reasons that the UK and NATO maintain a surveillance infrastructure such that they can identify Pesky Ivan and safely escort him through the skies.
Purleeeease don't join the Daily Mail bandwagon and tell professional aviators (especially those who have spent their lifetime dealing with such activities) that this is outrageous, unsafe, frivolous etc.
