There appears to be some disecrepancy between reports concerning this 'event'. If a 'flypast' turned into an anauthorised and unapproved display - note that I say 'IF' - then there are certainly legitimate grounds for concern.
However, there are more appropriate ways of expressing that concern than in a public forum.
Remember Ramstein? The UK has some pretty strict air display rules - as a result there hasn't been a member of the public killed since the crash of John Derry's DH110 at Farnborough in the early 1950s. Impromptu unauthorised displays by the unapproved will inevitably attract severe repercussions - and quite rightly so. There have been some pretty serious allegations made on this thread - if you have a genuine complaint, perhaps using the correct reporting chain would be a better way to ensure that it is investigated?
