Guys,
Don't you think the Air Force have anything better to do than listen to members of the public whinging about their aircraft (be it fast Jets or Multis) over civvy airfield airspace? I am sure they know what they are doing. I am also sure that the Sqn Ldr Ops, SATCO or Wingco Ops at which ever Station you contact has got enough on his/her plate.
They have to practise somewhere, and for goodness sake, we have few enough aircraft and Stations as it is now...give 'em a break! Be pleased that they are prepared to defend you! I live and work with FJ noise, trainers, multis in the air all the time and find it rather comforting...and... I fly from an RAF Airfield...where all types of aircraft be they light, heavy, slow or fast work around each other..we're all adults!
