Jon I think that this element is the key to the issue. Once you get away from having healthy debate with those willing to have it about flight safety there is inevitably going to be some form of enforcement of rules and here the situation in this accident the trail goes cold.
Early on the question was asked of someone who was reflecting an exchange he had as an AOC holder with the CAA. The silence is deafening.
It would seem quite logical that if individual pilots and flying clubs as a whole have identified things that go on that have raised concern - which include things they have identified online - it is reasonable to assume that authority would also have access to that information. As has been stated on the basis authority has not been taking pilots to task - I can only find the Manchester PA28 pilots who has been taken to court - don't you conclude that authority don't see this as an issue? Because the alternative is that someone has been screaming very loudly at Gatwick to do something for years and nothing has been done.
