Capn Bloggs - what's your point?
The canadian is obviously accusing the complainants of moving in after the operation started, and therefore have no right to complain (with which I agree). I am merely asking him what evidence he has that that is actually the case ie that the op was there before the noise complainers moved in.
Or were the hillbillies there first?
Bit unrealistic to expect a Canadian to know the exact circumstances of one airfield in Australia.
He posted it, so he must be an expert on the situation...
