I think some people just resent the fact that we have a military.
Agreed. Received a whine from some vineyard in Mudgee in the late 90's. They were having a music and wine festival of some description and complained most bitterly that the whole thing had been ruined by a Caribou overflying the place.
It turned the graceful lady of the skies had overflown Mudgee enroute to Amberley at 9,000ft (about 7000ft AGL). Now I can attest that a pair of P&W R2000s at cruise power aren't all that quiet but puleeeze! I enjoyed drafting the response....never heard another thing.
