Fortunately I haven't had to deal with noise issues, haven't been in the plane/airport combination to have this consideration.... But it reminds of guys I knew looking for jets for their boss, passing on 5 million dollar GIIs for 20 million dollar GIVs mainly because of noise abatement issues and some nod to range, even though they never took the plane anywhere with more then a half tank on board. I found it funny that some weak pilot could get some very smart guy, who's DNA is wired for making money, to part with $15 mil. more then he had to, because no one asked the question: 'So why don't we go to the airport three minutes away that doesn't have noise abatement?' Or - 'Why don't we drop a half mil. on a hush kit? or 'Why do you have to do an F16 carrier departure?
