I find this "noise" problem quite funny (ha, ha). Back in the days when we had real noise problems, it was caused be the older non by-pass engines on DC9, B727, DC8 BAC 111, etc. In todays world with Hi By-Pass engines there is no longer a "noise" thing. These modern engines are way much quieter than back in the 80s. Any country that is still fussing about noise should have their heads examined. It's just another tax grab. Totally unnecessary. If they keep bugging you, take them to court !!
