We have several 757´s and they are quite a mystery in many ways. I used to think that airliners were quality built and precisely. But the air-conditioning noises (in the cockpit) are driving me mad (and deaf). Why doesn’t Boeing take pride in the working environment of the pilots?
Also, the noise differs between aircraft. While some 757s may be tolerable other are just screaming loud, so loud that they can’t be flown with both packs on. Is this difference because of sloppy craftsmanship?
Are there any jet cockpits noisier than the 757?
