Helicopters fly over my house all the time going to and from the Olympia airport and it doesn’t bother me in the least. I don’t go to bed much before 1 a.m. and I don’t hear them flying at that time.
I spent three tours in Vietnam, the first was with Special Forces and the last two tours I was a crew chief on UH-1 Hueys, OH58s, and OH6s. I have quite a few hours of combat flying.
People today should appreciate the training of the pilots and crew members. I am sure that previous complaints on the helicopters flying too low and making too much noise, if that person had to have a family member be evacuated by a medical helicopter and they were one minute late they would whine about that also and would wonder why they weren’t there sooner.
