How likely is it that the health effects of jet noise are exaggerated in Coupeville, Washington?
What a truck load of crap! What nonsense,,, so they shopped around and found a doctor or two that would say what they paid them to say. Easy to do in alt-left Washington State. 
I have lived and worked around jet noise nearly my whole life and no health problems because of it. 21 years as a Naval Aircrewman, around a lot of jet noise, and I am just fine.
Maybe the Coupeville snowflakes and COER Navy Haters can't handle it because they are infected with liberalism, which has caused them to be overly sensitive to loud, scary noises. If the sound of freedom bothers you, move away from it.
