I grew up mostly around here, and I used to be stationed at NAS Whidbey. I can attest to the noise of the jets flying around the island. It happens. Now I live east of the island, over on the mainland, but I'm still indirectly under the flight path, even though I'm a lot further away. I hear jets from time to time, but nowhere near as badly as I did when I lived on the island. It's a non-issue for me. People just have to get over it. The jets aren't going away, and they're training so they can save our collective bacon if need be.
I have the most issue with people who move to places like Whidbey because it's so scenic and affordable, then bellyache when it's different than they expected it to be.
Example: When I lived in the San Juans on Orcas Island (not very far from Whidbey Island) I got a major kick laughing at all the out-of-staters who came from elsewhere, bought property on a whim, and clear-cut the timber to help pay to build a McMansion surrounded by a huge fence. They paved everything, and put up a super-manicured, overly-landscaped yard. Then the first Winter, after they got windburn from the Northeasters blowing over the island past where all the trees used to be, and when the pavement grew all sorts of moss and slimy muck that made it slippery as ice, and they screamed bloody murder in the Spring when the deer ate their rosebushes and bit the heads off their daffodils and tulips, only to spit them out because they're bitter...
These people would stand and tell everyone who'd listen about their terrible dilemma, complaining how they'd spent all this money, and that the islands were losing their appeal because of all the outsiders moving in. And then they'd ask why there wasn't a McDonald's on the island.
Life happens. Deal with it.
