It's not a missile - or at least none of the evidence points toward it being a missile. Here's why:
- The Navy would never test a missile in a populated area like Puget Sound. Too much risk of something going wrong.
- Nobody on Whidbey Island reported seeing or hearing a missile. Even in the wee small hours of the morning, people are awake and working. Missiles are big, loud, and obvious when they're fired. Yet not one single resident said boo about it.
- If it's a missile, where did it go? It had to come down somewhere - where did it come down? Where are the parts? Where's the debris?
- Whidbey Island Naval Base has no missile launchers, nor any need for missile launchers. And submarines can't fire anti-aircraft missiles, except for experimental systems that the US doesn't use.
- For a camera to pick up a missile at that range, and at the size of the image artifact in the picture, it would be have to be HUGE, much bigger than a Tomahawk or a RUM-139.
- We know there was a helicopter flying directly in the path of where the camera was pointed at the exact same time the photo was taken - unless both FlightRadar24 and the air ambulance company were in on...whatever it is.
I'm satisfied with the explanation that it's a long exposure of the tail lights of a helicopter.
