I live in the Appalachian Mountains of western Virginia. Our Air Force and Navy like to practice their defensive maneuvers in our area. They fly a variety of planes among our mountains and valleys executing dramatic ascents, descents, and sharp turns. This has been going on for decades.
About the year 2000, I wrote a letter to then Virginia Senator John Warner about a huge C-130 cargo plane that had disappeared behind the 1,500 foot hill in front of my home (which is at about 1,400 feet ASL). The valley floor beneath the plane is 1,200 feet ASL; the rear stabilizer on the plane is about 70 feet high.
Three members of our armed forces responded to my query to Senator Warner. All three assured me that it wasn't their airplane.
I concluded that it had been the Russians.
Now when I hear the jets, I look up and wonder if Donald Trump has started World War Three.
