Almost a year ago we moved away from suburban DC. There I was used to seeing military planes and choppers because we were maybe 3 miles from Quantico Marine Base and within 30 miles of probably a dozen bases all around the area. Now we are out in the Blacksburg Va area. We are maybe 2 miles from the edge of the Radford Army Ammunition base. One nice benefit is a great fireworks display every 2-3 months. But also 1-2 times per week we have fighter planes flying here. I usually don't see them (lots of trees and low cloud cover) but can definitely hear them. One sighting was a low pass right over the house. I would guess maybe at a 1000ft. or less. W/ so many trees I could see twin tails but couldn't tell if they were vertical or splayed apart at the top. So F 15, 22 or 35. If he wasn't in afterburner, he sure was at full throttle. So I wonder why. I actually enjoy it. But I am curious why they are here. Is it just getting in hours at the stick and they can do stuff over a military facility that they can't do over the general public. It's not just a nav practice because they wouldn't need to be low for that. Ideas?
