North of Mountain Home Airforce Base.

I live about 1½ NW of Mountain Home Airforce base in the Caldwell/Nampa Idaho area.
I was in my backyard and happened to look up. I saw this military jet, flat out hauling the frick'n mail. I know there's no reference or way of measuring just how fast hes going. So you'll have to take my word for it. As a former 0311 US Marine I've seen jets flying very low and very high, at all different speeds. So when I see a jet moving across the sky I can tell the difference between commercial and military speeds.
