They're usually :doing Mach over the states. Since this is a normal routine - then the :complaints must be small. When I was stationed in Fortuna ND (Near Crosby :north of Williston) we heard a boom just about every monday. Every monday :except when the turkey farmers didn't post a NOTAM - prohibiting supersonic :for the duration of egg laying or whatever turkeys do... The SR71 does Mach overland? I didn't know that? How come Concorde can't? No flames please, this isn't a major gripe, I'm just a patriotic Brit who thinks Concorde is just as beautiful as the SR71 (or F14 for that metter). Tarqs
