Can you point us to a desolate range, several hundred miles in any given direction, so that fighter planes traveling in excess of Mach's number will have room enough to fly for more than a couple minutes before being forced to effectively double back?
Are you equally concerned about the commercial airlines that are flying solely between the most densely populated areas in the world?
Not to mention their primary mission is air intercept in this area, granted there are other ways to train for that, but nothing like the real thing.
Who is this wet blanket sissy?
