"Mike, if you really want to pound your head against the wall, watch the Mythbusters episode on tracer ammo. They explain that it is a phosphorous coating on the outside of the projectile that lights up because of the supersonic rush of air over it."
Hum...
Adam and Jamie. Former military? Nope.
Mythbusters, show about military history? Nope.
Mythbusters, has military advisors on staff? As far as I can tell, nope.
Mythbusters, on the History Channel? Nope.
Substitute R. Lee Ermy and History Channel for those questions, and they all become yes.
That's why that fail is so much more annoying, and egregious, than Mythbuster's fail.
