In tradional air-traffic flow, one gradually descends and slows down as you approach an airfield. The problem is, the slow guys up-front start to bunch-up the guys in back, unless you have lots of miles of separation. (Imagine recovering 500 airplanes, like WWII).

So, if everyone maintains their normal cruise speed until the "break," spacing can be reduced. The break is about 2-3 gs in a T-38 or any other fighter-type aircraft; it could be more, but that is sufficient to slow to gear-speed in 180 degrees of turn. You can vary the g in the break to accomodate tower instructions for spacing.

While the history does go back to at least WWII, in Vietnam (and later), once shoulder-fired SAMs were invented, the break meant you were always turning the tail of your airplane away from any shooter, or, he only had a few seconds to point at the back of the airplane. This was significant as early man-portable SAMs could only shoot at rear-aspect.

Besides that, it looks cool and is damn fun!!
