[QUOTE="cody6766, post: 2075083, member: 26511"] Yup, air traffic doesn't just leave Airport A and head direct to Airport B. There are highways in the sky with intersections and turns that we use to get around. There are waypoints that we use to enter and exit those air highways and they're common crossing points. Ever wonder why the contrails all seem to turn and cross in a similar location, like over Will Rogers, Amarillo, or other airports? It's because they have radio navaids that crank out a signal for airplanes to use. Google VOR, VORTAC and TACAN for more info on them. When driving down I40, across from Tinker, look north when you're right across from the runway. You'll see a goofy white topped building in a clear area. That's Tinker's TACAN. This is a 'roadmap' for the sky.
