Wow, hit a sore spot did I? Some people put that they edited out their comment so people wouldn't get confused. Give it a try, when everyone seems supprised, you can say that you got the idea from a "Sir Master Flight Instructor", that way people will know where you got such a good idea.
Anyways, back on topic (sort of) how does Walmart block their tail numbers from being tracked from FlightAware?
