Oy.
I'll just touch on the first idiotic claim in that letter.
NEWS FLASH: I am not an ATC, but I do know that the RADAR coverage and the screen which shows the transponders of the various aircraft CANNOT be overlaid. In other words, if the plane's transponder is off and the ATC is looking at the transponder tracking, the plane with the transponder off WILL NOT SHOW ON THE SCREEN. Got it? IT WON'T BE VISIBLE NO MATTER HOW HARD YOU LOOK.
Switching to RADAR coverage immediately removes ALL the identifying information of the flights in question and merely shows the tracks, making it virtually impossible to pick the one flight you need to be tracking out, especially if it's in a high-traffic area. And from what I recall of seeing the RADAR coverage an ATC would be able to see, pretty much the entire friggin' USA is a high-traffice area.
That answer your question Vinnie? This guy gets something COMPLETELY wrong straight out of the chute, and then goes on to repeat tired, debunked nonsense that was covered between 2004-2006 and presents it like it's new evidence of an INSIDEJOBZOMGWTFBBQ!!!11!11!!eleventy!!11. It isn't new, it isn't correct, it's just sad.
To the original poster, I say this: LEARN TO USE THE FORUM SEARCH FUNCTION BEFORE POSTING NONSENSE DEBUNKED OVER FOUR YEARS AGO. Please.
