PJ2, FB...
I can say this, that after 911, there was a very serious effort in these regards.
With ADSB, there has been ADSB IN capability on many aircraft for quite some time now.
If the aircraft is on a coded procedure, where do the speed and altitude commands originate?
(thats enough at this point, I dont want the black SUV's showing up)
