.... RADAR. It has had it's day, a very significant day, but it is no longer the means of surveillance of choice, it is primitive and antiquated when compared with other technologies and therefore... insignificant in the security world.
Quokka, I addressed your other pionts in my previous post.
re the quote - One thing our current ATC system has, it is here, now, and it works when it is
properly maintained and staffed. With the
system of independant NDBs and VOR/ILSs and dedicated ATCers, there is not really any key component that, if removed, could bring down the entire system. ADS-B on the other hand....
IMHO, a
robust ATC system has a lot of relavance in todays 'security' world.
