Honestly they'll be talking about NextGen when even the youngest person on APC retires. What's wrong with radar anyway? WWII-era equipment? So are florecent bulbs and WD-40 but you don't see them going out of fashion any time soon.
It's the biggest red herring in the history of the world. What a better way to blame overcrowding of NYC's airspace, lack of qualified controllers, and not enough runways than some pie-in-the-sky technology that is way out of our price-range? I can't wait for all this new stuff to be implemented and STILL be stuck at JFK for hours in the conga line.
