Moving somewhat slowly is fine, but 40 years (going on 50) may be excessive. And as long as it adds hassle and expense to air travel, it means people will be more likely to drive and in turn to get in car accidents. (Of course, those lives aren't on the FAA scorecard, so they obviously don't matter. They probably don't even fly first class. </snark>) And it would be very handy in a variety of cases for "one air traffic control center to take over for another with the flip of a switch".
