As much as I admire Captain Sullenberger, I see no reason why his opinion should outweigh those of the pilots and air traffic controllers working with the current system on a daily basis. 

If the current system is to be retained then immediate reforms to address a dysfunctional system need to occur. Just because there haven't been any fatal crashes since 2009 doesn't mean we should continental to waste money and ignore the multitude of near misses and do nothing until catastrophe happens.
