Obviously it will take some time for the full accident analysis but there have been quite a few near misses lately due to air traffic controller errors. Flight volume has been growing, airspace near airports is more congested, and controllers are overworked. Eventually all of the "Swiss cheese" holes line up. We're going to need to hire more controllers.
Also, it appears that one of the aircraft was a military (not police) H-60 Blackhawk helicopter.
