I am NYC-based and my biggest fear isn't a fat Canadian Goose, it's a Bell helo or a Cessna/Piper/Cirrus. The tower/dep/arr controllers at LGA/JFK clear these aircraft through our airspace like they are non-existant. I've shot my arm out a few times in past couple years in the right seat yelling, "Traffic!" The news helicopters and GA traffic out of HPN and TEB have seemingly have free reign over the safety of our commercial aircraft. LAX had a couple well-known instances of mid-airs in the 80s. I'm afraid we might be on the same track in NYC.
