Helicarrier
The bird Phobos watched for was high above the bay, and Nick Fury was on it when things went fuck ass crazy down in Queens. At early word of the rioting, Fury held back his people and waited for the police and their SWAT team to handle it. When reports came that capes had joined in the chaos, Fury deployed teams of agents into the fray who would send back communication that the cops had joined in the rampage.
There was radio silence when even the agents succumbed to whatever the fuck was happening down there and became part of the commotion (those who didn't run and hide did, anyway). S.H.I.E.L.D. lost any link to reliable information and Fury ordered the helicarrier over the city in the hope of quarantining the area and shutting this down before the terror and chaos spread over the entire city.
The nearer they got to Queens the more uneasy the agents in the command center became and a few of them left their posts to pace the expansive space, apparently absorbed in their own thoughts. Fury didn't know what the hell this was, but he didn't like it. He demanded they stop, outside the boundaries where the media reported the worst pandemonium, waiting for renewed radio contact and calling for S.H.I.E.L.D. to set up a perimeter. Try and keep the crazy confined and hope it wouldn't spill out.
