Dan Nguyen shot this photo and shared it in the Boing Boing Flickr pool today. Here's a related shot. He explains:
Hundreds of pilots from United/Continental showed up in full dress and made a show in support for their union during an ongoing labor dispute. They stood in an area on Broad Street, near Wall Street and the Stock Exchange. The organization is unrelated (formally) to #occupywallstreet; it just happened to coincide at the same time.
