Uniformed pilots, more than 500 at least, gathered in a pre-arranged area near the Stock Exchange for about 10 minutes. No long speech, mostly a photo-op, then they headed back out of the Broad/Wall Street area. The organization is unrelated (formally) to #occupywallstreet; it just happened to occur at the same time.
Clarification: There may have been picketing for most of the lunch hour till about 4ish. I saw pilots walking through the Financial District before noon. The photo op, which is what you see here, lasted not more than 15 minutes as the pilots were allowed to fill in the fenced off area near the Stock Exchange.
(There was a truck behind me with photographers, which is why the pilots here are looking up)
Getty Images had a photographer there who actually saw the protest, I caught only the tail end of it: photos.denverpost.com/mediacenter/2011/09/photos-airline-...
