Why? Mustn't be that difficult to pull off such NOE flying for those skilled pilots and not that impressive to look at for the public...unless they actually want to actually alarm/unease the public. But IF the .001% chance of an accident does happen, it'll be a big mess economically, politically and a huge embarrassment for the military.

Is this done because of the UN General Assembly I saw & heard going on? It's the only reason that this makes sense.

Seems like a completely unnecessary risk. I thought it was going to be one loose cannon pilot until I saw how many flew under. What would happen in a bird strike situation?

Anyone who's seen a FOD check on an aircraft carrier realises how retarded one helicopter doing this is, let alone a squadron. Chunks of shit fall off those bridges every day just due to age. Not to mention idiot pedestrians actually TRYING to hit one with a beer bottle. One big enough piece of debris into the jet intake and you're in the river.
