I wasn't sure if this is their way of entertaining tourists or they were just hanging around there. It's obvious this wasn't Air Force One that was on the news a few weeks ago, they were the NYPD roaming around and waving the tourists on top of the Rockefeller Center. What are they doing? I don't know.
This happened when we visited New York City, a few days before the Air Force One incident that was in the news. The NYPD chopper circled the Rockefeller Center observation deck a few times, then flew off to buzz the Empire State Building.
