If you see a huge, white blimp in the sky, don't be alarmed—it's just Big Brother. Or the Navy. Notify NYC said, "Weather permitting, the U.S. Navy and the FAA will conduct capabilities flights using a U.S. Navy MZ-3A Airship (a blimp) in and around NYC tomorrow, 11/09/11, from 9:00 AM-4:30 PM. The flights will be based out of Floyd Bennett Field, Brooklyn, and will operate at altitudes of 1,000 feet and below."
