I'll be in New York City this weekend shooting some conventional footage on Canal Street (lower Manhattan) for a 'not for pay' project I'm working on. I AM DYING to bring along the P3P to get some basic aerial sweeps of the street for transitions and such. I see there's no NFZ's for the area...most of Manhattan for that matter...but I'm still reluctant unless I can get some assurances I'd like to get some guidance from anyone who's shot in NYC...did you have to get clearance? if so, from who? Technically speaking, even though I wouldn't be flying very high, or out of LOS, should I be concerned being that close in to city based buildings? Whaddya think?
