If you spotted people flying over various parts of New York City and New Jersey this past weekend, there is no need for alarm. It is all part of Thinkmodo's viral marketing campaign for 20th Century Fox's found-footage superhero thriller Chronicle. A video has been released documenting the concept of this unique marketing strategy and some of the flights. Check it out below.

Thinkmodo's Michael Krivicka had this to say about the viral campaign.

" Since the three main characters of the movie have the ability to fly, we came up with the idea of staging a few "flying people" sightings around NYC. We achieved that illusion by having 3 custom-made aircraft (which were shaped like human beings) fly above designated areas in NYC and NJ."
