Flying People in New York City - YouTube

Three people were spotted flying around the skies of lower Manhattan last Friday, causing dropped jaws from onlookers.

But while it appeared to be flying "death eaters" of  the "Harry Potter" series, it actually turned out to be a clever piece of viral marketing for this week's upcoming film "Chronicle."

In an interview to yahoo! James Percelay, the co-founder of Thinkmodo said he and his partner Michael Krivicka were approached by 20th Century Fox, the studio behind "Chronicle," and they came out with a plan for the viral video.

Those aren't people in the air, but some very intricately designed radio-controlled airplanes. Percelay has not disclosed who exactly was piloting the planes in the video. He only said: "They are expert AMA (Academy of Model Aeronautics) members with amazing skills."
