This is the best prank you can pull on an entire city. The marketing team behind the movie Chronicle tried its hand at viral marketing by flying three human-shaped RC planes around New York City to make it look like real people were magically flying. From the ground, it really looked like you were watching a superhero do its flyin' thang. Video!
I WANT TO BELIEVE. I'm also glad I didn't see this in real life because I probably would've freaked out. [New York Observer]
