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 NYC 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.
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]
