Video: 1WTC is emitting an eerie howl

Ever since the 1 World Trade Center building was completed, nearby residents have noticed that it emits an eerie howl in the wind. Some say the sound is the cries of the ghosts of 9/11, and while this is clearly just a case of the physics of wind and sound generation, when you hear the noise, you can kinda see their point.
