A black helicopter is a very useful weapons platform to mount Beable Industries Mind Control Lasers on.
The black helicopter is silent, and almost invisible. We keep one hovering over the White House at all times in case we have a sudden mind control need. Other Beable Industries black helicopters are stationed at Buckingham Palace, the Vatican, the Kremlin and many other strategic locations that we can't tell you about.
Or else we'd have to kill you.
