The New York City Police Department says that -- if necessary -- it has weapons that could take down an airplane, though it sounds like the emphasis is small airplanes, the AP reports. (Anything bigger would be an issue for NORAD, sources tell MSNBC.)
What kind of weapons? Surface-to-air missiles? A swarm of trained pterodactyls? According to the New York Post, they would use a Barret .50-caliber rifle, which they favorably compare to a bazooka.
