Ten years after the Sept. 11 attacks on the World Trade Center, Police Commissioner Raymond Kelly said the NYPD now has the capability to take down a plane if necessary.
In a “60 Minutes” interview that airs on CBS Sunday night, Kelly said the department’s counterterrorism unit is prepared to thwart an oncoming plane if it’s deemed a threat.
“Well, it’s something that’s on our radar screen,” Kelly told Scott Pelley of the news show. “I mean in an extreme situation, you would have some means to take down a plane.”
He did not elaborate on what methods the NYPD would use but a police source said, “NYPD Aviation has weapons that caould be deployed with that capability.”
Kelly discussed the precautions made before the General Assembly meeting at the United Nations this week, just days after a threat was made to attack the city on the 10th anniversary of 9/11.
