Possible Attempted Terror Attack in New York: Close call as planes nearly collide over Westchester

Investigators Exclusive: Close call as planes nearly collide over Westchester

WESTCHESTER COUNTY (WABC) -- Eyewitness News has learned that two planes nearly collided in mid-air over Westchester County over the weekend, and now, two passengers are speaking out about the scare.
It's an Investigators' exclusive.
JetBlue Flight 94 had begun its descent to Westchester County Airport Sunday afternoon when its collision-warning system alerted inside the cockpit. An unidentified plane flying in busy commercial airspace was closing in on them.
Shortly after, the controller told them to change course. At some point, that unidentified plane got close, much too close, to the passenger-filled JetBlue plane.
"I'm looking out the window, and then this white airplane is now coming at our airplane," passenger Megan Sikorski said. "I turned and buried myself in my mom's lap and grabbed the guy next to her. And our plane went up, and you could hear the woosh of the other airplane underneath us."

Video report at link. The print report characterizes the rogue plane as "joyriding". WTF?
Dry run?
