Sources tell Action News the balloon is in two pieces - the tail section and the a second larger section- in Montour County.
NORAD says a portion of its tail fell off from the blimp and also landed in Columbia County, it has been secured by local law enforcement
State police are in the area of Yeagle Road and Muncy Exchange Road in Anthony Township and have the area closed off awaiting defense department officials.
NORAD said at 12:20 p.m. Wednesday the balloon known as a Joint Land Attack Cruise Missile Defense Elevated Netted Sensor System (JLENS), broke free from its mooring station in Aberdeen, Maryland.
The balloon is described at 37 meters in diameter and apparently looks like a blimp. A large cord is hanging from the balloon.
The balloon traveled through Lancaster and Lebanon counties and then into Columbia and Montour.
Earlier, a Twitter user, who captured video of the balloon, had said it landed in Bloomsburg, Pa.
Two F-16 Fighter jets from Atlantic City Air National Guard Base were monitoring the balloon.
PPL Electric Utilities reports the tether attached to the aircraft caused widespread power outages across Pennsylvania.
PPL reports that the damage appears most extensive in Columbia and Schuylkill counties.
There were approximately 30,000 residents without power at the peak of outages and approximately 15,000 remain without power.
FAA officials were working with the military to ensure air traffic safety in the area, and has referred all questions to NORAD.
NORAD released a statement on the incident, in which they explained the JLENS program. The statement reads in part:
- "JLENS is a supporting program of the Army and Joint Integrated Air and Missile Defense, providing persistent, over-the-horizon radar surveillance and fire control quality data on Army and Joint Networks. It enables protection from a wide variety of threats to include manned and unmanned aircraft, cruise missiles, and surface moving targets like swarming boats and tanks. A JLENS system consists of two aerostats: a fire control radar system and a wide-area surveillance radar system. Each radar system employs a separate 74-meter (243 feet long) tethered aerostat, a mobile mooring station, radar and communications payloads, a processing station, and associated ground support equipment. The JLENS aerostat will fly at an altitude of up to 10,000 feet above sea level."
