An aerostat, a type of tethered balloon, untethered at a military facility in Maryland, drifted high in the air and landed in Pennsylvania.By Sebastian Martinez | October 28, 2015
The balloon was one of two at the Aberdeen Proving Ground Army facility, and it broke free Wednesday morning, trailing more than 6,000 feet of cable.
The aerostat was part of a NORAD missile defense system, and it's supposed to detect incoming cruise missiles. (Video via Raytheon)
