Several hundred feet of power line clipped by a low-flying helicopter fell across Interstate 81 Wednesday evening, clogging traffic for nearly 14 miles for over two hours.
Ironically, the aircraft was owned by Air2, a company based in Timonium, Md., that provides line transmission aerial service support and maintenance to power companies.

It's not far to fall.
