I think this article was from last year, but I see these things flying over the Caney Fork all the time and always kinda wondered..."what if???"
A U.S. Marine helicopter may have narrowly averted disaster here last weekend after severing a pair of static lines along a high-voltage TVA transmission system in the vicinity of Center Hill Dam.
The system was in fact out of service at the time and therefore not carrying a charge, according to TVA officials.
The incident occurred around mid-morning on Saturday. Residents in the area heard and observed at least one military whirlybird flying low to the terrain above wooded hills and hollows not far from the Caney Fork River, about a mile downstream from the Corps of Engineers dam in northern DeKalb County.
The aircraft was reported by a Marine Corps spokesman to be an AH-1W SuperCobra attack helicopter. Its estimated value is more than $10 million.
The helicopter collided with the TVA lines along a 1400-foot span between two rugged hilltops a short distance from Highway 141. It was able to continue flying.
