Investigation after 328-foot turbine buckles at wind farm in County Tyrone despite only light winds A 328-foot tall wind turbine worth more than £2 million pounds has buckled and collapsed on a mountainside in Northern Ireland. Unconfirmed reports suggested the blades of the turbine had spun out of control - despite only light wind speeds - before the structure came crashing to the ground on Friday. Locals claimed the sound of the turbine hitting the mountain could be heard up to seven miles away from the Screggagh wind farm, near Fintona in County Tyrone.
