COUNCIL BLUFFS, Iowa - No one was injured when a medical helicopter hit a power line while lifting off from the scene of an accident in Council Bluffs. Pottawattamie County Sheriff Jeff Danker says the helicopter was called to help a man who had fallen off a ladder Wednesday evening. Danker says the accident happened when the Life Net helicopter was taking off to transport the man to Creighton University Hospital in Omaha. Danker says the chopper's tail rotor clipped a power line owned by Mid-American Energy. That caused a loud pop and a blue flame, and sparks from the power line caused a small brush fire. The chopper landed safely but sustained some damage. Danker says an ambulance took the fall victim to the hospital.
