Federal investigators say a helicopter crash that killed three people south of Silt last year likely stemmed from the pilot failing to see a power line or properly prepare for the flight.
A National Transportation Safety Board probable-cause report says pilot Doug Sheffer probably didn't spot the line before hitting it because he was flying into the sun. The January 2014 crash killed him and two passengers, Larry Shaffer and Christopher Gaskill, as they surveyed power lines in the town of Silt.
