SILT, Colo. (AP) -- A preliminary report on a helicopter crash that killed three people south of Silt last week concludes the helicopter hooked a line strung to protect power lines just before it went down.
The report released Wednesday by the National Transportation Safety Board does not specify what caused the snag to occur. A final report identifying the main cause of the crash is expected within nine months.
Authorities identified the victims as Doug Sheffer, Larry Shaffer and Christopher Gaskill.
Holy Cross Energy spokesman Stephen Casey says aerial surveying of power lines using infrared cameras to find hot spots is common.
