From the AP, via KXMB.com:
MCCALL, Idaho -Four people were injured when lightning struck a firefighting helicopter in central Idaho while it was on the ground.
None of the employees of Siller Brothers, Inc., a contract firefighting company, suffered life-threatening injuries in Tuesday evening’s incident, but they were transported to hospitals in the region for treatment.
The Sikorsky S64E Air-Crane helicopter was on a national contract with the Payette National Forest to help fight forest fires in the region.
The incident Tuesday night at about 8:45 a.m. took place just as the four crew members were doing end-of-day maintenance.
They were tying the chopper down as high winds hit the area following heavy rain and lightning.
Damage to the aircraft is still being surveyed.
