The basic question I have is why the first response to the Hikers was the Helicopter and not the Ground Rescue Team?
I googled the general location and see from the Sat View there are easily discerned trails in the area.
The Accident Report noted the Hikers had Torches that were seen on the FLIR.
No mention was made of any injury to the hikers or why they felt they needed rescue.
The Report stated the aircraft notified the ground team and they then went to the Hikers and walked them out on foot.
