Alex Dorr, a search and rescue pilot who was part of the team that found missing British backpacker Sam Woodhead, told ITV's Daybreak a helicopter was "scrambled out last night" as they searched in the dark with night-vision cameras in a bid to find him quickly.
He described the area Woodhead went missing in as "very harsh and unforgiving".
Dorr added: "Not that long ago we had a guy who was missing for a much shorter time and he passed away from dehydration."
