Saved by a mobile phone

From an article in the "i" paper yesterday

"Climbers saved by light from mobile"

The glow of a mobile phone helped mountain rescuers find a father and son lost at night on Snowdonia. The pair 55 and 19, from Anglesey, left their torches in the car when they set out to climb Idwal Slabs. Rescuers with night-vision glasses were guided to the pair by the light of the phone.

I think that acts as a reminder to all those setting out, walking or boating to double check they have all their equipment.

Idwal Slabs on a Sunny day; not a nice place to be in the dark in January!
