The 67 year old man was part of a group of plane spotters making use of the popular "Mach-Loop" vantage points above the Tal y Llyn pass. In muddy conditions he had slipped and fallen a short distance, sustaining a suspected broken femur. Team volunteers assisted the WAST crew with treatment and preparation for extraction from the hill side, and given the potentially serious nature of the injury, the Coast Guard helicopter, Rescue936, was deployed to transfer the man to Ysbyty Gwynedd for further hospital based treatment.
