In Britain's worst mountaineering tragedy, the Cairngorm Plateau Disaster, five children and one of their leaders are found dead from exposure in the Scottish mountains.

The Cairngorm Plateau disaster, also known as the Feith Buidhe disaster, occurred in November 1971 when six fifteen-year-old students from Edinburgh's Ainslie Park High School and their two leaders embarked on a two-day navigational expedition in a remote area of the Cairngorms in the Scottish Highlands.

Hypothermia is defined as a body core temperature below 35.0 °C (95.0 °F) in humans. Symptoms depend on the temperature. In mild hypothermia, there is shivering and mental confusion. In moderate hypothermia, shivering stops and confusion increases. In severe hypothermia, there may be hallucinations and paradoxical undressing, in which a person removes their clothing, as well as an increased risk of the heart stopping.
