Pupils from a Wiltshire school have started final preparations for the annual Ten Tors competition, despite being involved in a helicopter rescue last month.
The students from the John of Gaunt School in Trowbridge were training for the event when they got disorientated by low cloud.
They subsequently got lost and had to be airlifted off Dartmoor.
