A group of Britons who became stranded in the Himalayas with a seriously ill climber were saved after making a distress call to Dorset.
Four hikers and 10 local porters were climbing a 16,000ft (4876m) mountain in Nepal when one of the men became ill.
The team called the organisers of the trip who are based in Sherborne to coordinate their rescue.
But they had to wait 72 hours for a helicopter because riots in Nepal had caused all aircraft to be grounded.
Trek leader Michael Bromfield used his satellite phone to contact his Great Walks of the World headquarters in Sherborne.
Andy Broom, a senior manager at the adventure company, co-ordinated the emergency rescue but could not get any helicopters to the scene because Nepalese government had imposed a curfew following large scale rioting.
Mr Broom finally managed to get a Nepalese Army helicopter to fly to the men's rescue.
Mr Bromfield said: "One of the men got a really serious attack of diarrhoea and vomiting and was seriously dehydrated.
"We stopped where there was a little bit of shelter and erected two tents by a shepherd's hut.
"There was a complete white out. It snowed for 24 hours. When we woke up the next morning there was the best part of 5ft of snow. The hut had snow up to the roof."
"At one point one of the guys lost it a bit and said there was a revolution going on in Nepal, no one was coming to save us."
The group, who were all unharmed, are planning to continue their trek along the north side of Everest.
The five-week adventure began on 6 April with the British trekkers paying £3,500 to explore the high-altitude Himalayas in Nepal and Tibet with Mr Bromfield's travel firm.
They had flown to Kathmandu where 10 porters joined them for the trek through the Upper Langtang Valley.
Mr Bromfield added: "The real hero as far as I'm concerned was Andy for co-ordinating it all back in rural Dorset."
