I am using the helicopter only in case of an emergency," he added.He said 24 helicopter sorties were undertaken this winter in Lahaul-Spiti district in which 606 people, including 20 patients, were airlifted till February 15.The chief minister said priority to undertake a sortie is given for emergency evacuation of patients.Thakur demanded that a special helicopter should be deployed for evacuating people in Lahaul-Spiti district only.The Lahaul and Spiti valleys in Lahaul-Spiti and Pangi in Chamba district remain cut off for at least five months from December owing to heavy snowfall.The road connectivity reopens once the snow starts thawing after mid-April.
