Chennai, June 27: Over 35 years after a flight sergeant was presumed missing after an Air Force plane in which he and 90 others were flying in disappeared over the Rohtang Pass near the Indo-Pakistan border, the officer Somasundram's wife Vijayalakshmi, has petitioned the State Human Rights Commission to make concerted efforts to trace the missing Flt. Sgt. In her petition filed yesterday before the State Human Rights Commission, the 66-year old Mrs Vijayalakshmi Somasundaram said her husband was four years older than her. She said, "The time is evidently short. I would like to pass away either as Mrs Somasundram or the widow of Mr Somasundram which is only in your hands." On February 7, 1968, when the occupants of the aircraft, including a crew of six were returning from Leh to Chandigarh, all contact with the aircraft was lost while it was over the Rohtang Pass. Since then it has been presumed that the aircraft had crashed and all the occupants were dead. Till date the cause for the disappearance was yet to be established, it is understood. A certificate of official presumption of death of all the persons on the aircraft was issued nine months later. Bureau Report
