The disturbing memories of the fateful morning of September 2, 1992 still haunt 55-year-old Bini Yajer from Midpu village in Arunachal Pradesh's Dollungmukh Circle, about 110 km from state capital Itanagar. Ms Yajer's husband Bini Tabom was working in his field next to the Dollungmukh range of the Indian Air Force (IAF), the only one for its live fire exercises, including bombing drills in the northeast. That day, when bomb was dropped, Bini Tabom died of shrapnel injuries.
