It also found violations of standard operating procedures. Earlier, military sources said the probe found that the ‘Identification of Friend or Foe’ (IFF) system on-board the helicopter was switched off and there were “vital gaps” in communication and coordination between the ground staff and the crew of the chopper. The helicopter crashed in Budgam around 10 am on February 27 when Indian and Pakistani fighter jets were engaged in fierce aerial combat in Nowshera, a day after India’s airstrike on a Jaish-e-Mohammed terrorist training camp in Balakot in Pakistan. The helicopter went down around 10 minutes after taking off.
