Indian Airlines — Flight IC427

Indian Airlines Flight 427 was hijacked by a lone assailant shortly after departing Delhi for Srinagar on April 24, 1993. The aircraft, carrying 135 passengers and 6 crew members, was taken over by a hijacker armed with two pistols and a hand grenade who demanded to be flown to Kabul, Afghanistan. After Pakistan refused the aircraft entry into its airspace, the plane landed at Amritsar, India. Following a tense 11-hour standoff and failed negotiations, commandos from the National Security Guard (NSG) stormed the aircraft in an operation code-named Operation Ashwamedh. The hijacker was killed within minutes; all 140 remaining hostages were rescued without injury.

Report

Investigation Summary

The hijacking began at 14:43 IST when a passenger, initially identifying himself as Syed Salauddin, claimed to possess firearms and explosives. He forced the flight crew to head toward Kabul, but the aircraft was denied overflight rights by Lahore Air Traffic Control in Pakistan. This forced the Boeing 737 to return to Indian airspace and land at Amritsar at 15:20 IST. During the standoff on the tarmac, the hijacker fired a warning shot that penetrated the aircraft's fuselage to demonstrate his resolve. Negotiations were led by senior government officials, including the Director General of Punjab Police and members of the Crisis Management Group. When the hijacker remained adamant and refused to surrender, the Indian government authorized the NSG's 52 Special Action Group to storm the plane. The commandos entered the aircraft at 01:05 IST the following morning, neutralizing the hijacker before he could detonate his grenade or fire upon the passengers.

Final Conclusions

The incident was concluded as a successful counter-terrorism operation. The lone hijacker, later identified as Jalaluddin alias Mohammed Yunus Shah (also known as Mohammad Yousuf), was the sole fatality. Investigators recovered two loaded 9mm pistols and a live hand grenade from the scene. While the hijacker claimed affiliation with Hizbul Mujahideen, the group denied involvement. The aircraft sustained minor damage from the hijacker's warning shot but was otherwise intact.
