Iraqi Airways Flight 163, a Boeing 737-270C, is hijacked and crashes in Arar, Saudi Arabia, killing 63 people.

Iraqi Airways Flight 163 was a Boeing 737-270C, registered YI-AGJ, that was hijacked in 1986. On 25 December 1986, en route from Baghdad's Saddam International Airport to Amman, Jordan, Flight 163 was hijacked by four men. Iraqi Airways security personnel tried to stop the hijackers, but a hand grenade was detonated in the passenger cabin, forcing the crew to initiate an emergency descent. Another hand grenade exploded in the cockpit, causing the aircraft to crash near Arar, Saudi Arabia, where it broke in two and caught fire.

The Boeing 737 is an American narrow-body aircraft produced by Boeing at its Renton factory in Washington. Developed to supplement the Boeing 727 on short and thin routes, the twinjet retained the 707 fuselage width and six abreast seating but with two underwing Pratt & Whitney JT8D low-bypass turbofan engines. Envisioned in 1964, the initial 737-100 made its first flight in April 1967 and entered service in February 1968 with Lufthansa. The lengthened 737-200 entered service in April 1968, and evolved through four generations, offering several variants for 85 to 215 passengers.
