The Charkhi Dadri mid-air collision occurred on 12 November 1996 over the village of Charkhi Dadri, to the west of New Delhi, India. The aircraft involved were a Saudi Arabian Airlines Boeing 747-100B en route from Delhi to Dhahran, Saudi Arabia, and a Kazakhstan Airlines Ilyushin Il-76 en route from Chimkent, Kazakhstan, to Delhi. The crash killed all 349 people on board both planes, making it the world's deadliest mid-air collision, the deadliest aviation accident to occur in India, and the third-deadliest aircraft accident in the history of aviation, behind only the Tenerife airport disaster and Japan Airlines Flight 123.
