When the controller called KZA1907 again, he received no reply. He tried to warn of the other flight's distance, but was too late. The two aircraft collided, with the tail of KZA1907 cutting through SVA763's left wing and horizontal stabiliser. The crippled Boeing quickly lost control and went into a rapidly descending spiral with fire trailing from the wing. The Boeing broke up before crashing into the ground at a nearly supersonic speed of . The Ilyushin remained structurally intact as it entered a steady but rapid and uncontrolled descent until it crashed in a field. Rescuers discovered four critically injured passengers from the Ilyushin, but they all died soon afterwards. Two passengers from the Saudia flight survived the crash, still strapped to their seats, only to die of internal injuries soon after. In the end, all 312 people on board SVA763 and all 37 people on KZA1907 were killed.
