Maj. Gen. (retd) Mahmud Ali Durrani, who was suspected by many circles within Pakistan and also by the then United States Ambassador to India, John Gunther Dean, for being "extraordinarily insistent" with President Zia to visit the demonstration, is considered to be the prime suspect in the incident. He claimed later that reports of Israeli and Indian involvement in Zia's plane crash were only speculations and he rejected the statement that was given by former president Ghulam Ishaq Khan that the presidential plane was blown up in the air. Durrani stated that Zia's plane was destroyed while landing.
