A year later, Saadati was transferred to the engineering department of the Air Force Headquarters and worked in that center for two and a half years. At the same time, with the help of the Jalalzadeh brothers, he registered a company called Nolco, and through the Jalalzadehs, he met Mehdi Rezaei and started cooperating with the People’s Mojahedin Organization as a sympathizer. Saadati was one of those who died from the attack of SAVAK on the Mojahedin organization in 1350 Shahrivar, which led to the arrest of a large group of this group’s forces, but in May 1351, following the arrest of Mehdi Rezaei, Saadati was also arrested along with his wife, Nahid Jalalzadeh. Saadati was sentenced to life imprisonment in court and joined Massoud Rajavi’s group in prison.
