Iranian President Ebrahim Raisi was likely traveling on a Bell 212 helicopter that began operating in the late 1960s, according to military analysts. The helicopter, first produced in the United States and later in Canada, has a history dating back to the late 1960s when it was utilized by the US military before being introduced in commercial form during the Shah's rule in 1976.
One of the key challenges associated with this aging helicopter model is the difficulty in obtaining spare parts. Retired US Air Force colonel Leighton highlighted that spare parts would have been a significant issue for the Iranians due to the age of the aircraft and potential sanctions affecting the procurement process.
