New visuals show passengers handcuffing FlyDubai co-pilot Hammam al Hammami after he attacked the captain and attempted to take control of the Israel-bound flight. Captain Smit Machchhar opened the cockpit door despite his injuries, allowing passengers to overpower and restrain the co-pilot before handing him to Saudi police. Meanwhile, investigators are probing Al Hammami’s aviation career, reported extremist material, time in Syria, online activity and possible radicalisation as questions grow over how he entered the cockpit.
