Meet the heroes behind the flight: As chaos erupted in the air, four men sprang into action to help stop the Flydubai attacker and keep the aircraft under control. Asaf Rajuan used headphone cables to restrain the attacker while Tzvika Manes jumped in and helped tie him down. Yaniv Hayon worked to stabilize the aircraft after it plunged 14,000 feet. And Captain Smit Machchhar fought off the attacker and managed to open the cockpit door even after being stabbed.
