What we're learning about the FlyDubai co-pilot who allegedly stabbed the captain and tried to crash the plane

One day after a FlyDubai co-pilot made a violent attempt to crash the passenger aircraft and was subdued by passengers and other crew members, questions about his identity and motive continued to swirl Thursday. The flight from Dubai to Tel Aviv was approaching Israel when the co-pilot allegedly stabbed the flight captain and attempted to crash the aircraft, Israeli Prime Minister Benjamin Netanyahu has said. The captain was able to fight off the co-pilot long enough to unlock the cockpit door. Passengers then overpowered the co-pilot, and two off-duty pilots who were on the flight managed to gain control of the aircraft and make an emergency landing in Tabuk, Saudi Arabia.There were 174 people aboard the plane. No passengers were seriously injured in the incident. The pilot sustained stab wounds in the attack.
