Why Four Pilots Helped Save Flydubai Flight After Attack

Four pilots were on the plane because the airline worried that the flight might need to take a longer route.

This could have made the original pilots work longer than allowed.

During the flight, the copilot allegedly stabbed the captain.

The plane quickly lost about 14,000 feet of altitude.

Passengers and crew fought the suspected attacker and tied him up.

One of the extra pilots moved to the cockpit and flew the plane.

Another extra pilot was reportedly shocked at first.

The injured captain was treated by a dentist who was also a passenger.

The plane landed safely in Tabuk, Saudi Arabia, where authorities detained the suspect.

Israeli officials called it terrorism, but Flydubai said the motive had not yet been established.
