A Flydubai co-pilot attacked the captain during a flight, a senior UAE official said.

The confrontation happened in the cockpit and used a tool stored there.

Officials say the weapon was the aircraft’s crash axe, a standard safety tool on many jets.

Crash axes are meant for emergency exit and fire, not as weapons.

The article says other men on board stepped in and kept the plane from crashing.

A linked headline calls the people who stepped in mystery men.

Investigators are reconstructing how the co-pilot reached the axe in flight.

An NBC headline in the piece says a UAE official called it an attempted terrorist attack.

Regulators are reviewing cockpit tools, crew vetting, and what they will say about the co-pilot’s state.
