Flydubai flight pilot fight led to Saudi Arabia landing and hijack alert

UPDATE - follow-up to Not 'hjiacked', Flydubai Dubai-Tel Aviv flight lands in Saudi Arabia after pilots brawl: What we know so far: New details show that a physical fight between pilots inside the cockpit caused Flight FZ1073 from Dubai to Tel Aviv to divert to Tabuk in Saudi Arabia.

Flight Path and Emergency Codes

The Boeing 737 MAX 8 carrying 174 passengers transmitted a 7700 general emergency code and a 7500 unlawful interference code near Jordan. Flight-tracking data recorded a steep descent, a sharp climb, and another descent to around 15,000 feet before the aircraft turned west and landed safely in Saudi Arabia.

Security Response and Passenger Accounts

The emergency signals prompted Israel to scramble fighter jets and led Prime Minister Benjamin Netanyahu to hold an urgent security meeting. Passengers reported a violent struggle and shouting near the front of the aircraft, with some witnesses describing a man with a knife and blood present. Israeli media outlets reported that off-duty pilots and passengers helped restrain a crew member, and authorities are investigating whether the incident involved an attempted takeover or a mental health episode.

Context

Commercial aircraft transponders use standard four-digit squawk codes to communicate emergency situations directly to air traffic control systems on the ground. A code of 7700 indicates a general onboard emergency, while 7500 specifically alerts authorities to unlawful interference or a potential hijacking.
