The aircraft, a Boeing 737 MAX 8, eventually diverted to Tabuk Airport (TUU/OETB) in northwestern Saudi Arabia, where it landed safely with all passengers and crew accounted for. Flydubai confirmed that an "incident" had occurred during the flight but said it was working with the relevant authorities and would provide further information when confirmed.
One of the most alarming aspects of the incident was the aircraft's sudden loss of altitude. Flight-tracking data showed the Boeing 737 descending extremely rapidly from its cruising altitude. It has been reported that the aircraft dropped almost 14,000 feet in less than 30 seconds before the first emergency signal was transmitted. Other tracking reports showed the aircraft descending from approximately 34,000 feet to around 14,000 feet during the incident.
The aircraft subsequently regained control and continued towards Saudi Arabia before landing safely at Tabuk. The aircraft transmitted 7700, the internationally recognised transponder code indicating a general emergency.
More concerning was the reported transmission of 7500. Code 7500 indicates unlawful interference and is commonly associated with a suspected hijacking or other serious security incident. The aircraft later transmitted 7700 again as it approached Tabuk. The combination of the rapidly changing altitude, emergency transmissions and the aircraft changing course towards Saudi Arabia triggered a major security response, including heightened concern in Israel.
What happened inside the cockpit?
This is where the story becomes particularly disturbing — but also where caution is required.
Israeli officials told the media that the two pilots became involved in a physical altercation inside the cockpit. Passenger accounts reported hearing shouting and described a violent confrontation near the front of the aircraft. One passenger's family member said that she had been told a man carrying a knife had forced one of the pilots to the floor and that there was blood present.
For passengers onboard, what began as a normal flight from Dubai to Tel Aviv suddenly became an extraordinary aviation emergency — involving a reported cockpit confrontation, a rapid loss of altitude, emergency transponder codes and an unscheduled international diversion.
The fact that the Boeing 737 MAX ultimately landed safely at Tabuk meant the situation ended without a reported loss of life. Investigators will now have to establish exactly what happened inside the cockpit, why the aircraft descended so rapidly, who transmitted the emergency codes and whether the reported physical confrontation directly caused the aircraft's change in altitude.
The cockpit voice recorder, flight-data recorder, crew interviews and passenger statements will be crucial in establishing the full sequence of events.
