A Flydubai flight traveling from Dubai to Tel Aviv landed safely at Saudi Arabia’s Tabuk airport on Wednesday after triggering emergency and hijack alerts during a dramatic cockpit incident.

Flight FZ1073, carrying around 180 people, was heading toward Ben Gurion Airport when it transmitted the international emergency code 7700 and later the 7500 code, which indicates hijacking or unlawful interference. The aircraft was diverted from its route and eventually landed at Tabuk, where Saudi security forces surrounded the plane.

Israeli authorities initially struggled to establish contact with the aircraft and scrambled fighter jets amid fears that the flight had been hijacked.

The exact sequence of events remains under investigation. Israeli officials and media reports said the emergency signals were apparently triggered by an altercation between the two pilots inside the cockpit.

The Times of Israel, citing passengers and Hebrew-language media reports, reported that one pilot allegedly attempted to crash the aircraft and was stopped by the second pilot with assistance from passengers. Channel 14 reported that one pilot may have attempted suicide and allegedly forced the aircraft into a rapid descent before the second pilot intervened.

Flight-tracking data showed unusual altitude changes during the flight. The aircraft reportedly climbed to about 21,650 feet before descending below 14,000 feet and later stabilizing around 15,000 feet.

Passengers quoted by Israeli media described panic on board, including shouting near the cockpit and a steep descent. Some also reported seeing blood in the cockpit and claimed that a pilot had been stabbed. These accounts have not been independently confirmed.

Flydubai later confirmed that FZ1073 had experienced an “incident” and landed safely in Tabuk. The airline said all passengers were safe and accounted for and that it was cooperating with relevant authorities.

The reported hijack alert, cockpit confrontation and unusual flight movements are expected to remain under investigation.
