A FlyDubai commercial flight carrying dozens of Israelis from Dubai to Ben Gurion airport was forced into an emergency landing at Tabuk airport in north-western Saudi Arabia on Wednesday after an apparent violent altercation between its pilots. The plane transmitted three emergency signals while over Jordanian airspace, one indicating possible unlawful interference — the aviation code word for hijacking. The aircraft dropped roughly 16,000 feet in two minutes during the incident. Passenger accounts, relayed through Israeli media and relatives, describe a scene of chaos: one pilot allegedly stabbed another and attempted to force him from the cockpit, prompting Israeli passengers to rush in and physically subdue the attacker as the plane plunged. Yasmin Abu Kaiss told Reuters her daughter heard screaming and saw blood everywhere and a man with a knife pinning a pilot to the floor. Pictures of a blood-covered passenger shirt circulated in Israeli media. None of these accounts have been independently verified. Israel's response was immediate and heavy. Fighter jets were scrambled on fears of a hijacking attempt targeting Israelis. The head of the Israeli military, Lt Gen Eyal Zamir, postponed a planned visit to the United States next week that was to include meetings with US joint chiefs of staff and the head of US Central Command. A spokesperson for Netanyahu's office initially said the diversion was not a hijack attempt; authorities later said they were investigating whether it was an attempted suicide by a pilot or a deliberate attack on Israelis. The timing sharpened political nerves. Benjamin Netanyahu had warned just days earlier of indications that an attack would be carried out during Israel's October elections. The Israeli military said it had no intelligence of a planned attack. Israel has not experienced a hijacking or airborne attack since the wave of Palestinian militant operations in the 1960s and 1970s, and maintains among the strictest airport security regimes in the world — including pre-boarding checks on Israel-bound flights. The incident lands on a diplomatic fault line. Flights between Dubai and Israel began only after the 2020 normalization of ties. Israel has no diplomatic relations with Saudi Arabia, though a medical-emergency landing in Riyadh occurred in 2025. The Saudi aviation authority confirmed all passengers were safe and both pilots were hospitalized. The Israeli air force was awaiting Saudi permission to fly the stranded passengers home. A subsequent FlyDubai flight to Tel Aviv turned back to Dubai mid-air. FlyDubai confirmed the incident on flight FZ 1073, saying teams were working with relevant authorities and that further updates would follow. The carrier offered no additional detail on the cause or nature of the cockpit fight. What remains unresolved is the most consequential question: motive. The Israeli investigation is reportedly weighing pilot suicide versus a targeted attack. Until that question is answered, the incident functions as a stress test of the Gulf-Israel aviation corridor — a corridor that exists because of a diplomatic normalization barely five years old, overflying countries with no formal ties to Israel, and now demonstrated to have no redundancy when something goes wrong at 35,000 feet.
