A Flydubai flight from Dubai to Tel Aviv broadcast emergency codes, plunged sharply, and diverted to land in Saudi Arabia. What is known about the incident, what is still controversial, and what the code 7500 means, which indicates illegal interference with the plane.
A Flydubai flight from Dubai to Tel Aviv first transmitted a general emergency code and then code 7500, indicating unlawful interference, plunged sharply and diverted to land in Tabuk, Saudi Arabia. While the investigation is ongoing and reports of what happened in the cockpit are still partly contradictory, the incident illustrates how four digits on a transponder can activate an entire array of air traffic controllers, security officials and fighter jets in seconds.
Update, September 30, 2026, evening: The Flydubai rescue plane, which was sent to Tabuk, Saudi Arabia to pick up the flight's passengers, landed at Ben Gurion Airport. This ended the passengers' journey after the original flight was forced to land in Saudi Arabia following the unusual incident in the cockpit.
Update, September 30, 2026, 17:50 PM: Prime Minister Benjamin Netanyahu said one of the pilots stabbed his colleague and apparently tried to crash the plane, and that the suspected pilot had been arrested in Saudi Arabia. According to Netanyahu, a passenger and a crew member entered the cockpit and overpowered the attacker; other crew members then flew the plane, as reported inAP AgencyDefense Minister Israel Katz said that According to initial information in Israel's possession This was an attempted attack, and that passengers transferred control to another crew of pilots who were on the flight. This publicly reinforced the report that additional pilots were present, but their exact number, identity, or reason for flying as passengers were not confirmed. Flydubai said that the reasons and motives are still unknown and that an official investigation is underway. Tabuk Airport confirmed that both pilots were injured and hospitalized. Therefore, the attempted crash and its classification as an attack are at this stage the assessment of senior Israeli government officials, and not the final findings of the investigation.
What is confirmed is that flight FZ1073, which took off from Dubai en route to Ben Gurion Airport, first transmitted code 7700 – a general emergency – during the incident, and then code 7500, which is used to indicate illegal interference with the aircraft. According to Flightradar24, the code was later changed back to 7700. The plane made a very sharp descent, deviated from its course and landed safely in Tabuk in northwestern Saudi Arabia. All passengers were reported safe.
Four digits that tell the visitor what's going on
A transponder is a transmitter on an aircraft that allows air traffic control systems to identify the aircraft and receive information from it. During normal flight, an aircraft is assigned a four-digit code, known as a Squawk Code.
Three codes reserved for emergencies are particularly well-known:
- 7500 – Illegal interference with an aircraft, and in practice is mainly identified with suspicion of hijacking or takeover.
- 7600 – Loss of radio communication.
- 7700 – General emergency.
Selecting code 7500 triggers a special alert for air traffic controllers. The importance of the code is that it allows the crew to transmit a distress signal even when they cannot explain over the radio what is happening in the cockpit.
What does the flight controller do when 7500 appears?
According to standard aviation procedures, the controller asks the pilot to confirm the transponder code. If the code was entered incorrectly, the pilot can correct it. If the pilot confirms the code, or if there is no clear response, the controller may treat the situation as a real security incident, continue to track the aircraft, and pass the information on to security authorities.
In other words, even silence can carry operational significance.
Why does 7700 sometimes appear first?
Code 7700 is the most general emergency code. It tells air traffic controllers that something serious is happening, without immediately specifying what the incident is. In a rapidly developing situation, the crew may choose to first flag a general emergency and then move on to a more specific code.
In the case of FZ1073, public tracking data showed a sequence of 7700, followed by 7500, and then back to 7700. The sequence itself indicates a change in the assessment of the situation inside the cockpit, but does not reveal who activated the code or why.
The sharp dive – and what can we learn from it?
According to Reuters and published tracking data, the plane lost about 14 feet in altitude in less than half a minute. This is a very unusual change in the flight profile, which has increased concerns that this was a serious incident in the cockpit.
However, tracking data alone cannot determine the cause of the descent: whether it was a deliberate action by one of the crew members, a response to a struggle in the cockpit, a malfunction, an order from air traffic control, or the result of an action designed to regain control of the aircraft. Only flight recorder data, crew and passenger testimony, and the official investigation can provide the answer.
Why are fighter jets launched?
When a civilian aircraft transmits code 7500, the issue is no longer just aviation safety but also national security. Authorities need to quickly determine whether the aircraft is under control, where it is headed, and whether it could pose a threat.
Fighter jets can approach the plane, visually identify it, attempt to establish contact, escort it to a landing, and move it away from sensitive areas. In the current case, it was reported that Israel scrambled fighter jets following the initial warning.
Photos and testimonies from social media
During the day, photos and testimonies from passengers were circulated on social media, including documentation of people covered in blood. This material supports that a violent incident occurred on the plane, but does not in itself provide an answer to the question of who attacked whom or what exactly happened in the cockpit. Such evidence may be important, but it must be examined against official sources and other evidence.
An emergency code is not an investigation conclusion.
The activation of Code 7500 is a very serious signal, but it is not proof in itself that a plane has been hijacked. She says that at that moment someone in the cockpit signaled illegal interference. Only after landing, collecting evidence and examining the plane's data can it be determined what really happened.
Currently, the most well-founded explanation is that a violent event occurred inside the cockpit, triggering the emergency codes, the abnormal dive, and the diversion of the flight to Saudi Arabia. The exact details of who was involved and how the plane was restored to control are still being investigated.
What does code 7500 mean?
This is an international transponder code indicating unlawful interference with an aircraft, and is usually associated with suspected hijacking or takeover.
What is the difference between 7500 and 7700?
7700 indicates a general emergency. 7500 is a more specific signal for illegal interference.
What is code 7600?
7600 indicates loss of radio communication between the aircraft and flight control.
Does activating 7500 prove that a plane has been hijacked?
No. It triggers an immediate emergency response, but the significance of the incident is determined only after investigation.
