JERUSALEM (AP) — The identity and motive of the Omani copilot who stabbed his captain on a flight to Israel, causing the plane to plummet dangerously and forcing it to land in Saudi Arabia, remained unknown on Thursday as investigators raced to learn more.

Israeli passengers on the FlyDubai aircraft carrying 174 people from the United Arab Emirates to the Israeli city of Tel Aviv have described how the bloodied Indian captain managed to open the cockpit door to let them in before they grappled with the copilot and stabilized a descent so sharp that the plane’s rudder was torn away.

“We felt helpless, suspended in midair, and I didn’t know who to turn to. But it was all instinct to survive,” one of the responders, Asaf Rajuan, said in a new statement shared by Israel’s presidency.

Israeli Prime Minister Benjamin Netanyahu has said the copilot was arrested. Video shot inside the plane by Shota Musayev, a dentist who treated the captain, shows the copilot on his knees, with his hands tied behind his back.

Saudi and UAE authorities have said little publicly beyond confirming that investigations were underway. Saudi Arabia does not have formal diplomatic ties with Israel, a potential challenge to any joint investigation.

Israeli investigators will join the interrogation of the copilot

Capt. Smit Machchhar, widely praised as one of the heroes of the flight, was reportedly in stable condition, the Indian Embassy in Saudi Arabia said overnight. The condition of the copilot was not clear.

In a CNN interview aired on Wednesday evening, Netanyahu said the attacker was an Omani national and was being interrogated in Saudi Arabia. Asked if there is any indication of Iranian involvement, Netanyahu told Fox News “it’s too early to say.” The prime minister told CNN that Israel had received no specific warning.

U.S. President Donald Trump told reporters at the White House that he and Netanyahu discussed the incident “at length” by phone and it seemed as though the copilot “was perhaps a terrorist or perhaps a whack job.”

Netanyahu said he also spoke with the UAE’s president, Sheikh Mohamed bin Zayed Al Nahyan, who agreed that Israel would join the interrogation of the suspect.

Netanyahu had warned in recent days of unspecified, heightened security threats. The country is a week away from the anniversary of the Hamas-led Oct. 7, 2023, attack on Israel, which has triggered the war in Gaza.

Israel’s foreign ministry said the people on board were from Israel, India and the UAE. The U.S. State Department said four passengers had American citizenship.

FlyDubai has said its flights to and from Israel would be suspended.

School where captain trained calls the safe landing ‘miraculous’

In the chaos that unfolded about two and a half hours after leaving Dubai, the flight descended from 33,000 feet to 17,000 feet (around 10,000 meters to 5,100 meters) in about a minute, before making an erratic circle close to the Jordanian border and landing Tabuk about an hour later, according to Flightradar24, which identified the aircraft as a Boeing 737 Max 8.

The head of the New Zealand flight school where the Indian captain trained, Philip Kean, called it “miraculous in the way that the airplane was never, ever kind of designed for that sort of dive and survive that, the airplane actually didn’t break up completely.”

Already, Trump was praising the U.S.-based Boeing for producing a plane “that was able to withstand G Forces and Strain far beyond what it was designed.”

During the frantic search for a place to land, a person who heard the flight’s communications with air traffic control described the plane being turned away by Saudi Arabia and Jordan before eventually landing in Tabuk, while passengers screamed in the background. The pilot’s voice was trembling as he called “mayday” and said a hijacking was taking place.

The air control operators gave no reason for the refusals. The person who heard the communications spoke on condition of anonymity because they were not authorized to speak to the media.
