A pilot of a plane traveling from Dubai to Tel Aviv stabbed the other pilot and then apparently tried to crash the plane on Wednesday before being subdued by passengers and crew. The Boeing 737 made an emergency landing in Saudi Arabia, where the unnamed pilot was detained, but not before a steep descent led Israel to send fighter jets over fears of a possible hijacking. Below are some previous examples of plane hijackings and attempted hijackings that could involve pilots or crew members: An off-duty Alaska Airlines pilot attempted to shut down the engines of a Horizon Air plane traveling from Everett, Washington, to San Francisco while traveling in an extra seat in the cabin. The plane was diverted and landed in Portland with more than 80 people. Joseph Emerson told police he was despondent over the recent death of a friend, that he had taken psychedelic mushrooms and had not slept in days. A China Eastern Airlines flight from Kunming, in southwestern China, to Guangzhou, near Hong Kong, crashed into a mountain, killing all 132 people on board. Chinese authorities have not yet released their final investigation report, but data released by American investigators earlier this year suggests that the plane’s engines were deliberately shut down and there was a struggle in the cockpit before the plane went into a nosedive. The co-pilot of a Germanwings plane traveling from Barcelona, Spain, to Duesseldorf, Germany, locked the captain out of the cockpit and deliberately crashed the plane into the French Alps, killing all 150 people on board. Andreas Lubitz had struggled with depression, suffered from insomnia and fear of losing his vision. Read moreThe co-pilot contacted dozens of doctors before the Germanwings accident. The co-pilot of an Ethiopian Airlines flight from Addis Ababa, Ethiopia, to Milan, Italy, hijacked the plane and diverted it to Geneva, Switzerland. Hailemedhin Abera Tegegn, the co-pilot, surrendered to local police and requested political asylum. None of the 193 passengers were injured. The pilot of a Mozambique Airlines plane traveling from the southern African nation to Angola deliberately shot down the plane in a Namibian national park, killing all 33 people on board. Authorities said at the time that Herminio dos Santos Fernandes, the pilot, closed the cockpit door and put the plane on track to crash when the co-pilot went to the bathroom. An EgyptAir flight from Los Angeles to Cairo plunged into the Atlantic Ocean off Nantucket, Massachusetts, killing all 217 passengers and crew on board. American investigators concluded that the co-pilot, Gameel Al-Batouti, put the plane on a crash course while the captain was in the bathroom. He then shut down the engines while the captain returned and struggled to right the plane. Egyptian authorities, however, disputed the findings and concluded in their own investigation that mechanical failure was to blame. A SilkAir flight from Jakarta to Singapore crashed near the Indonesian city of Palembang, killing all 104 people on board. Indonesian investigators concluded that “illegal interference” likely caused the new model Boeing plane to crash in fair weather. Their report found that the pilot, Tsu Way Ming, “was in the process of leaving the cockpit or intended to do so” before the cockpit voice recorder was turned off. Authorities also said the pilot “was facing financial issues and had experienced several disciplinary actions from the company,” including a demotion. A pilot crashed a Royal Air Maroc flight from Agadir, Morocco, to Casablanca in the Atlas Mountains just 10 minutes after takeoff, killing all 44 people on board. Investigators determined that Younes Khayati turned off the autopilot and sent the plane into the ground while the co-pilot tried in vain to intervene. The Associated Press reported at the time that it was “the pilot’s deliberate desire to end his life.” A union representing pilots disputed the conclusions. An off-duty FedEx flight engineer attempted to hijack a company cargo plane traveling from Memphis, Tennessee, to San Jose, California, while traveling as a jump-seat passenger. Auburn Calloway attacked the flight crew armed with a hammer and a rifle. The crew subdued him and landed the plane safely, even though those who confronted Calloway suffered serious injuries. Investigators said Calloway intended to crash the plane after facing possible disciplinary action. A Japan Airlines flight from Fukuoka to Tokyo crashed into Tokyo Bay just as it landed, killing 24 of the 174 people on board. Investigators said there was a fight in the cockpit when the pilot, Seiji Katagiri, put the engines in reverse. They also later determined that Katagiri, who survived the crash, had been deemed fit to fly even after having a history of mental illness, including paranoid schizophrenia. (FRANCE 24 with AP)
