A FlyDubai plane headed to Israel made an emergency landing on Saudi Arabia after one of the pilots stabbed his copilot and tried to crash the plane. Luckily, he tried to push the stabbed copilot out of the cockpit which allowed passengers to rush in and subdue him, but the plane lost 17,000 feet in altitude during the altercation.
