A plumber, a dentist and others are being hailed as heroes after a dramatic incident on a flight from Dubai to Tel Aviv. The copilot attacked the captain, causing chaos as the plane plunged. Passengers rushed to the cockpit. A plumber, recalling air disaster films, briefly handled the controls until he said two traveling British pilots stabilized the plane. Meanwhile, a dentist attended to the injured captain. Within minutes of their arrival in Tel Aviv after an emergency landing in Saudi Arabia, Hayoun was meeting Israel's prime minister while still wearing his bloodied shirt.
