Alitalia Flight 112 crashes into Mount Longa near Palermo, Sicily, killing all 115 aboard, making it the deadliest single-aircraft disaster in Italy.

Alitalia Flight 112 was a scheduled flight from Leonardo da Vinci Airport, in Rome, Italy, to Palermo International Airport in Palermo, Italy, with 115 on board. On 5 May 1972, it crashed into Mount Longa, about 3 miles (4.8 km) southwest of Palermo while on approach to the airport, killing all 115 passengers and crew onboard. Investigators believe that the crew had three miles visibility and did not adhere to the established vectors issued by air traffic control, while according to an independent investigation the accident was caused by an explosion on board.
