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. Investigators believe that the crew had 3 miles visibility and did not adhere to the established vectors issued by air traffic control. It remains the deadliest single-aircraft disaster in Italy, and the second-deadliest behind the Linate Airport disaster in 2001. The incident is the worst in Alitalia's history.

A memorial has been erected at the site of the crash.
