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 5 km (3 mi) south-west of Palermo while on approach. Investigators believe that the crew had 3 miles (4.8 km) visibility and did not adhere to the established vectors issued by air traffic control. It remains the deadliest single-aircraft disaster in Italy.
