Volo Alitalia 112 (義大利航空112號班機空難)

On 5 May 1972, the aircraft I-DIWB of Alitalia (a Douglas DC-8-43) started the flight AZ 112 from Rome to Palermo, taking off 36 minutes late. Captain Roberto Bartoli was in charge of the radio assistance, while First Officer Bruno Dini flew the aircraft. Gino Di Fiore served as the flight engineer.
The flight AZ 112 contacted Palermo Approach around 9:10 PM stating to be at 74 nautical miles (137 km) from VOR (which is installed on Mount Gradara, above the municipality of Borgetto, with a frequency of 112.3 MHz, around 10 miles (16 km) south of the airport of Punta Raisi). Control tower replied with meteorological data (five knot wind, five kilometer visibility, cumulus clouds at 1,700 feet and cirrus clouds at 20,000 feet) and then authorized the descent, instructing the aircraft to report their position when they reached an NDB radio beacon designated PRS at an altitude of 5,000 feet. The times and locations have been precisely recovered from the recorder of Rome Control, which had a time recorder, while Palermo Approach did not.
Commander Bartoli then made the following transmission to air traffic controller Sergeant Major Terrano:

Contact between flight AZ 112 and the control tower was lost, the only communication was in English between the DC-8 itself and an Ilyushin Il-18 that was waiting for take-off, the tower tried to contact AZ 112 but received no response. Around 10:23–24 PM, the aircraft (coming from Ponente-lato Terrasini) hit a crest 935 meters (1,980 feet) high, about 300 feet (91 m) below the top of the mountain, and slid for a long time on the ground with its wings, its fuselage, and its four engines, until it disintegrated in the successive hits against the rocks of the crest. Part of the debris and bodies of the victims rolled on the mountain side…

Of the 115 passengers and crew, almost all were Italian; the only known foreigners aboard were a Belgian stewardess, three British people and a French couple. The travellers were, for the most part, returning home to vote in the Italian national elections that weekend. Among the victims of the crash were the noted film director Franco Indovina (who was working on a film about Enrico Mattei) and Cestino Vycpalek, the son of the then-coach of the Juventus team, Čestmír Vycpálek. The victims also included Palermo deputy attorney general Ignazio Alcamo (who had ordered the forced residence of Francesco Vassallo, a construction worker with ties to the Sack of Palermo and Antonietta Bagarella, the future wife of Italian mafia leader Salvatore Riina); Angela Fais, the editorial secretary of L'Ora and Paese Sera and a friend of Giovanni Spampinato; Letterio Maggiore the former doctor of bandit Salvatore Giuliano (Maggiore also testified in the trial for the Portella della Ginestra massacre); Lidia Mondì Gagliardi, one of Palermo Airport's first passengers; and Alberto Scandone a journalist for the Italian Communist Party. The crash left 98 children orphaned and 50 spouses widowed.

The trial represented the official version of events. The trial targeted the pilots for not following the guidelines of the flight controllers. The reason for the crash was labeled as 'pilot error' and a controlled flight into terrain (CFIT) (describes an unintentional crash by an airworthy aircraft into the ground).
There is another version of the accident held by some of the victims' relatives. Mrs. Maria Eleonora Fais, sister of Angela Fais, who died in that plane, was able to find, after many years, the report of the Vice-Chief of Police Giuseppe Peri that says that the plane exploded because of a bombing. Peri accuses an alliance of people having ties with the Mafia and with a subversive group from the Right with the responsibility for this bombing. Three days after the accident the political elections would be held in which a strong rise of the Right was foreseen. The National Association of Italian Pilots (ANPAC) sided with the pilots, refusing the possibility of a mistake due to their long experience and because the accusation of an intoxication to prove their "exclusive" responsibility had been denied. Other problems have been raised on the bad position of the airport of Punta Raisi. (On the position of the airport, see the accusations raised by Giuseppe Impastato).
There is an urban legend that in the crash of Montagna Longa a mythical first wife or partner of the songwriter Francesco De Gregori found her death. But it is only an unfounded conjecture deducted from the words of the song Buonanotte Fiorellino, which seems to make allusion to the tragedy. In reality, the song is inspired by "Winterlude" of Bob Dylan.
In March 2012, a Carabinieri general whose brother died in the accident asked the Catania prosecutor's office to reopen the investigation into the…
