Spatuzza's claims mark the first time a Sicilian mobster has revealed Cosa Nostra's aim of using remote-controlled aircraft for murder.
In 1992, the mafia packed half a tonne of explosives under the motorway linking Palermo with its airport, detonating it by remote control as Giovanni Falcone, an anti-mafia magistrate, drove past. The blast killed Falcone, his wife and three police officers. Weeks later, the mafia detonated a car bomb in Palermo, killing another magistrate, Paolo Borsellino.
Spatuzza, who was arrested in 1997, was speaking at a new trial connected to Borsellino's murder. He has been convicted of 40 murders, but claims to have found God while in prison, pushing him to give evidence against former fellow criminals.
