Giovanni Brusca was tasked with killing Falcone. Riina wanted the murder carried out in Sicily in a demonstration of Mafia power; he instructed that the attack should be on Highway A29, which Falcone had to use to get from the airport to his home on his weekly visits. 400 kilograms (881 lbs.) of explosives were placed in a culvert under the highway between Palermo International Airport and the city of Palermo, near the town of Capaci. Brusca's men carried out test drives, using flashbulbs to simulate detonating the blast on a speeding car, and a concrete structure was specially created and destroyed in an experimental explosion to see if the bomb would be powerful enough. Leoluca Bagarella assisted at the scene during preparations.
