On 15 April 1999, Felix Baumgartner set the world record for BASE jumping (since broken) by jumping off a window cleaning crane on the Petronas Towers.[19][20]
Thousands of people were evacuated on 12 September 2001 after a bomb threat was phoned the day after the September 11 attacks destroyed the World Trade Center towers in New York City. Bomb Disposal squads found no bomb in the Petronas towers but they evacuated everyone. Workers and shoppers were allowed to return three hours later, around noon. No one was hurt during the evacuation.[21]
