Will Smith is driving a motorcycle in a car chase when he jumps to the back of a tractor trailer, runs towards the cab, and jumps to grab hold of a ladder hanging from a helicopter. The stuntman running up the semi to the hanging ladder was done practically with a ladder hanging from a crane arm and a helicopter hovering to the side for prop wash only. The stuntman was on a stunt rigging slack removal system that allowed him to start at the back of the semi, run toward the ladder, and jump as fireballs were exploding behind him. The shot of the stunt double rigged to the ladder and helicopter was overlapped with another explosion to tie together shots of the helicopter and fireballs. The helicopter flying away with the stunt double on the ladder was done practically.
