Stunt performers are on a ship that has a magnetic device connected to it. When activated, the stunt performers’ bulletproof vests and guns are pulled from one side of the ship to the other and then back again. This was done practical. All stunt performers were attached to a wire and they were pulled with high-speed winches and pneumatic ratchets. Performers were decelerated upon impact and performers were held into place by wires to simulate the magnetic field holding them in position. Special pads were integrated into the side of the ship to help protect the performers. CGI was only used for some debris flying through the air.
