Siegfried activates the ejector seat which launches Ozark Annie (an obvious dummy of her) several stories high. She is in the seat all the way up, but the seat disappears on her way back down when she lands on the board.
When Max gives the gun to Ozark Annie and she fires it, the remote is in his left hand. After she kills the KAOS agent in the closet the remote is in his right hand. When he walks to the dead KOAS agent, Max's right hand is empty and the remote is in his left hand. He then walks to the sofa and picks up another remote on the sofa back in his right hand. So the remote that didn't work the invisible wall is in his left hand and the correct one in his right. He then state the one in his left hand is the for the invisible wall but that was the one that didn't work. The goes on to say that the one in his right is the TV remote but that was the one he took from the sofa which should have been the one that should have worked the invisible wall. But he uses the one in his left hand which he uses earlier that didn't work but does operate the invisible wall.
