First, you hear the sound of an approaching helicopter. Then you feel a breeze (supposedly from the rotors, but there are hidden fans somewhere in the house). Then you see a projection of the helicopter flying in and turning to face the audience, with bright headlights in our eyes, then a panel slides away, revealing the three-dimensional helicopter, which is on a platform that extends and rotates. After everyone piles in (or runs through), the platform lifts and turns the thing back to position one and the panel slides back in front of it. Strangely, there is no projection of the thing flying away.
