I'm spending way too much time on this machine http://pinside.com/pinball/forum/topic/my-t2-restoration-with-pictures
So, I bought a helicopter and swat van on Ebay. I added a propeller motor and lights to the helicopter simulating as much as possible the helicopter in the movie. Then I painted and added lights to the swat van also simulating the one in the movie. Here's what I ended up with.
Here is video of it in action. I added flashers in the cockpit to simulate gunfire like in the movie. Some of the lights and propeller activate when you make the helicopter ramp shot.
