Now hang on Bez, I think you're dismissing this a little too quickly, we could have a plane on a conveyer belt situation here.
How fast will the lift being going when it hits the deck? Lets say, since it's falling in a reasonably air tight tunnel, it has quite a low terminal velocity, say 50mph?
Now all you have to do, in your responsibility as a lift manufacturer, is put a little window in the lift and a red mark on the wall near the bottom so people can see when they have to jump. As long as they jump upwards at 50mph or more, they're sorted.
