Where would you land on a jumping jet that is moving at 600 km/hr?

When you're inside a plane that is moving at a speed of 600 km/hr, and you jump straight up INSIDE the plane. Where will you land? My science teacher gave this question to the class and she said the answer is you will land at the same place you jumped from. She then explained that you're moving with the plane. I don't get it. When you jumped, your feet don't touch the floor of the plane. When you land down, aren't you suppose to be at a different place from where you started? Please can somebody explain to me? Thanks.

Could there really have been a large planet between Mars &Jupiter in the past: why the asteroid belt is there?

I've heard about the possibility that it was destroyed within the last 10-20,000 years and could even be responcible for Saturn's ring of ice. Plus it caused great destruction on Earth... It could be interpreted that way from many ancient religious texts too..
