If this has been posted before, tell me. Why is it that when large ships enter the atmosphere of a planet in all of the stargate they show significant burn up on their shields (if active), and yet you don't see this with the Puddle jumpers? It can't be because it's too small because anything on atmospheric entry has burn up. It's why the shuttle is black on the bottom, it has heat tiles to protect it. So why don't you see it with Puddle Jumpers?
