I'm curious about how Atlantis could actually fly and manouvere.
Look at this (although I think it's the Asurans ship it's the same design and principle):
It clearly has those bad boy engines underneath each pier supporting arm and we all know that Atlantis flys upwards when taking off and also when flying through space / hyperspace.
In the episode where Atlantis leaves Lantia (I think thats the planets name lol) Atlantis drops out of hyperspace and then continues moving sideways. This indicates that it has somehow turned itself somehow.
Now we only see the engine outlets under the piers. We don't see any other sorts of thrusters anywhere and yet Atlantis is able to manouvere itself round 180 degrees in orbit after exiting hyperspace in order to land on a new planet. Additionally it would also need some sort of upwards firing thursters to act as brakes yet we never see this either.
On one pier we see what look like super huge rudders like you'd find on a boat or plane but in space those would be useless (especially when flying upwards lol).
So.. just how did Atlantis perform it's manouveres?
