Wow, that second video... WOW.
A few things...
1: Holy crap, the fan blades turn in the A380.
2: The people inside the terminal aren't moving. Very realistic.

3: There are times during the night action where you're hard pressed to tell that it's not the real thing.
4: These guys really stomp on the brakes at the gates. ???
5: I'd like to see the mechanical workings. It seems like the complexity must be mind bending.
6: There's a maintenance hangar!
7: Can you imagine having to dust that thing?
