The different sky and enhanced lights make a big difference. Now there's more than one color in that scene! (which I said about a scene in AOTC the other day, too)
Oh, and vaderios, in that pic I made, they're not 'remains' of a plane, it is a plane. ;) It's the opening to the movie "Airplane!" They made it a spoof of "Jaws", where all you see is that bit of the plane going through the clouds like Jaws' fin went through the water.
