It might be fun to have the Executor hidden in a huge cloud bank and suddenly break through the clouds as the Falcon escapes, like the Ajax (or was it the Warlock?) in Flash Gordon only not crap.
Before the PT I wouldn't have thought a ship that size would be capable of atmospheric flight but now I guess it could.
It would have a lot more impact than Leia pointing at a dart in the distance but it would have to be one hell of a big cloud to hide something that big.
