Was lucky enough to catch the A380 display (by accident ... it's a long story!) from the train station platform at Schoenefeld last June (2008) - big, very low, and sooooo slow on banked turns that it just seems to hang in the air!
Here's a interesting thought tho' - the train platforms are about 1 mile from the runways at Schoenefeld (GoogleEarth), and the A380 was banking overhead and way on out past the station as it turned back to the airport ......... the bay at West Strand is about 3/4 of a mile wide, so there could be some really amazing photo opportunities to be had from Ramore Head, regardless of the weather, on the day!
