Just read QTA.

I always assumed in PS/SS chapter 2 (when Harry's thinking about the 
strange things that have happened) that Harry had taken "a magical 
flying leap" or some such to end up on the roof of the school.  
According to QTA, though, wizards can't just "fly" so now I'm revising 
my assumption.  Did Harry apparate to the top of the chimney?  If so, 
why?  If he was trying to get behind the big trash cans, why isn't that 
where he apparated to?  Assuming that he did apparate and doesn't have 
some power that other wizards don't have.
