This raises a question I was saving for next month when we're out of 
character sketches and chapter summaries, but what the heck, it's come 
up so I'll ask it now.  Maybe I should ask JKR.  I also want to ask 
her to finish Dumbledore's joke from GF ch 12.  *What* happens when a 
troll, a hag, and a leprechaun go into a bar together?  But back to 
the third task:

What do the onlookers see during the 3rd Task?  Can they see down into 
the maze?  If so, don't they see Krum attacking Cedric (and possibly 
Moody attacking Fleur, blasting various obstacles out of Harry's way, 
etc.)?  Or can they not see anything?  (Like the 2nd Task, it doesn't 
seem like a very interesting spectator event in that case...)

  Harry thought this was going a bit far.
