I went Sunday and have similar comments to PS2 but that being said it was still pretty good and pretty much all re-occurring Airshows suffer from the same repeatedness. Not sure how many were there but it seemed like a couple of hundred thousand and it was *very* busy.
A few Jetstar arrivals and departures broke it up a little and it was good to see the Q747 takoff in the middle of the show being so close to it on the crowd line. I was a little disappointed that it didn't come back for a high speed fly-by.
That mediaum Italian freighter military thing was the most impressive thing I've seen for a while. A bit smaller than a Herc, Herc looking with 2 engines and it was doing barrel rolls and wingovers - quite impressive!
