I was there Tuesday and Friday.
I agree with Gaunty, and others, the trade display was awesome and there were some very serious heavy hitters from the U.S. and elsewhere talking to numerous defence types from all over Asia.
I liked the Cirrus stand, especially when it rained on Tuesday. The diesels looked good, and no sign of any competitive response from Continental or Lycoming.
The flying display was a little disappointing. All the old favourites were there, but nothing except for some magic acrobatics!!
I left early on Friday, but heard from others that the night show was a disappointmen. The delays were apparently caused by a Jetstar Arrival and Departure that didn't exactly thrill the crowd.
