Personally, I thought it was really good, except for the nightmare that was getting out of the parking lot. The displays were good (Never heard of "The Blades", but v. impressive) - Vulcan was just awesome and the A380, that was excellent. And, (it pains me to say('cos I'm jealous)) the Reds were nice, friendly blokes who gave a good display to round it off.
Lots of gizzits for the kids, things to participate in, interactive - all in all, better than RIAT (this year) and, for a trade show with a public bent, I liked it. (Free tickets helped).
