Mr G,
Another view, I went yesterday and yep it is mostly lighties with a couple of jets. After many years of attending airshows, it doesn't really impress me anymore. The rules have tightened up considerably and some of the shows are not that competent.
When Jim (RIP) Leroy was there a couple of years ago, he gave the best display I have ever seen in the Bulldog Pitts. The Saudis did a decent job with their Hawks but there were also a hell of a lot of gap fillers and lack of variety. Seen one Extra or Pitts, you have seen pretty much most and it does get repetitive. Lets face it, at a big european airshow, the Extra display is normally a chance for a quick hotdog before the heavy metal gets flying again. Even a 10 yr old boy that loves planes got bored after a couple of hours. The sideshows were pretty naff and you can't get to the flightline to see the take-offs and landings because the runway is on the other side of the site.
If you are a conessure of aerobatic lighties you will love it, if you need the sound of freedom to float your boat it will probably be a little disappoining. That said its nice to get out of DXB.
Just another opinion....
