The RAF Typhoon's not got a display auth yet so it couldn't actually do a full air display at Cosford, which is why it only did a couple of flypasts. Disappointing I know but that was unfortunately the best it was allowed to do. Furthermore it's only appearing at 5 displays this year! As for more Airforce kit in the lineup, what more did you want??? With the exception of GR4 we had every front line fighter aircraft the RAF fly, as well as the first Chinook display in 10 years!
Any issues of static displays, well just think about it; what can land/depart at Cosford? Besides, there were scores of static aircraft in situ at the RAF museum, any more and Joe Public would most likely have found him/herself rather bored.
In my view, the day went as well as can be expected. Sympathies to all those stuck in the nightmarish traffic though, but 18,000 cars down Neachly Lane? Not a lot Cosford could do about that either.
Counter-rant over.
