As an air show line-up, it is poor yes, but having met with the organisers a couple of weeks back, it became clear that they've put maximum effort in and achieved all they can in the time they've had, for that they deserve full credit
If I was to pick fault, I would suggest they should have spent 16 months planning a 2016 event rather than four months rushing a 2015 one, or at the very least called it an Open Day or something other than an Air Show.
There are still more aircraft to be announced yet, and they've already started planning next years event which should be a belter as they should get RAF and other military assets etc.
This year was always a case of let's crawl before we walk, but no doubt there will be plenty of backlash.
