Along with a couple of ex-RAF mates, I attended on the Saturday.
All of us thought it to be overpriced, given the poor content of both the flying and static displays. The latter had virtually no 'labelling', and there was a dearth of operators on hand to chat with.
We paid for admittance to the Lincoln enclosure which was also disappointing. Very limited table seating, and the quality of the buffet left much to be desired.
On the plus side, access and departure was well organised; and the attitude of the volunteers was commendable.
Hope RIAT 2018 comes up trumps.
