I haven't been to Farnborough for a while now. On the last 2 occasions I had to queue up for some security check - first time I'd ever seen that at an air show. Last time the grass was so wet that everyone advised that the car parks were seas of mud, so to go by train as there was a free bus to the show from the station. So that's what I did - except that when queuing to come out there was no bus shelter of any kind and everyone got soaked - very poor organisation.
As for the show itself, the pavilions were virtually empty (this wasn't on a 'public' day) with people manning the stands hanging around looking bored. A few aircraft flew, but nothing very impressive.
Expensive too. But the fat cats in the chalets were no doubt wooed by the bigger manufacturers as ever....
