I usually go if I can, will probably fly up.
It's not an "airshow" as such, it's serious "shop" - trade exhibitors, sales, business networking and so on. Much more a show for engineers and businessmen than pilots or spotters.
But, if you are looking to stay up to speed on what's going on in the "kit" world, it's a worthwhile trip.
and probably as last year, half a day at the show, half a day in the museum
Come to think of it, if anybody wants to cost-share up from Popham in my fastish cheap 4-seat plank, I'm open to offers - about an hour each way and should cost about £100 between us for the round trip (i.e. £25 each).
