I went today (Friday).
It was full of casual people, and loads of kids on school trips.
The indoor stuff, which I did 100%, was OK but basically same as every other time. Aerospace companies, and aerospace component/material suppliers. Interesting to an "engineer"
The outdoor stuff was much thinner than on previous shows. Very few aircraft on the ground to look at.
I am not into air displays but saw the A380 - an ugly monster which "anybody" could have built if they were given a brief to build a bigger jumbo than anybody else had done before. It was doing impressive slow speed flying, made possible not by pilot skills but by the computer holding it right on the very edge of the stall and the pilot only needs to pull the stick all the way back
The car parks were far away, with free buses laid on. This worked well, but only because the crowds were thin. Catering was good too.
Lots of black limos driving VIPs round the place
