"Yet here, on a forum frequented by people who supposedly have a passion for aviation, I see posts taking delight in criticising Australia's premier aviation event and complain about having to share it with Joe public."
Do they have to share with "Joe public" ?
Web site says "Trade Exhibition" and then "Public Airshow"
with a one day overlap on the 1st and the public only allowed
in after 2.00pm.
Seems pretty clear to me that the whole event is in two parts,
professionals and public.
