Purely as a matter of interest; I flew into Duxford in my little aeroplane some years ago. I think I was the only aeroplane on the frequency. On finals I was told to land on 24 Grass because the main runway was closed.
So, with my reasonable experience of aviation, I side-stepped to 24 Grass and landed.
Several hours later, I departed from Duxford. I was cleared to taxi to 24 (which I assumed meant the same 24 Grass that I landed upon). I held short of where I assumed the holding point to the grass runway was to be BERATED by the pillock on the other end of the radio telling me to get my arse down to the end of runway 24 (tarmac).
I felt like telling him that I had 17,000 hours of operating large aircraft into airfields such as JFK, ORD and ATL but I bit my tongue and apologised.
I have never ever flown back into Duxford's precious airspace nor shall I ever again.
