I got this email back from E Kirkby re August 6th. I'm afraid I won't be laying out £52 in the hope that the weather plays ball.-
You would need to buy tickets in advance I'm afraid, they are £13.00 adults.
The landing fee is £10.00 per aircraft.
I will also need the details of your aircraft and the expected time of
arrival.
Kind Regards,
