I am assuming that this was on the grounds that the Extra team have some sort of general permit to do aeros at their home airfield anyway - and this was 'out of PFA ours' - ie when the airfield had officially reverted back to the usual FISO service, and was not therefore still under the special CAA rally rules and regs.
The 'event' actually occurred at a time that the TRA was still active according to the AIC.
My only problem with it was what if a non-radio aircraft was landing into sun on the grass totally in accordance with the AIC only to find a low level Extra coming the opposite way down the runway.....
