Not wanting to get into a slanging match, but who decides when conditions are favourable?
Sherburn is A/G and an Aircraft en route to Sherburn doesn't know the traffic conditions.
I would be a seriously annoyed if some bleeder called long final if I was late downwind or on base leg.
At a training airfield like Sherburn conforming to the circuit as either published in a flight guide or on the radio has to be better than a pilot deciding his own join.
