Excuse me but when did the airfield become a part of the hunt site?
The man drove cross country to beard the pilot at his aircraft did he not?
That has been reported. I can say though that there is another story - which I heard from a colleague who was a personal friend of the victim - that he had in fact driven to Long Marston to film the pilot in order to get evidence of identity, as they were aware of who owned the ac but not who was flying it. According to that version, the film was made by a hunt supporter, therefore.
I offer that purely because things are being discussed as 'fact' - as above - when in fact they are opinion.
