Jones was somewhat of a pugilist at the time of Vaughan's earlier stoush, I'd have thought he'd have been aware of that back then....
... as for this time round, it seems a fair leap to what he's saying, if there's no evidence. Equally it could have been a flying pig he ran into
I should think a drone, if that was the reason, would have left some alien plastic around, or some identifiable witness marks? The pig would have just enjoyed the scratch and carried on its way...
