Just think, this whole thread may have been avoided if the T6 pilot had said 'Sorry about that' over the R/T
Similar thing happended to me a few years back at Bembridge. The preceding aircraft was a touch and go who changed his mind on the runway and converted it into a landing and backtrack. I got an extra circuit in the Yak and he appologised over the radio. Job done, no one injured and no reason for me to go and duff him up (physically, verbally or in print on a forum).
I guess the OP is more concerned that the T6 pilot was either completely unaware of what was going on around him or not prepared to admit to a mistake. But I would suggest that this method of obtaining satisfaction is a bit over the top.
