The report seems to emphasise the he was not trained in the escape manoeuvre. I would suggest that anyone with experience of turning aircraft upside down or having been in military flying knows what to do when things do not work out. As has been said before in these posts, a UP recovery is all that is needed. AH will have taught those as a JP QFI as part of instrument flying and they are tested, or were in my day, as part of the IRT. So, Wiggy, you are about correct. Roll to the nearest horizon when speed is over a certain value, and if the nose is low, apply full power.
