I'm still with Bose.
Yep, the OP did post here, but if you look at posts 8 and 12, there is tendency to gripe about the treatment handed to the PPL.
Reality is that this new instructor wasn't prepared and got caught out.
He was unlucky in the sense that his faux pas was pretty much as high profile as it gets and I really sympathise with that, for many of us have got away with things that were lower profile.
However, griping at the treatment of the PPL did sound like a little like transference to me as well and I thought Bose's original comments were fair, if direct.
If this is payback time for Bose, then he does stick his head over the parapet and he's big enough to fight his own corner, but in this instance he has made astute observations.
