miles offtarget,
(a) let's not delete the thread - the question is quite valid and should remain.
(b) you need to expect the (more experienced) airline pilot fraternity to be critical - nature of the business. No different to academic peer review in principle .. but tends to be a tad more in your face, as it were - again nature of the business - flying can't afford to be too PC due to the occasional risk of dying during the PC bit. The older folk tend to understand that from near bitter experience.
Come to think of it, I have seen the occasional academic review which was far more acid than this thread's commentary ...
