'Would folks without experience please not contribute? Their questions are not valid.'
As an earlier contributor to this thread I regretably I am one of those without 'experience', I may stand corrected but I felt that I made a positive contribution. Your post is indeed interesting and raises many 'questions', indeed I would challenge some of your assertions. My point is that open debate/discussion is healthy, however, while agreeing that some contributors have little to add, it also appears at times that a small minority of the flight deck fraternity contributing to this forum have exclusive rights to 'opinions'. Now.....back to the original thread, and the opinion of others.
