Agreed. I try and pose questions to increase my understanding, rather than profer unwanted opinions outside my knowledge and experience (although I have a bit of that having many years experience building airports and the past 40 flying various small flying machines).
I am a regular flyer between Qatar and mid west USA and points in between but I have never posed as a Big Jet Driver and my profile is clear. (I don't care if I have a flag that says Aviation Industry Professional but not qualified on big jets).
Why then is it so easy to get flamed ? (dons hard hat again !)
