This forum is titled "Spotters corner" and is the forum to which posters are directed by the managers if you do not belong to the privileged classes:
If you're not a professional pilot but want to discuss issues about the job, this is the best place to loiter. You won't be moved on by 'security' and there'll be plenty of experts to answer any questions.
If the poster was intrigued, puzzled, baffled etc and wondered about a certain aspect of the airline/aircraft/airport operation, this would indeed be the appropriate place to post his/her query.
There is, in my view, no need to belittle the poster for asking something that may be blindingly obvious to the over qualified experts. Remember, once you too knew sod all! (And probably asked the same sort of question).
