Remember people (CamelhAir and hobie particularly), there is no such thing as a stupid question. However, there is such a thing as an immature, ignorant, and downright abusive response.
Everybody has the right to ask questions here, not just the small elite of airline pilots. Until this forum becomes 'Airline Pilots Only', then kindly allow people to pose legitimate questions without interference or undue hostility.
If you don't like the question, then don't answer it, its as simple as that. Leave somebody else to give a constructive answer, instead of wasting space with your infantile verbal diahorrea.
Cabot, you're well within your rights to ask such a question. Pay no attention to those Ppruners who wish to spend their time putting other 'lesser mortals' down.
