I find it rather sad that some posters on this forum are so full of vitriol and bile that they feel an overwhelming urge to have a go at anybody who asks an innocent question on here
Kelvin - I don't see any vitriol or bile in the comments made with this post. What I see is aviation folk (I include myself in this) being sarcastic, witty and humorous in their remarks based on years of experience in the aviation field. If you want vitriol and bile look in the Middle East forum and there is plenty to choose from there.
As stated the OP possibly answered his own question, however there will always those that want to 'chip in' in some shape or form. That's aviation for you.
