Did it cross your mind that it could be a combination of them? Drop the accusatory tone when you don't understand the content. Do you not see the irony in writing an accusatory reply to me? ;-) To your main point, I understand the content; I do, however, resent people boldly stating "that can't happen, it's too unlikely," only to then say "Oh, right, yeah, if you exclude old planes, domestic flights and blah blah blah blah blah." I do concede that it would be more helpful if I was less of an arse about it though.
