Murexway - whilst yours is a mature and considered view point, airline pilots do not have a monopoly on aircraft crash investigations. A whole range of skills are involved. Even when there is no evidence, brain storming often helps those concerned to think of something that never occurred to them. A necessary element of brain storming is not to criticise contributions. Of course on an open forum like this you will get teenagers coming in and making silly comments. Those are easy to spot, even for journalists. The problem with some journalists is that they lack ethics and will print anything but that should not discourage debate.
