"Would it be possible - the next time there is a tragic accident / incident that there are two crash threads - one for pilots / engineers and the qualified to post on - the other clearly labelled for irrelevant drivel?"

You're right though, the thread has become largely irrelevant. There has not been any useful/factual information posted in here for days.
