Stewart Birt says in The Times "No conceivable mechanical failure nor any deficiency in onboard systems or equipment would have reproduced this accident". Perhaps he should have a word with Sqn Ldr Robert Burke, who gave evidence to the House of Lords, having had personal experience of a number of technical problems including control jams and DASH runaways, both of which could have been responsible for such an accident.
At least he has the decency to declare an interest, claiming to have been at least partially responsible for training Jon Tapper and Rick Cook, not to mention running a company with lucrative military contracts. Brown-nosing or @rse-covering? Or both? Who cares.
Nothing that he says detracts from the point that there is no evidence of negligence. Next please.
