MJR, have you got a reference for this?
I’d like to learn how an FMC memory can be wiped by camera. I’m not saying I don’t believe you, but since a lot of flight crews take happy snaps with digital cameras, I’m surprised that this phenomena isn’t commonplace and if it’s documented, why hasn’t the information been promulgated to crews as a matter of urgency?
As to the subject of a CD player bringing down an aircraft…of course it could, all you have to do is pack it with C4.
The ignorant assumption that flight crews follow the ILS without any checks on accuracy is laughable. False glide slopes are well documented and normal flight procedures would show up a suspect glide slope at the final fix, if not sooner.
