I hope DFC doesn't work for the CAA, otherwise we are all doomed.....
As regards that Boeing that came down after ground maint. taped over the static vents, what happened there beggars belief and IMHO can be explained only by a near total lack of systems knowledge (below PPL level) on the part of the 3rd world crew. What does that tell us? I suppose it tells us that you can fly an airliner, on a regular airliner route, while knowing bugger all about the basics. Irrelevant in this context.
