My God... As klintE says, "this is unbelievable".
I am familiar with "officials" in Egypt but even so, the level of ignorance -- and the level of insensitivity -- of some of these "officials" is disgusting. And not just this supposed "forensic official" who -- as klintE suggests -- is obviously inexperienced in the art and science of aircraft accident investigations (re high energy impacts) but others as well over the past few days.
From the "Head of ANS", to the "Military official in charge" to the Egyptian president himself, statements have been ill informed, premature, and downright stupid. The Egyptian authorities are lacking in a lot of areas; one critical one is a need for some serious training in media / public communications -- and cultural awareness.
It's beyond embarrassing -- but they don't even realize that.
