Just a general observation that the ground investigation effort seems a little less than professional: the investigators have driven rather casually all over the debris field - note the wheel tracks across that long cable attached to the tail section, for instance - and when I see that, I wonder what other poor handling the wreckage has undergone that we haven't seen.
Then too, there's a thundering herd of men in suits and ties in the photos. It's never good for productivity to have the big bosses on the factory floor.
Well, maybe I'm just being a worrier.
