I was surprised by 1 drone photo of crash scene. No 1/4 of a mile long debris field. This plane nosed in and buried itself. Retrieval of parts via Cat excavator and front end loader to allow sifting of dirt. I'm guessing that the software has one little unanticipated feature that only occurs when various sensor inputs and pilot inputs cause the control system to think the best course of action is to roll over and lose elevation. I'm hoping for better informed opinions of possibilities from you. If anything like that comes to light, how the hell does Boeing announce a software update?
