I admit that after a couple of years observation of these threads I value the comments and discussions here more than reading the actual reports and I haven't read today's release. We have a fair knowledge of what the crew did. They did what they did because it relected their appreciation of the situation and following that, their apparently appropriate response. The important thing is surely to understand why they didn't understand the true dynamic state of the aircraft. Without that knowledge nothing that follows is likely to ever be of any use. The upshot is surely that they didn't realise they were stalled. Your question to the technologists is surely how could you design a system that would let that happen ?
