There was no warning of the uncommanded slat retraction on the left side and no subsequent stick shaker activation. Had the nose been lowered in reaction to a stall warning, the aircraft could have been saved based on numerous simulator tests. As it was, the FO was the flying pilot on AA 191 and otherwise flew a by the book V1 cut. Stick shakers on both sides were mandated afterwards. It wouldn’t surprise me if a single engineer that worked on MCAS was even old enough to have ever heard of AA 191.
