The doomed Ethiopian Airlines Boeing 737 Max that crashed and killed 157 people last month reportedly had its angle-of-attack sensor damaged on takeoff from a foreign object or bird.
The damaged sensor went on to trigger inaccurate data and resulted in the pilots turning the anti-stall software - known as MCAS - off, but it re-engaged and pushed the jet downwards, sources told ABC News.

Little later in article it says software cannot reactivate by itself, needs to be manually turned on. Dont know if this gives Boeing an out on pilot error grounds or just plain bad luck.
