I had wondered about a pitot issue given the IAS problems reported, and wondered at the chances of additional hardware failure w AoA vane tripping MCAS....
...but does this show that IAS Disagree can in fact be caused by the AoA failure?

So instead of pitot issue AND AoA issue we are back to all being caused by a bad alpha vane?
