Out of interest, before the grounding were there any recorded instances of a more benign air data failure on a MAX, obviously without producing the JT/ET result ?
ET they have in many comments assumed a AoA failure due "most likely" a bird strike.
But no parts found on/near runway.
So how about a possible internal of aircraft AOA failure - Probe? Computer? Connector? Code?
