A system they weren't told about, weren't trained on. What they have is an "AOA disagree" indicator, among dozens of indicators. There's no reason for them to see it or go looking for it in the example cases of MCAS upset where they're reacting to an urgent situation. The indicator might be useful for a maintenance squawk report. Ordinarily sensor disagree would give you some idea what could be affected because you've had training to tell you this. Not in the MCAS upset due to faulty AOA sensor case. Until the reports are complete, I think it's getting out over one's skis to say would would have been obvious to U.S. pilots.
