The Qantas Flight 72 incident was quite a bit different, as all AoA sensors were working correctly. The issue was due to corruption on one of the CPU exploiting these AoA sensors value [1]. Though you are entirely correct that there was a design flaw and the incident should not have happened, since these corrupted values ended up overriding the correctly calculated ones from the other ADIRU units. [1] "The exact nature of the corruption was that the ADIRU CPU erroneously re-labelled the altitude data word so that the binary data that represented 37,012 (the altitude at the time of the incident) would represent an angle of attack of 50.625 degrees." https://en.wikipedia.org/wiki/Qantas_Flight_72#Potential_trigger_types https://en.wikipedia.org/wiki/Qantas_Flight_72#Potential_tri...
