Interesting that at no point during the congressional hearings did anyone ask how come the AoA indication failed on both crashed planes.
I am just an engineer with a PhD, not a pilot, and so for me the origin of a malfunction is significant. Safety doesn't start when someone puts his ass on the seat in the pointy end. And as a computer geek I do suspect that the AoA indicator issue is entirely spurious, a software artefact. In a similar occurrence, QF72, the AoA issues were entirely a software problem.
I suspect this sudden silence on an important topic is because a failed sensor is not a liability issue, while a bug is squarely in Boeing's wheelhouse.
