Angle of Attack

Cover of the book "Flying Beyond the Stall"I've been reading Flying Beyond the Stall: The X-31 and the Advent of Supermaneuverability by Douglas A. Joyce. Very quickly what struck me was that the issue that caused the X-31 to crash in 1995 was incorrect Angle of Attack (AoA) sensor data causing the software to override the pilot and crash the plane. Which was the same thing that happened to the Boeing 737 Max planes that crashed.

Maybe it is because I'm getting older but I'm getting more and more concerned about how the Tech industry forces older engineers out and tries to replace them with entry-level programmers. This isn't an natural issue of passing the baton. This is an issue of trying to replace highly skilled and experienced people with minimally skilled and no experience people.

So many of the software issues that we fight today have already been solved. If we just take the time to learn from the past then we could avoid repeating these mistakes.
