Perhaps this is an example of Brooks' observation that most bugs in software are in fact bugs in specification. I can even sorta understand the thought processes behind the specs. While there were two hull losses, there have been many, many, many more MCAS failures; the only time they resulted in holes in the ground is when the trim runaway procedures weren't followed -- that being a sort of sobering thought given that there are all sorts of other things that can lead to that happening beyond MCAS. -- Christian Kennedy, Ph.D. chris(a)mainecoon.com AF6AP | DB00000692 | PG00029419 http://www.mainecoon.com PGP KeyID 108DAB97 PGP fingerprint: 4E99 10B6 7253 B048 6685 6CBC 55E1 20A3 108D AB97 "Mr. McKittrick, after careful consideration…"
