[SystemSafety] [EXT] Re: "FAA chief '100% confident' of 737 MAX safety as flights to resume"

[Steve Tockey]

For what it¹s worth, I¹m going to chalk this one up to marketing.

The esteemed members of this group are all fully aware of the
impossibility of the FAA chief¹s claim. On the other hand, the vast
majority of the general population can¹t think in these terms. If anyone
in that kind of position says anything that hints at the slightest
doubt‹even when it is ridiculously low risk‹it would cause a public
outcry. Just imagine it, the FAA chief says,

³The 737 MAX is as safe as we can make it² (read that to mean, ³it is no
less safe than any other commercial airliner²)

The press would have a field day:

³FAA Chief says 737 MAX is less than 100% safe! Therefor it MUST be
dangerous‹as dangerous as it was before!!!²


I¹m pretty sure the FAA chief fully understands the need for less than
100% confidence, it was said that way to placate the general public who
clearly don¹t know any better. Seriously, how many adults continue to
believe the earth is flat . . .

So it goes on. 
These guys worry me.
I wonder if any of them has ever written a line of code.
Do any of them understand how easily a misplaced colon can bring down a
system ... and the 
aircraft it embeds.
When will they understand that the only way to certify a complex system is
to have skilled 
professionals embedded in its development from start to finish.
Professionals who¹s only love is
for the technology . Professionals unimbued with the idolatry  of
shareholder value.

Until that time I take solace in stoic philosophy.
Πall men are made one for another: either then teach them better or bear
with them.¹

Perhaps the recent Notices (directives to the FAA personnel) tell a more
complete the story.
