It says more about the limitations of us as humans than anything else.

I do agree that you need two people though, and yes, more does not equate to
more security, it tends to just add complexity.

Welcome to the post-CAIB "need more government inspectors" world.


...Jorge, this might be the one time I've ever disagreed with you, but
I'd rather see more inspectors actually doing the job properly than
something go wrong because a step was missed.


On the other hand, we *did* have that issue last mission where the
White Room had a panel that wasn't lashed down properly prior to arm
swingback, and there were several inspectors then as well...


And there you have it. Are additional inspectors useful or are they not?
Your gut says "yes" but your data says "no." That squares very well with
my experience as well. We had some products that required four signatures,
but in all my years I never saw anybody past the second ever catch a
technical error, just editorial suggestions.


A "second set of eyes" is a good thing in general, both in the cockpit and
on the ground. But the added value of additional sets of eyes beyond the
second asymptotically (and rapidly) approaches zero. That is because
adding signatures divides accountability.

morons will soon have programmers capable of being morons only." That

Well one person having a off day can easily miss something

Two people make it less likely, but 2 people can still have a off day.

Hopefully 3 people dont ALL have a brain freeze.

But when it comes to the hatch its likely a great idea.........

hey nasa cut the number of workers from 3 to 2.

3 flights later the orbiter depressurized on launch

not a worthwhile risk!
