Some of the recent programming "paradigms" I've been catching up on is pair programming and mob programming, where there's always more than one person reading, and often contributing to, every line of code. One claim (due to different people having different areas of knowledge, and thus one sees problems another doesn't) is this substantially lowers the number of bugs.

I can think of at least one traditional idea that goes against this, especially where security is involved, that only people with a "need to know" see the design.

I would hope need to know never applied to safety critical systems, which an airplane certainly qualifies as.

Later at that same company, I moved into product development and the boss insisted on peer reviews. So we put our circuit on the table and about 10 guys ripped it to shreds. You quickly learned to have only components that were really needed and to have calculated everything. Later, the reviews became much more structured so we had safety, reliability, manufacturability, testability, cost etc. A full review before 1st pre- production prototyping was a a 3 or 4 hour process - and people came prepared.

When I went across to semis in ‘96, I got introduced to the FMEA and 8D processes . . . ‘nother whole set of disciplines.
 
There was an possibility to cancel immediately by the pilots the action that led to the crash. It was done on a similar flight the day before, on the same plane of the 2nd crash, by a 3rd pilot hitching a ride in the cockpit.

Was it not a case of serendipity that the 3rd pilot was even present and knew about that option?
“OK, so why weren’t we trained on that ‘feature’?”
 
Didn't we do this one to death 25 odd pages ago? Doesn't seem any point in bringing it back up.

Do you still not realize that this forum is like that?
there is no thread tracking and consequently they can all happen again.

That topic has been suggested by the members and debated by the mods and they agreed that it was impossible for the task of constantly reviewing all the contents, grouping them, etc., etc.

You have to be less talkative and inform yourself more.

Or simply, if you don't have anything important to say, don't think please
