You mean Bruce; there was no Ron you quoted. Just Bruce's post, and what
he plucked from Brian's. But that means you read Bruce's reply, but you
didn't read Brian's post which Bruce conveniently snipped, eliding
Brian's comment about backups? Yeah, that's a problem dropping into a
thread midway, especially when the heart's been snipped out of it. You
ought to go back and read Brian's initial post that started all this
then, dontcha tink? Or did you indeed see his statements about the
backup IGN and fueling?

Presumption has no excuse, regardless of where you work The person
replied to by Bruce stated plainly he had backups in his design. So no,
taking him to task for potentially inappropriately using an auto ECU
wasn't "worth mentioning again". It wasn't even worth mentioning the
first time.

Not so easy. Your note was in error, in that you apparently didn't know
the context in which you replied. You replied to a thread, not a single
post, but an ongoing discussion.

>I'm a dumb limey. Who is Yogi Berra?

One of America's premier 20th century philosophers, who just happened to
also play Catcher with the New York Yankees for spending money. Here's
another one of his astute observations that seems so timely just now, if
only some would observe it:

	"If you ask me anything I don't know, I'm not going to answer."

Corollary: if the above is considered wise, then surely, "If there's
something you don't know, don't go preaching it to everybody on the
loudspeaker". :)

Questions work even better, when you have something to learn. Too bad
that lesson is lost sometimes. Good to see not on you, Bill. :-;

Even the primitive mechanical FI first used in aviation has alot of
interesting and informative wrinkles that you won't find anywhere else,
including in early automotive mechanical FI. It's different not just
because for aviation, but because different minds in different
industries worked on similar problems, and so came up with interesting
contrasts in their solutions. Lots to observe just by watching.
