So here is what happens with VNO. People like acronyms. So those who
were taught that VNO is Normal operation speed needed words that
matched VNO. For those of us who are anal retentive and yes I am one
of those people because I must follow strict interpretation of
regulations because I am required to do so, we'll always know that
VNO is Maximum structural cruising speed. Look in FAR part 1 under
definitions.

So... your response to Jose's riddle is that "it's VNO because they called
it VNO"?

I would think that the "anal retentive" response would actually supply an
answer to how that acronym was derived, since that was the question that
was asked. We all know that we just have to memorize those things that
make no logical sense. ;-)
