I do need to make a correction though, still irrelevant, but might as well get it right.  I mixed up a few things up with a 767 it seems:

Vmo (Velocity max operating) for a 737 is 340 knots IAS.
Mmo (Mach max operating) for a 737 is .82, which is 279 knots IAS @ 35,000 feet.

Vmo is the same as Vne.

Perhaps someone can chime in here on this bit, but I'm wondering if perhaps the Mmo exists because of something called "mach tuck."  So maybe I'm confusing "Vne" changing with altitude, with "Vne" adjusting to Mach limitations of the wing...

Bah, this aerodynamics stuff has a couple variables... :confused:

I subscribe to the theory that airplanes fly because of gypsy magic.

If your interested in that stuff I have some official documents from Boeing on that topic for 757 & 767, I can email them to you.

No problem.

Since it's kinda a lot I recommend you use "ctrl f" to find the "Vmo" section.
