Flight Speed?

Recommended Posts

http://www.boeing.com/commercial/747family/background.html

The website lists it as Mach .855

The 747-400 incorporates major aerodynamic improvements over earlier 747 models, including the addition of winglets to reduce drag, new avionics, a new flight deck and the latest in-flight entertainment systems. And, the 747 continues to be the world's fastest subsonic jetliner, cruising at Mach .855 -- or 85.5 percent of the speed of sound.

Which at sea level in perfect conditions, and measuring airspeed - not ground speed -

That would effectively be : 649.8

Sorry - I'm not putting a tuning fork anywhere near my graduated cylinder.

All the bubbles would come out and my beer would go flat.
