I remember being on the flightline one day, pretty sure it was 83/84 and 1 727 took the crew down to pick up the other 727 after c check. They must have done a task on the way down. anyway, both left at same time and empty and when chatting with the eng, his words were "that was crazy", so they must have had some fun racing home.

Vmo = Max Operating Speed (an Indicated Airspeed) Mmo = Max Operating Mach Number Basically as fast as you're allowed to go. Vmo/Mmo is depicted on Boeing aircraft Primary Flight Displays as a series of red squares at the top of the airspeed scale (sometimes called "the red army"), where the bottom square is either Vmo or Mmo depending on altitude, or the flap limit speed when flap is extended. In most auto flight modes, the aircraft will pitch up or reduce thrust and will not allow the aircraft to exceed this speed, even though the speed bug is set higher than the limit. On the 777 the flight control computers (in normal mode) will also intervene to pitch up to stop an overspeed if Vmo/Mmo is exceeded. Pic here: www.airliners.net/photo/247457/L/

Velocity-Maximum Operating.
We used to run the 727 onto CHC runway 20 at 360 kts to Woodend NDB at 2000ft, and with a 10 kt headwind, idle, speedbrake, descend, swapping gear for speedbrake (couldn't have speedbrake and flap), flaps at limiting speed and be spoiled-up, stable at 600ft.
