Mark,

I'm not so sure that the "ground" people really are aware or well trained enough to know that.  :o

It would hardly ever come up in their normal day to day operation. In the old days, only mechanics would move aircraft. But mechanics cost more than ramp folks, so airlines switched to rampies to do the tasks that mechanics used to do. For the most part there is no problem, but in this case it really showed how complicated modern planes are and how important good training is to the operation.
