Earth to Jose... HELLLOOO... those individuals get special training and
are licensed to perform aircraft surface movement operations within the
constraints of their job functions, and within limited areas. I doubt
they have a blanket authorization to taxi an airplane out to a runway.

We are NOT talking about THOSe sorts of indivisuals we are talking about
a student with just a few hours of training, supposedly asked to "go taxi
an airplane around" for the purposes of learning how to do it.

Sheesh...
