The airplane is op specs limited to +2.5 g's and -1.0g. Not worried
about stalling a 747. There's so much mass the tow rope would break
before any instant degradation would show up on the airspeed
indicator. Airspeed trends take A LONG LONG time to develop on this
bird. It's not like anything you've every flown before. I use the
analogy of surfing on a mountain of metal to describe a visual
approach on the 74 because the previous vector it was on before you
made the change [control input] is what it will be on for a number of
seconds. By the
time you've pulled off the thrusters because you're too fast, the huge
inertia will keep it accelerating.

Inertia: a property of matter whereby it remains at rest or continues
in uniform motion unless acted upon by some outside force.

The uniform motion in my example was acceleration. In this bird it

Acceleration is not uniform motion.

takes longer for the opposing force: drag to arrest the motion. Due
to it's large Kinetic Energy. Can you be more specific? What part do
you disagree with?

That an object will keep accelerating in the absence of an external
force on the object. Inertia will keep it moving at a constant velocity,
but it won't keep it accelerating.
