Myth:

It is impossible to perform a barrel roll such that the pilot feels
exactly 1 gee of force perpendicular to the floor of the cockpit.

No maneuver that involves a change in altitude can maintain exactly 1
G along the net acceleration vector (including perpendicular to the
cockpit floor). This is not a myth, it's a fact.

Do you see the word "acceleration" anywhere in my "myth" statement? I have
no idea what it is you think you are trying to say, but it has nothing to
do with the myth I am attempting to debunk.

You appear to be confusing acceleration and force (you appear at times to
treat them as the same thing), among other faults in your thinking. If
taken literally, all your statements regarding the physics of the situation
are incorrect.
