How about continuously pressing the little red button on the stick and pushing?
Would the cutie in the jumpseat be able to:
a) stop the jockey doing it?
b) jump up against the negative 1g and open the door for the other jockey who was surprised with his pants down in the loo?
or, as we are at it, even in a normal scenario:
a) would the jockey in the other seat be able to react if, by courtesy of Airbus, his stick is pressed dead?
b) would he be able to disconnect the computers and, with his willie-stickie working again, be able to counteract the algebraic sum of "full down" and "full up" to stop the imminent impact?
c) would a quarter-pounded jockey be able to counteract a sumo-fighting trained colleague who pushes the yoke in an interconnected tractor cockpit?
There is unfortunately little that all the knee jerk reactions of the powers can do if there is a real malicious intent by a pilot, in any machine.
It's only to please the public and to continue with minimal cost involved.
