1. Because he said this debate "wasn't done". I think it is clearly done -- no more new stuff to be said. Both sides have said all that they want to say.
It isn't 'done' because 'well I still think it looks weird' is not a reasonable conclusion to the type of debate you claim to want to have. Let me put this very simply:
-You suggest the movement of the steerable S-band antenna is evidence of gravity.
-You are presented with evidence that the mechanism is capable of generating such movements, and in fact is known and documented to have produced similar ones on every mission.
-Since it is clearly possible for the antenna to behave in that manner in space, the movement can no longer be considered evidence of gravity.
-Additionally, but not so significantly once the movement can be explained by existing mechanical and electronic systems, your proposed mechanisms have no evidence they even exist, and you are unable to provide any other than the movements you are trying to explain, which is backward reasoning.
Arguing whether it
would (based on nothing but your personal incredulity) is superfluous. Your assertion is entirely unsupported once it is shown that the movement can be explained by things other than gravity. Your assertion it is 'unlike other servo motor driven actions is absurd, and I'd be willing to bet you have indeed seen servo motor activity that doesn't behave in the way you expect because you simply don't recognise it as such. I've seen servo motors used to simulate, very effectively, a breathing creature as an animatronic for a movie. It didn't look even remotely mechanical. That's one of the many many fun things about fine control of such motors.
a. Why would a tracking algorithm switch suddenly from slow-careful tracking of earth, to flinging wildly off-target...
Line of sight blockage by the vehicle during pitchover, or spurious input, or a glitch.
c. Then hone in, with loose (non rigid) motions that approximate that of a pendulum to a direction that is OFF TARGET.
Because it is no longer being used.
Is it POSSIBLE it was a bug, and the servo-motor produced this exact unreasonable behavior -- YES, I think that MIGHT BE POSSIBLE.
Then no further argument is needed. If it is possible for it to happen due to the existing mechanics of the system it is NOT evidence of gravity.
Debates are NOT supposed to end in Agreement.... they usually don't.
Not when the debate is between reality and fallacy. There are complex issues that can be debated that don't have obvious right or wrong answers. This is not one of them. Either Apollo happened or it didn't. Either this event is evidence of fakery or it isn't. There isn't an 'agree to disagree' outcome here.
