There is no such thing as the UA acceleration.

The gyro drop proves that the rotating gyroscope falls faster than its non-rotating counterpart (A-10 gravimeter used).
Nowhere in the Principia does Newton mention attractive gravity; on the contrary, he dismisses this known "law" in no uncertain terms:
A letter to Bentley: “That gravity should be innate, inherent, and essential to matter, so that one body can act upon another at a distance through a vacuum without the mediation of anything else, by and through which their action and force may be conveyed from one to another, is to me so great an absurdity that I believe no man, who has in philosophical matters a competent faculty of thinking, can ever fall into it.”
