The concept of free will vs predetermined destiny is a question that only is based on belief and not a hypothesis that can be proved imho.
As far as personal opinion I believe in free will, but to prove free will is as illusory as trying to prove evolution to a creationist, Loved Ben Carlsons comment n Oprah today, how could it not be intelligent design if creatures are able to adapt to their environment.
The earth axis is at a 23 Degree tilt as noted by many sources, so at a 0 degree tilt my hypothesis is there would be no Coriolis effect. Sorry if you missed the NASA reference that from another reference point ie space "there is no deflection and the motion is a straight line."
According to NASA "To an outside observer, who is occupying another reference frame, there is no deflection and the motion is a straight line."
Would this mean observed from space the path of a missile is straight?
How could this be explained? No effect when shot along the eqauator.
Because of the axis tilt of earth and earth's rotation, from the time of the missile firing and hitting ground the target has moved, thus necessitating corrective calculation attributed to the coriolis effect.
Would there be a coriolis effect if the earth's axis was not tilted? I think not.
