Yes, are there any more thoughts on this matter?
Visual observation of the sun's position simply cannot be trusted. Look up the expedition of the Novaya Zemlya, They observed the sun in the "wrong" position for two weeks. RE people write it off as a "superior mirage" - even though the sun was supposed to be below the horizon at the time, the atmosphere somehow magically bent the light so that the sun was visible. Only way to reconcile the observtion with the stated curvature of the earth.
Well, if you can use atmospheric distortions to write off results that don't fit your paradigm, I can certainly use them to write off results that don't fit mine...
