Resources on Coriolis forces use in external ballistics

Over and over and over and over and over again the experts tell you that at VERY LONG ranges the Coriolis and Eötvös effects matter and are used in the calculations used to aim ballistic artillery and rifle fire... to deny the VAST body of evidence on the word of some anonymous & unverified source is utterly ridiculous and just shows profound epistemic bias.

Deconstructed - Auguste Piccard: “It seemed a flat disk with upturned edge”

Image
Deconstructed - Auguste Piccard: “It seemed a flat disk with upturned edge” Is it possible he means it looked like an upturned disk?  As in, you see a bit of horizon curvature? Stratobowl image from 1935 The human eye has a wide field of view so you see a bit more of the Horizon Circle than most images and thus more curvature, all else being equal. One reason for this is that this is NOT the "curvature of the Earth" -- this is the curvature of the Horizon Sagitta viewed nearly on edge .  This is a mistake I constantly see people making.  So it's not a circle of 3959 miles diameter that curved downward, but an OVAL that you are in the middle of with, in this case, a 300 mile radius and viewed on edge at a 4.8° angle -- and this oval curves 360° around YOU. As to why it looks flat, it's because the terrain is far away and the curvature is fairly slight and you're looking down on it.  We just cannot see the geometry under these conditions.  You can't even see the...

1958 Encyclopedia Americana quote "[Antarctic] DOME 13,000 feet high" / Admiral Byrd quote

Image
Flat Earth Claim " The (Antarctic) flights proved the inland areas to be featureless in character with a DOME 13,000 feet high at about latitude 80 degrees south "  (You should feel kind of mad right about now?) Reality Here is what he actually said about this: superimposed by a great dome of snow and ice , and toward its center reaching in excess of 13,000 feet elevation. Confirmed by modern elevation maps of Antarctica. Domes are geologic features . We done with Flat Earth yet? I doubt it, their ignorance is fathomless.
