Admiral Byrd / Operation HighjumpAtlas
Science & Technology · Space & cosmology
Accounts claiming Admiral Richard E. Byrd, Operation Highjump (1946–47), and later Antarctic Treaty controls reveal a south-polar ice wall, withheld zones, or encounters with advanced craft or bases—versus naval, polar-science, and treaty histories treating Highjump as a postwar survey/training expedition, Antarctica as a continental ice sheet with coastal ice shelves, and ice-wall / diary / UFO-battle packages as later flat-Earth and hollow-Earth overlays.
