It has fueled wild speculation for years and I would bet there's a very tiny spark under all that smoke: Operation Highjump sure seems to be a more of a "better safe than sorry" military operation than serious Antarctic exploration, a move just in case the Axis had some holdouts biding their time in the cold. Even the abrupt departure fits. ("Mission Accomplished" or "Nobody Home?" You cleared for that?)
An amazing venture either way.
