There is an interesting book: “By the Seat of My Pants” by Dean C. Smith. He was a pilot on one of Admiral Richard Byrd’s Antarctic expeditions around 1929, when they were first to fly over the South Pole. According to Smith, Byrd was a pilot (naval aviator), but not a very good one. They didn’t get along. I had a friend who also knew Byrd up on the coast of Maine, where he was regarded as a sort of lovable eccentric. But he did a great deal to open up Antarctica to exploration.
Have the Mastodons ever been found that they saw?
Incredible what men have done under extreme circumstances.
