Over the South Pole
In 1929, three years after his flight over the North Pole, the American explorer, R. E. Byrd, successfully flew over the South Pole for the first time.
Though, at first, Byrd and his men were able to take a great many photographs of the mountains that lay below,
they soon ran into serious trouble.
At one point, it seemed certain that their plane would crash.
It could only get over the mountains if it rose to 10, 000 feet.
