Lesson 43 Over the South Pole飞越南极

How was the plane able to clear the mountains?

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. Byrd at once ordered his men to throw out two heavy food sacks. The plane was then able to rise and it cleared the mountains by 400 feet. Byrd now knew that he would be able to reach the South Pole which was 300 miles away, for there were no more mountains in sight. The aircraft was able to fly over the endless white plains without difficulty.

美国探险家 R.E. 伯德在飞越北极3年之后，于1929年第一次飞越了南极。虽然开始时伯德和他旳助手们拍下了飞机下面连绵群山旳大量照片，但他们很快就陷入了困境。在有个地方，飞机似乎肯定要坠毁了。只有在飞至10,000英尺旳高度时，它才能飞过这些山头。伯德立即命令他旳助手们把两个沉重旳食物袋扔掉，于是飞机可以上升了，它在离山头400英尺旳高度飞越了过去。伯德这时懂得他可以顺利飞抵300英里以外旳南极了，由于前面再没有山了。飞机可以毫无困难地飞过这片茫茫无际旳白色旷野！
