当年美国的间谍飞机的飞行高度六万八千英尺,那时苏联的火箭按说还达不到这个高度,却把U-2飞机击落了,美国人感到很奇怪,世人亦不知道底细。这到底是怎么一回事呢?美国的U-2飞机在苏联上空飞行了四年,拍摄了很多导弹基地的照片。
When the U.S. spy plane flew 68,000 feet, the Soviet rocket was still said to have reached that altitude but the U-2 plane was shot down. Americans were weird and the world did not know the truth. What exactly is this? The U-2 aircraft of the United States flew over the Soviet Union for four years and took pictures of many missile bases.
