求翻译:HAVE you ever thought of being able to fly around the world in a few hours though it is about 40,000 kilometers? Now, maybe you can. Last Saturday, the American X-43A airplane made its first flight. It reached a speed of 8,000 kilometers an hour. This makes it the fastest plane in the world. X-43A is only three to four meters long, but it’s very heavy: it weights 1,270 kilos.是什么意思? 待解决
