阅读下列短文, 从所给的四个选项中, 选出最佳答案.
Have you traveled on any of the new giant airplanes? If you have not been a passenger (旅客) on one of these planes, try to imagine a jet which is more than seventy meters long and more than five stories high at the tail. Such a plane costs at least twenty-five million dollars to build. It costs at least $6, 000 to fill this giant with fuel (燃料).
Inside, the giant jet looks more like a great theater than a plane. It has six kitchens, and they are all needed when the plane is full of passengers. The jet holds more than 400 passengers. Imagine that number in one jet plane!
Is there any danger that the jet's engines (发动机) will fail? Fortunately, the planes appear to be quite safe. On each plane there are twice as many engines as the jet needs. If two engines fail on the same side, the plane can easily use its other engines to land. There are also two mechanical pilots (机械飞行员) to take charge if the human pilots cannot fly the plane.
