但哪个发明更神奇，空间技术还是航海图呢？

But which is the miracle invention here: the space technology, or the chart?

我们是船上的乘客，尽可不必去过问那航海图与罗盘针。

It is not for us who are passengers, to meddle with the chart and with the compass.

如果要你在黑夜飞行，你就该长一双猫头鹰的眼睛！你就该有航海图一样的头脑！

If you were meant to fly in the dark, you'd have the eyes of an owl! You'd have charts for brains!
