I have this theory that, to us the world is a flat thing we stand on, but to birds it is a cliff they cling to, a huge ball and they cling to the side and then fall off and fly and glide.

我有一种想法，就是对我们来说世界是一个我们所站立的平坦的东西，而对鸟来说是一个它们所依靠的峭壁，一个巨大的球，它们依靠在边上，然后离开、飞翔、滑行。

That means that the jet can fly at a relatively high 600 to 800 feet spraying its payload as it goes, making it safer in theory, even suitable for firefighting at night.

也就是说，这架喷气式飞机可以在相对较高的600至800英尺，在飞行过程中喷洒出有效荷载，从理论上讲更加安全，甚至适合夜间扑火。

The aerodynamics of small things are, however, different from those of larger objects (according to classical theory, for example, a bumblebee should be unable to fly).
