Sometimes, don't you, when you look way way up high, doncha just wonder, what keeps those darn things up there, and aren't they hanging by a thread, and are they all worried to death in their skins?

Of course, it's all science, the air passing more slowly over the longer, curved surface of the upper wing creates a vacuum thereby dragging the plane upwards and almost making the engines redundant...

But it's still so weird to look up up, way up high, and to think that there's a bunch of people, sitting in seats, all that way up in the air, not, probably, where God intended us to by (or s/he'd have given us wings...)

Think about it...
