Sometimes you really have to wonder how these things fly. Actually I think that the more you know about air planes, the more you wonder just how in the world don't 50% of them, at least, crash.

I remember one class back in school, it was about materials, I can't remember just what the topic was exactly but I remember learning about the fact that there are some cracks that appear right away and they're actually really useful because they indicate visually if the plane is still good to go or not. They're the ones who, partially, make sure that the whole system is safe... but I bet a lot of people would feel safer flying in a plane with a pristine surface than a cracked one.
( +2 - catching up with the moon, or was it the other way around? )
In other news, some things can always be expected. Just as you can be pretty sure that the local commuter trains will be messed up at the first sign of snow even though snow comes every year, Heathrow was a huge mess because of fog. Fog!
