It's not so hard to find aviations (related) sites, there must be hundreds of them.
This is however a personal selection of:

rather unknow, very interesting, very useful, very nice sites and stuff.

Explore and Enjoy!

Every pilot understands the importance of good weather knowledge. Clouds tell us a lot about the weather. This site is a Cloud Atlas filled with lots of wonderfull pictures! How many clouds can you still identify?

Airplanes aren't always used for flying....

Laughing is told to be good for health. Good health is necessary to keep your pilot license. So, when it comes to humour try this.

The creativity of men has no limits. Have a look at some unusual aircrafts.

Morse code is used in aviation to positively identify radio beacons. We mostly look up the code on a chart or other printed matter. Morse code is technically the simplest way to transmit messages. A flash light can already do the thing. (could be handy during exams ;-)
For those who have the courage to learn the code this morse code simulator can come in very handy.

"This is a man's world, but it wouldn't be nothing, nothing without a woman, or a girl" (James Brown). Indeed, what would aviation be without the glamorous stewardesses?

Murphy's Law.
We all think that it means that whenever something can go wrong, it will go wrong.
Wrong!
It means that whenever you're designing or building something, you should investigate in advance all that can go wrong, in order to prevent it from going wrong!
The link between Murphy and aviation, you wonder? Murphy was a Air Force engineer during the fifties and that where his law originated: Murphy's real law

Fascinating simulated film, based on radar plots, with real world air traffic during 24 hours. The yellow dots are, of course, airplanes. Remark the traffic coming alive during the day.

James Bond (007) has always been synonym for exciting scenes with special vehicles. You should see the flying car from "The Man With The Golden Gun", and many other air vehicles used in the James Bond films.
