Keep looking around. There's always something you've missed. It's the law. And it's a law that is not subject to repeal. The three most useless things to a pilot are the altitude above you, a runway behind you, and a tenth of a second ago.
Every takeoff is optional.
Every landing is mandatory. If you push the stick forward, the houses get bigger. Flying isn't dangerous. Crashing is what's dangerous. The ONLY time you have too much fuel is when you're on fire.
