Scientific Flight Rules and Murphys law

The major cause of crashes is a screw loose somewhere above the pilot seat.

Good pilots do NOT do whatever My Rice Krispies tell him to.

Jet and piston engines work on the same principle: Suck and squeeze, blow and go.

* The propeller is just a big fan in front of the plane used to keep the pilot   cool.
 When it stops, the pilot start sweating.

Nothing is foolproof for a sufficient talented fool.

Airspeed, altitude, or brains; you always need at least two.

There are not many bold and old pilots around.

Pride is what pilots have. Vanity is what others have.

* Every takeoff is optional.  Every landing is mandatory.

* Flying isn't dangerous.  Crashing is what's dangerous.

* The ONLY time you have too much fuel is when you're on fire.

* The propeller is just a big fan in front of the plane used to keep the pilot   cool.
 When it stops, you can actually watch the pilot start sweating.

* When in doubt, hold on to your altitude.  No one has ever collided with the  sky.

* The probability of survival is inversely proportional to the angle of   arrival.  
The larger the angle of arrival, the smaller the probability of   survival and vice versa.

* Stay out of clouds. Mountains may hide out in clouds.

* If you push the stick forward, the houses get bigger.
 If you pull the stick   back, they get smaller.
 That is, unless you keep pulling the stick all the   way back,
then they get bigger again.
