Systems knowledge is important. What you dismiss out of hand today might have saved your life tomorrow, had only you thought it worthy.

Something you may learn one day is that so long as everything is working, it's all theoretical, and when it's not, that knowledge is all functional.

Even something as trivial as the potential interrelationship between an obscure software trim subroutine, and say, an angle of attack sensor.

Whenever I hear someone say "I don't need to know that," what I really hear them say is "I'm a bloody idiot."
