The Ten Commandments of flying helos :
  - He who hath inspecteth not his aircraft gives angels cause to concern him.
  - Thou shalt not become airborne without first ascertaining the level of thy propellant.
  - Let infinite discretion govern thy movement near the ground, for thy area of distruction is vast.
  - Thy rotor RPM is thy staff of life. Without it, thou shall surely perish.
  - Thou shalt not let thy confidence exceed thy ability, for broad is thy path of destruction.
  - He that doeth his approach and alloweth the wind to turn behind him shall surely make restitution.
  - Thou shalt maintain thy speed between ten and four hundred feet lest the earth rise up and smite thee.
  - Thou shalt not make a trial of thy centre of gravity lest thou dash thy foot against a stone.
  - He who allows his tail rotor to catch in the thorns, curseth his children and his children's children.
  - Thou shalt not fly unless thou first have a type rating for thy craft!
