Let infinite discretion govern thy movement near the ground, for vast is the area of destruction. 4. Blessed is he who strives to retain his standards, for without them he shall surely perish. 5. Thou shalt maintain thy speed whilst between ten and four hundred feet lest the earth rise and smite thee. 6. Thou shall not make trial of thy centre of gravity lest thou dash thy foot against a stone. 7. Thou shalt not let thy confidence exceed thy ability, for broad is the way to destruction. 8. He that doeth his approach and alloweth the wind to turn behind him shall surely make restitution. 9. He who alloweth his tail rotor to catch in the thorns curseth his childrens children. 10. Observe thou this parable lest on the morrow thy friends mourn thee.
