| muscular-skeletal makeup of a bird's wing, to | | | | race you were depleted and literally running on |

| water flows, created current from AUV, or | | | | aircraft eats the inside of the wing which is made |
| increased back pressure from forward | | | | of a poly type plastic, it is dissolved, thus the |

| Energy-Efficiency:In our hypothetical | | | | was continuous. One variation on this theme is to |

| would wiggle and move forward and thus be less | | | | in the end, providing forward momentum and |
| detectable... with less mechanism or springs and | | | | thrust. Since the chief purpose would be for |

| to propel. Thus weight savings-- not that it's a | | | | the mission and attack sequence. Meaning, the |
