      I'm showing 1 inch thick for Aluminum 7079-T6 to reach 3000 feet
      at a usage factor of .8<br>
      I believe that equates to around 1,850 pounds with about 1,800
      pounds of payload.  If you use ABS recommended .67 usage factor
      you have to bump up to 1-1/8 inch thickness.<br>

        <div>I know there was the aluminaut that was made of aluminum.
          What is the possibility of using aluminum instead of HY-100? I
