How about this. an" Egg Shaped" shuttle for the next build?
Okay,You may think I am weird.
You've heard of " Kinder" Eggs? Two eggs equal top and bottom of an egg shaped shuttle. What! Yup. Small, yes, but an idea that worked for a Model RailRoad layout. A small " Egg" shaped U.F.O. Crashed in a farmers's field and the U.S.Army was loading it on a Flatcar to take it away to study.
Now the nice part of this is you can configure portholes or windows the way you want. Because the thing is in halves you can scratch whole or part of the interior and use mishapen H.O. Figures for the Aliens! Or use putty to reshape them to your liking.
You can add all kinds of protuberances or leave it a smooth Gravitic Drive ship. Gravitics drive needs no protuberances and requires only three short legs for a two man lander.
Not every U.F.O needs the be saucer shaped either, remember. Some are shaped like Bananas or Sausages too! Some even have been described as looking like the Pod-Shaped water towers too!
The boarding ladder can be under the equator of the craft too. If you want ,take some clear sheet and cut out an egg shaped piece that is say a sixteenth inch bigger . Mount short clear posts to make it appear to float and color the ring with candy paint with no undercoat in very thin amounts to represent the Colored Ring around the outside of the ship. Simple, Cute and an awesome little U.F.O.
