Yes, I must admit I am a hopeless Lost in Space fanatic, have been since it first aired in '65 and I was all of seven years old. When Star Trek came along, I remember watching some of it, but most of the time it was over my head. I did not start to appreciate it until I was older and it was already in syndication. But LIS was magical to a seven year old and it still has a place in my heart to this day.<br /><br />I too have fantasized about building, and living in, a full size replica of J2. I have even doodled some blueprints for it and stashed them away somewhere for when I win the lottery. <img src="/images/icons/wink.gif" /> My concept is to build it as it appears landed in most episodes where the lower deck is not seen from the outside and would have to be below grade level. To accomplish this, I would excavate a circular hole 8 to 10 feet deep and pour concrete walls to serve as the enclosure for the lower deck and the footer for the upper deck and outer hull, which would be constructed of plate steel. The lower deck would actually be below grade and constructed like the basement of a house. <br /><br />I think it is physically impossible to build both the upper and lower deck within the package of the actual hull and maintain the proper scale, because as someone here noted, the inside of the ship is much bigger than the outside. This is because the original pilot episode, (when the Jupiter 2 was called the Gemini 12), there was no lower deck. The lower deck was added later, along with Dr. Smith and the Robot. In fact, I have heard one of the cast members note, (Bill Mumy I think), that the sets for the upper and lower decks were actually located in different buildings, and when the characters would exit a scene using the ladder or glide tube the scene would be continued sometimes days later at the other location.<br /><br />Oh well, just some musings from a die hard LIS junkie, I could go on like this all night. <div class="Discussion_UserSignature"> </div>
