Of course the presence of SOMEthing down there -- a machinery level if not a full-fledged deck -- was hinted at from the very beginning. In "The Reluctant Stowaway" (and indeed the pilot as well), the narrator comments, "Here on the lower deck, pulsating with unbelievable force, are the great atomic motors that will carry the ship to new worlds" while the camera aims at the flashing radiation-warning lights on the floor of the 2nd level. But who would have though a whole deck! For that, the imagination of a 3rd-season writer was required....Speaking of the crash landing, in the original concept this was to have caused severe damage to the hull on one side (about the 4 o'clock position if one were looking down on the ship and the front windows were at 12 o'clock). Scant evidence of this remains in the form of a few still images from the pilot. Fortunately for the Robinsons, plans changed and massive quantities of SuperGlue were not required to render the ship spaceworthy again.   See 3 other replies

ha, some of you are so lucky to know Jupiter2 had 3 levels. It's 30 years later, and only now did I see the episode with the reactore core. I guess the network where I lived must have never shown that one,because I remember rushing home from school to watch it everyday.I do remember even as a child wondering about the 2 levels. I think my kid brain always assumed the crash landing had buried a significant part of the craft.   See 3 other replies

The list is long -- though the love is deep!Regarding your first issue: never mind that the Robinsons' vast "junkyard in space", pardon the expression, seemed magically to regenerate after they left Priplanus (or what was left of it) at the end of Season 1 -- how did they cram all that stuff into the Jupiter 2 in the FIRST place?!? As for the Space Pod, perhaps we can simplify matters by assuming it just didn't exist in Season 1 (no, don't ask me how!), since not only did we never see it then, but surely Professor Robinson would have used it for his scouting mission ("Island in the Sky") in preference to those pathetic parajets. And as for the Chariot, I've always been stuck by how quickly its assembly seems to have been accomplished (it must have been fast, because they needed to begin searching for John ASAP) and the absence of tread tracks around it when the first drive off -- talk about modular!Now to your second point, concerning the Jupiter 2's multiple levels. As I commented a while back in this forum, although the viewer could be forgiven for concluding that the J-2 must work something like Dr. Who's TARDIS, opening up into other dimensions, a spacemodeler named Jon Rogers has evidently figured out how to reconcile all three levels in normal Euclidean space! See "The Saucer Fleet" by Jack Hagerty & Jon Rogers (CG Publishing, 2009) for the amazing details.Of course this only scratches the surface of all the glitches in LiS, but I like to think that enumerating them all actually enhances one's enjoyment of the series. works that way for me, anyhow.   See 3 other replies
