[1967 R50/2]

My personal preference:

I do not think they will find Earth until the very end of the series, and even then the question of what state earth is in will remain open ended.

Z-Man, the quote that you cite is interesting...interesting because it might actually be a hole in the plot.

1 It is recounting what happens to the 13th tribe once they found earth...but being nobody (before this episode) knows where earth is, how would they know what the hell they saw? They are the "lost tribe" after all so how was this communicated back to the colonies to wind up in "The book".

2.And why would the colonial flags represent constellations as seen from Earth when clearly they would not be seen the same from anywhere else?

Must go....geeking myself out.
