Backtracking slightly, I've been bothered about my supposed recollection that the scale of the Enterprise was changed between 'The Cage' and 'Where No Man Has Gone Before,' so I've dug out my copy of 'The Making of Star Trek' and I think I've figured out where I got the idea. First, from the series format - not dated, but it notes Robert April as the Captain, page 24: (Amusingly, on page 26, the format notes: 'The cruiser itself stays in space orbit, rarely lands upon a planet.' (emphasis mine) So we have a starting crew of 203 and a mass of 190,000, before any design work had been done. Next, in a memo dated August 24, 1964, in the chapter called 'A Blueprint for Starflight,' from Gene Roddenberry to those concerned, page 89: Later, in the chapter about the second pilot ('The Second Time Around'), from Whitfield's text, page 134: (Mass afficionados also take note: the 190,000 weight ship appears to correlate to the 200 foot ship, not the 947 foot ship, even though it is subsequently attached to the 947 foot ship on page 171.) This is what in turn led me to believe that the alteration to the bridge dome was a reflection of this scale change, and that it had occurred between pilots. Could Gene have been unaware of the predicted size of the ship the design of which he had approved, and just taken this long to correct it? What does this all mean?
