This came from a thought from the conversation in the Memory Beta Issue thread: When they run through all 26 letters in the alphabet for the Enterprise, what will they call it then? Or will it be the end of the Enterprise name? Say they continue the Enterprise name though, they wouldn't call it NCC 17011 or 17012, since by the time of the D we already had NCC 74656. Will it be 1701-AA, BB, CC or AB AC etcetera? Or would JJ have the last laugh when we start sticking zero's into the registry numbers. Ah HA!
