Re: The Mystery Inside the TOS Primary Hull Support Pylon
The TMP novel said something (been a decade since I read it)about a criss cross of structural members bulkheads and machines with a few alcoves scattered between them that served as little places where one could be alone for a bit while looking out of a porthole, I don't think that it would be very much different before the 1701 was refitted.
As for connector or seperator, seperation is a last ditch attempt to prevent the whole crew from being blown up so I imagine that the neck is mainly there to keep the two hulls together..
