Ferry flight tailcone question

All the posts about the SCA got me thinking about the tailcone they
attach to the orbiters when they're being ferried by the SCA.

Is it stored at KSC until it's needed to ferry an orbiter back to
Florida? How is it transported? Is it shipped on a cargo plane or can
the SCA accomodate it somehow sans orbiter?

There's this big, empty space inside the SCA...

I understand the cone folds somehow so it can be carried inside, I'd
guess in the cargo hold as the hatches tend to be bigger.
