How did they do this video?

A monochrome video, not film, about the 1964/65 New York World's Fair.

It seems to have been done entirely with an image orthicon camera (or cameras), including on-ride sequences in the General Motors pavilion.

Questions that come to mind:

1) How did they get the camera working on a moving dark ride conveyor?
2) How did they get the signal out / onto tape?
3) Any other technical issues that pop into someone's head?

It seems like this should have received some sort of technical award, but I haven't found any evidence of one yet.
