This was all on film cameras (nikons). We had film scanners (and film printers for creating presentations), the works (a special tripod head was used for the interior shots).
This was back when you had to use MPW (mac programmers workbench) to do the actual stitching.
I'm sure all those photos are sitting in some government office still (or maybe in that center) and could even be reprocessed today, in a MUCH easier manner.
