A manager at Boeing I used to work for was involved with this stuff
and told me about it.  There were various cameras mounted on the early
Saturns to get engineering data.  The one he particularly worked on
was the camera looking -into- one of the SI-C tanks to watch the fuel
slosh.  

The cameras were ejected from the rocket and then fished out of the
ocean.  If they were left attached they would probably gotten broken
on impact or sunk with the rest of the stage.  They used movie film.
