there has been a cooperation between NASA and ARRI in the early 60ties.
ARRI had been asked to build around 400 units of a film camera to be used to shoot the burning process of the rocket boosters.
The project was called "VERTEX" (for Vertical-Experimental-"Take-Off"-Camera).
Last year ARRI acquired a re-built VERTEX form a German collector.
Besides an ARRI retiree backing the story, we are lacking any internal project records.
So our question to you out there: Is there anyone, perhaps a NASA veteran, who could shed some light on this project?
A picture of the camera actually mounted on a rocket (Apollo?) would be of great interest.
