About

This film explains how cameras are positioned to record and later study blast effects (with smoke trails) and thermal fenomena (with ground dust lifted by heat).

Quite techinical, with lots of footage directly from "Operation Tumbler-Snapper" of 1952 (avaiable also here on Archive.org).

Human-made No record of this work says a model made it. What this means.
