Does anybody know what those dozen or so tall thin smoke trails are to the right of the explosion? They are present as soon as the initial light blast dies down, and seem to hang around for most of the clip, unaffected by the blast itself.
Several years later this phenomenon was put to use with the aid of smoke rockets launched from the ground seconds before the detonation. This created an vertical array of reference lines against which the progress of the shock front could be photographed.
