Incidentally, given a copy of the Victor drop CinC SAC had it displayed at Offutt and then requested a similar photograph from the Vulcan, that too was not without problems as the first drop at Aberporth was dropped by the Nav Rad, as outlined by Orionsbelt, before the chase photographer was ready. Poor briefing as the drop was supposedly to be controlled by the range controller.
After the successful drop of 21x1000 lb inert another drop was organised for El Adem range with HE now that was a sight with a wall of flaming sand. I have the slide somewhere.
Years later further drops were organised and 21x1000HE retards dropped from 300 feet over Epi Bay was a sight to behold, again with a mile long line of water spouts.
