7. A Final Failed Demonstration Consigned the Great Panjandrum to the Trash Heap of History

Despite the awkward failed trials, planners still had faith in the Great Panjandrum’s potential as a useful weapon. So the designers returned to the drawing board to work out the bugs. When they finally figured that they had it under control, they carried out a final make or break demonstration in front of an assembly of admirals and generals. As described in a BBC documentary: “At first all went well. Panjandrum rolled into the sea and began to head for the shore, the Brass Hats watching through binoculars from the top of a pebble ridge […] Then a clamp gave: first one, then two more rockets broke free: Panjandrum began to lurch ominously.

It hit a line of small craters in the sand and began to turn to starboard, careering towards Klemantaski, who, viewing events through a telescopic lens, misjudged the distance and continued filming. Hearing the approaching roar he looked up from his viewfinder to see Panjandrum, shedding live rockets in all directions, heading straight for him. As he ran for his life, he glimpsed the assembled admirals and generals diving for cover behind the pebble ridge into barbed-wire entanglements. Panjandrum was now heading back to the sea but crashed on to the sand where it disintegrated in violent explosions, rockets tearing across the beach at great speed.” Unsurprisingly, the project was immediately scrapped over safety concerns.

A lifelong history buff, I developed a particular passion for WW2 history as a child, when I spent hours listening to my grandfather, enraptured, as he recounted his wartime experiences in the British East African Campaign and with the British 8th Army in North Africa.

I graduated with a history BA from George Mason University, then went on to get a JD from the University of Virginia School of Law. After lawyering for a decade, I moved to sunny Rio de Janeiro and a less demanding career, opening a tourism agency in Copacabana.

A big chunk of my free time is spent blogging (you can follow me on Quora https://www.quora.com/profile/Khalid-Elhassan ) or freelance writing, mostly about my favorite subject, history.
