As a schoolboy during WW2 I lived approximately 20 miles or so from the RAF No 21 MU Bomb Dump, we did not know what actually went on there at the time, secrecy was paramount I suppose. 194 Italian POWs worked at the dump along with RAF types. Apparently safety was rather lax, and almost no officers were in attendence. Eye witnesses reckon that one of the RAF people was seen to be removing detonators from bombs with a brass hammer instead of the wooden mallet that he should have used, but its still only conjecture, even after all of these years no one knows for sure what created the explosion. The explosion occured at 11 minutes past 11.0am, 4000 tonnes of ordnance exploded, killing at least 75 people. The dead included Italian POWs RAF bods, and 31 people died in the adjacent Fordes Lime and Gipsum works, they died when the factory was engulfed in mud and water after the nearby reservoir burst its banks. The resulting explosion was the largest non atomic event ever to have happened. The munitions were stored in the old gypsum mine that ran underneath Upper Castle Hayes Farm, the farm and all its occupants, animals including 200 cattle just vanished.
Two more farms and nearby cottages were extensively damaged. The resulting crater is 400ft deep and 0.75mile wide. I am a member of The Burtonwood Association, and on reading one of my publications of The Burtonwood Times I came accross an article that had been submitted by an ex-G.I. who at one point during his service had been stationed at Fauld, by then the American army had taken over the dump for storage of their ordnance. He had written to say that although he had been stationed there, and knew that something terrible had taken place, the security was so tight that he had no information. This was some 60 years after he had left the place, I e-mailed him all of the information, and he e-mailed me back to thank me for providing him with this information that cleared up something that had bugged him for all those years............. The wonders of modern technology. The site can still be visited, but it still belongs to the MoD and its fenced office, the signs inform you that there are still many unexploded bombs on the site.
