Near the village of Hanbury is RAF Fauld. Once it was a munitions dump: now it's a crater. Here's why. (I'm indebted to authors, archivists and aerial crews for this video: here's a full bibliography and list of image credits!)

NOTES: "Brass chisels can cause sparks" is a summary of the inquest's findings. For those in the comments, here's the full version: "in all probability the work of chipping out the C.E. [composition explosive] Exploder from a 1,000 lb M.C. bomb, using a brass chisel, was the cause of the explosion. It is known that C.E. will explode easily if struck between brass and steel surfaces". In this context, 'brass chisels can cause sparks' does make sense! The inquest looked at all the available evidence and judged that to be by far the most likely explanation (and the only one that made sense given all the facts). 🟥 MORE FROM TOM: https://www.tomscott.com/ (you can find contact details and social links there too) 📰 WEEKLY NEWSLETTER with good stuff from the rest of the internet: https://www.tomscott.com/newsletter/ ❓ LATERAL, free weekly podcast: https://lateralcast.com/ null ➕ TOM SCOTT PLUS: null 👥 THE TECHNICAL DIFFICULTIES: null And if you've read this far, I'd like to add a quick note: I love it when I get to actually research things for a video. For the first time, I went to the British National Archives, and got to handle original documents from the 1940s. It felt like quite a privilege to be able to read the first person accounts, and to look at photographs and documents that have been sealed away for years.
