I’m really curious: do you have a cite for this? Remarkably, British counterintelligence discovered and captured every single German spy sent across the Channel, turning many of them into double agents.
Of course, the spies you refer to may not have been ones operating on British soil. But either way, I’m curious.
A fantastic early-‘80s British TV series called “Danger UXB” (Un-eXploded Bomb) featured extremely realistic accounts of efforts to disarm unexploded German bombs in WWII England. It also explored the arms race between German fuse designers and the British teams that tried to disarm those fuses.
I’ve seen full episodes available on YouTube and they may well be available elsewhere. I watched this show as a kid with my parents when they aired in the US on Masterpiece Theatre. The entire family was riveted. I can’t recommend the show highly enough.
It was in the back of my mind as I wrote the question at the start of the thread. Completely gripping and entertaining. I often looked to see if it was boxed-up for sale, but glad to know its made it to YouTube.
It ain’t Wendell Willkie!
The cartoon is from 1943, though “gremlins” are attested as early as the 1920s. Wiki trivia is that the color scheme of the gremlin in the cartoon reflects that of U.S. Army Air Forces training aircraft.
