They were going to explode the gadget inside that so if it were a dud, they could recover the hideously valuable plutonium. Thanks! Brian Ehni (Sent from my iPhone)

The photo was taken at Pope, New Mexico, during the unloading of Jumbo. Pope is on the Santa Fe line from Albuquerque to El Paso. okladivjohn@...

 Hi Craig and List Members, Craig, you are refering to this image I believe... https://digitalcollections.uwyo.edu/luna/servlet/s/1xy326 I like the fact that one can zoom in a whole lot for

I think this is a photo from Hannaford, Washington, and not from Los Alamos. It's probably a reactor vessel of some kind. -- Tim O'Connor Sterling, Massachusetts

Makes sense. It’s not the gadget, and there’s no containing the actual nuclear explosion IF it occurs]. Dan Mitchell ==========

Such vessels, including the shell for the “gadget”, were to contain the explosive force of the conventional explosives (TNT, whatever, used to compress the nuclear core material) … should the

Thanks, Don for that clarification. It makes more sense than a containment vessel for the explosion. Bill

That's Jumbo, a large metal casing (214 tons) that was designed to hold the Gadget. The idea was that if the TNT exploded but the plutonium didn't, it would contain the explosion and no plutonium

Bill, Actually the container was designed to retain the nuclear material if the regular explosive went off but the bomb did not detonate. My father was a military officer assigned to the

Actually, Dan, there WAS a vessel designed and built to contain a nuclear bomb... strange as it may seem. Frankly, when I first read about it, I didn’t think it would work, and apparently it was

Clark Propst shares his work on an Accurail HO scale gondola kit in the latest Resin Car Works blog post. He adds a few simple details inspired by a C&NW prototype.

Interesting shots, Claus... one of the most interesting to me was the 7th (I think) shot down from the top which shows a small box on the ground alongside the car... it is a wooden 8x10 field camera
