I suspect the cases are grounded but perforated to allow airflow but
shield the contents from radio interference --- is that right?

What are they called?

Doghouses. That's not their formal name but it is what we call 'em.

Thanks! What would they be called in a catalogue (for example)?

RF shield can, maybe. That googles pretty well.


"screening can" has been in common usage for some time.

That sounds sort of British to me. I wish you guys would learn to talk
proper
American.


If it weren't for British English, you'd all be speaking French.
If it weren't for American english, you'd all be speaking German.

How would he manage that?

Germany had no nuclear capability and the V2 didn't have the range or
anything other than a primitive guidance system to make it a threat to
the US.

Why?

Peenemunde was never a threat to the US, as I understand it, ergo your
"flattening it" was only interesting locally.

The Nazis were actually planning an ICBM to hit New York, Projekt Amerika, but
they weren't too serious about nukes. Hitler and his boys were skeptical of what
they called "Jewish Physics."

A poorly guided missile, with a chemical warhead, would kill just about zero
people per shot. Even a nuke wouldn't be likely to do a strategic amount of
damage: the USA is BIG.

I can't say I've heard that one before, but it works.

After all, people have called "IF transformers" "IF cans" and obviously
the "can" is in reference to the shield, not the actual transformer
inside.

My belief is that the almighty British empire's inability to put down
the upstart Yankee doodles during the revolutionary war put their
knickers in such a bunch that some of them have passed down that
resentment through the generations.

On top of that, our pulling their fat out of the fire - not once, but
twice - further exacerbated their feelings of inadequacy.

So, who better to rail against than those who kicked their asses in
the beginning?
