1/2" steel shielding

[Flookie]

I'm haggling with another Apollo denier and he keeps bringing up "1/2 inch of steel" as inadequate shielding against the (presumably) VAB. I say presumably because he isn't clear in his mind between heat & radiation or distinguishing between a Saturn V and the Apollo craft. It's possible he's referring to the thermal shielding on the CM base but I was explicit in explaining that was heat shield and what actually was used as shielding. Can anyone tell me where this 1/2" steel originates and whether it does refer to some aspect of Saturn V or Apollo?

Also, he keeps referring to an interview with Alan Bean that indicates Bean didn't know where the VAB were. I understand it's a questions about Apollo spliced together with an answer about Skylab (whether it passed through the VAB?). Can someone enlighten me about this interview?

Sounds like it came straight out of his tuckus, truthfully speaking.
Apollo spacecraft walls were made of several layers of different materials.

Or the old 'you need lead for radiation shielding' line.

Thanks. His original idea was appropriate for a nuclear bomb and a weblink to back himself up. I had to explain the different sorts of radiation to him, including where infra-red fitted in. He does acknowledge he has no idea how intense the heat or radiation would be or what is appropriate shielding against either but is adamant 1/2" steel is inadequate for the solid reason that he doesn't think it is. I can only think he is either imagining something or it refers to the nose of the Saturn V but I have no desire to chase up blueprints.

Any idea about the Bean interview? I found a reference in earlier discussion that it was spliced film made by Sibrel but that was it.

Here is a pdf of the construction.  .5" is the smallest thickness widening to 1.5"

The outer structure is the heat shield and is made of stainless steel brazed honeycomb brazed between steel alloy face sheets. It varies in thickness from .5 inch to 2.5 inches

Here is the clip you are talking about.

Cuts aplenty.

And how did that interview end? Here is how (NSFW)

Yup Sibrel pulled his same swear on the bible crap as he did on Aldrin. Al Bean chucked him out of his home. Aldrin decked him.

My Ren faire boss has a new pin that I feel fits into this conversation--"A day without radiation is a day without sunshine."

Thanks!

That pin is just rad!

Haha, funny because absolutely true.

I've suggested that we need the corresponding pin, "A day without sunshine is, like, night."
