Very funny.

More seriously most vaults were suppose to support up to a 1000 dwellers for at least 20 years if not longer and survive a direct strike.

That makes them extremely complex.

While there was a standard design, there would always be variations due to local conditions, local suppliers, and design improvements.

The vaults would also need to be maintained until occupied so changes and repairs to the vaults would be ongoing till the day of the war.

Likely 99% of the vault tech employees and contractors had no idea of the experiments.

All you would need is a small group of scientist to come up with the experiments and monitor the results, a few engineers to design the implementation, a few overseers for experiments where the overseer was in on the experiment (likely already a part of the experiment team) and a few techs for general support and to handle the really weird stuff (like whoever installed the panther).

I bet 90% of the time the techs that did the final experiment installations had no idea what the changes they made would actually do.

A last minute change after most of the vault had been built and tested wouldn't have raised an eyebrow.

For vault 12 with the door that wouldn't seal, all you had to do is after the final testing is done, have a part on the vault door replaced with one that is designed to fail.

For other vaults, all they had to do was manipulate the dwellers assigned to the vault or what supplies were sent to the vault.

There was a case not far from where I live, back in the 1970's, documented in "The Body Farm" by William Bass. The owners of an old plantation house noticed someone had disturbed a old Confederate grave on the property. They simply thought it was grave robbers. They investigated further and found a body buried in a shallow grave on top of William Shy's grave. It seemed someone tried to dispose of a body, burring it on top of this Confederate grave. They were sure the victim was a wearing a waiters outfit or uniform. Long story short, it was grave robbers and it was the body of William Shy, the Confederate soldier. The clothes were so well preserved, they thought the body couldn't have been buried over 6 months, been over 100 years. Doesn't matter how much bacteria there is as long as the exposure to oxygen is limited and if the scientist was trapped in that vertical shaft and consumed all the oxygen, then LeBurns is wrong, sorry.

All this discussion of rotting lab coats, badly stained, seems to assume they are made from cotton.

A lot more likely would be 100% synthetic, coated with a superhydrophobic layer.

That would be stain-proof, and good for 1000 years at least.

At least that is what I will be wearing, while working in the vault.

Also, the flooring is grated, so any liquids would seep down and out the grates, so the top of the coat could possibly be unstained.

Exactly, Thank you. There were no synthetic cloth back in the 1860s, referring back to my previous post.

This is still fallout 4 you are talking about, right? You know, the game?

Advance 2070 materials.

Yup

You look at the space age materials we have now in 2015 and compare them to what we had in 1960 and it is not so far fetched that material that are 55 years more advanced would be almost impossible to stain.

I'm going with advanced 2070 exterior paint with nuclear bonding to explain how all the wooden building have survived 200 New England winters.

Don't forget that if it is a Vault-Tec labcoat, it would need to be blood stain proof.

If the scientist is exposed to lethal radiation than its safe to say that his body and the micro-organisms are dead...Sealed in a shaft that may in fact be sterile or close enough...Plus no oxygen air flow and he is wearing a synthetic lab coat.

LMAO to get so adamant about a fictional setting. Being a mircrobiologist I know better, but hey, if you want to dream then dream!

Arrogant much? It's real easy to just type "LMAO" and basically call someone a liar. Go read the [censored] book. I'll take Dr. Bass' word over yours any day. Then you can tell him he's dreaming. It has been well documented that oxygen free environments prevent decay. You really want to argue this?

Good,Goood...(emperor Palpatine laugh)
