Conspiracy

Mystery 'fog' sprayed on US cities in 1950s linked to secret Army project

70 years ago, neighborhoods in several big US cities were sprayed with a mysterious chemical compound.
The experiment, which took place in parts of St Louis, Missouri and Fort Wayne, Indiana as well as in several other cities in both the US and Canada, created a thick, foul-smelling chemical fog that residents reported had stuck to their skin, coated roads and rooftops and had made children sick.

The purpose of the experiment was to study how chemical weapons might spread through Soviet cities during the Cold War and while the chemicals used were supposed to be harmless, it turned out that this was definitely not the case.

The spray contained zinc cadmium sulfide (ZnCdS) - a powder known to cause cancer.

The Army had maintained that the amounts used were low enough not to cause harm, but a key report detailing the health risks from the experiment later went missing, leaving doubts over whether the Army was aware that what they were doing was harmful to local residents.

In later years, people who had actually lived in these areas at the time would come forward to tell of how they and their family members had suffered from a disproportionate number of health complications, in particular from various different types of cancers and respiratory diseases.
"They didn't ask our permission," said former Pruitt-Igoe resident Cecil Hughes. "We didn't ask for them to spray us. My government used me like I was a Guinea pig."

Another former resident, James Caldwell, described suffering from a rare form of lymphoma.

"You couldn't even see through it; it was that thick, and it would adhere to our skin," he recalled.

"And as far as the guys on top of the buildings, they tried to portray them to us as maintenance workers, but what are the maintenance workers doing in a hazmat suit?"

"They had masks and goggles."

Sadly, however, despite official admissions that the spraying took place, no definitive case has ever been brought against those responsible for the harm it caused.

Yes, that's why I said "neighborhoods." A neighborhood is a part of a city, not the whole city. In the 1950s racially segregated neighborhoods were areas where minorities would live, sometimes specifically forbidden to live in other parts of the city with a tactic called "redline" or "redlining". St. Louis is especially famous for their redline policies.

Welcome to the US...the list of tests ran on the population without consent, approval or anything else is infinite...

It was my understanding the bacteria spread all over san Francisco and many surrounding areas. Doesn't sound like it was aimed at a particular neighbourhood.

Yeah, I only brought up the SFO incident because it's 1) entirely messed up that someone thought that was an OK idea idea to do to an entire city, and 2) that it was unfocused and bacteria, in contrast to aimed and toxic chemicals as was the incidents highlighted in the article.

So they used those 1950s “smart” munitions to surgically spray only parts of a city, e.g., by the jazz club, and not amorphously distribute the chemical in, say, a line across the city, subject to wind and other environmental vectors - interesting.

Munitions? Where did you get that from? Because it's not part of any reporting at all, so you had to invent it.  People in suits went around spraying the chemical. It's all extremely well-documented. There's photos, documentaries, interviews, testimonials. It's like you're trying to fight about clouds being in the sky.

It's not OK? Hmm, I'm sure those government agencies have adjusted their OPLANS for domestic research. Luckily the pigs at the trough have been shoveling other chemicals down their throats for decades. Thankfully the piggies keep eating all their comfort and fast food. They'll of course keep good statistics of what all those compounds do to the population. With that they'll refine their parameters and make even more addictive compounds to add to the food. Good little piggies.     I'm being sarcastic.

Okay. America seems more like a social experiment than a country
