On August 30, A Moderna Truck Crashed. Airspace was shutdown, Hazmat dispatched, DOD took over, and IIRC the public was not allowed near the incident.
But why shutdown the airspace and keep people away? Why was Hazmat necessary? The answer is most likely they didn't want people to see "something". And that "something" would be visible from airspace. And that "something" required hazmat suits.
Of course this is just a theory, but the piece that makes all this fit together is that they were gassing/fogging the area. Remember when they were wearing hazmat suits and fogging the streets in China at the beginning of the pandemic? This is too similar. If fogging fixes the problem, then they were killing something that was released by the vaccine. Virus? Bacteria? Parasites? I'm not sure.
Maybe the actual aerial infection rate is deadly but doesn't last long however based on the amount of doses/concentration it last longer. So let's just say people dropping dead in China was legit, maybe that happened because the concentration of the virus was so high that it just shut down the person's entire bodily functions.
Could be why they didn't want anyone close, cause if just 1 person got a picture of a body on the floor with no physical abnormalities it might of gotten people talking about the origin of the virus.
