Not your typical "conventional explosives." Nano-thermite explosives were used by the CIA to bring those towers down by acting like a cutting torch through that steel in structural locations. The core was collapsed first and then the core pulled down the sides of the building. 3/4 inch steel plate steel is extremely strong and takes extreme temperatures to cut through it. Jet fuel fire is not going to do it. During the asbestos abatement program when the the towers were shut down is when the explosives were placed. WTC 7
I believe directed energy weapons exist and are used in California to set people's houses ablaze, but those towers were rigged with explosives. They came down in a perfect pattern of collapsing within their own footprint; exactly like buildings rigged for demolition do.
THD is scared to death of the CDC. They're scared that the CDC is going to slap them with heavy fines unless the corporation forces their employees to follow CDC guidelines. Masks whenever you're inside the store. Masks whenever you're closer that 6 feet to the customer. And now as of Monday, even the vaccinated have to wear masks.
Not yet. Not until the nanobots build the computer inside the vaccinated person's brain.
