No, it’s not true. You wouldn’t ever use magnesium for that anyways, you’d use an actual demolition charge if you were dumb enough to rig every tall building with explosives. But no, nobody is that dumb - the kernel of truth at the heart of that one is that some large buildings have demolition plans drawn up when they’re constructed (important note: the WTC didn’t have that, it’s both very rare to do and a much more modern practice than the WTC buildings), which are just a reference for if/when the building is demo’d in the future. They’re not rigged to blow, though. Hell, aside from all the obvious reasons you wouldn’t do that, chemically most explosives would become uselessly unpredictable after being strapped onto a building for that long. Just an absurd idea.

Since we’re all fighting about it, the version of WTC 7 I heard:
Buildings above a certain height tend to have magnesium charges installed, so that in the even of catastrophe (like say two hijacked airplanes), they can be brought down in a controlled manner with as little collateral as possible. I’ve heard WTC 7 was accidentally wired up alongside the twin towers, so when the call was made, it came down as well.
Is that true? No fucking clue.

Like a system like the swiss bridges? They have marked points but don’t just leave the charges on the bridge. It flies in the face of conventional engineering to plan a failure point on something that should never fail. So all building are wired to go at any moment? You would think there would be a few more accidents and this would require a large and obvious agency to manage and monitor in secret. Considering how much demolition work costs it is not “easy” to bring a building down.

No, Building 7 was just poorly designed. They built a 40+ story building on a doundation meant for 25 stories, it’s surprising it lasted as long as it did.
