You can see the thing (doesn't look huge) that flew in during second 4 in Noel Report's video. Here's its approach path:

500 kg

To me the attacking flying object in the video seems to be too slow for a glide bomb, it's path is not straight enough for such speeds. It's more likely a big drone. A package of 30 kg explosives can be enough to weaken the already damaged structure of the building to the point of fatal failure.

Oof, you're way off.

Have you ever worked professionally with explosives on any structure of that size?

It's not a drone. It pierced the first wall. It's a 500 kg glidebomb.

It didn't pierce any wall, it went through a big opening there 👀 (not an original door or window, LOL). No need for a huge amount of explosives when applied at the right spot. I know because I've done for some years the math for those guys who demolish big buildings in city centers for a living.

Dude you're talking artillery shell explosive weight. This here is an aviation bomb. You're an order of magnitude off. You can stop talking now, we already know the answer.

The right amunt of ecploseives deliver to the right spot is always doing the same work. And now lean back, you sofa expert.

Maybe if you drill all the holes in all right places you can get away with 30 kg, but that's obviously not what this is. Stop emberrassing yourself.

A drone could never take down a building of that size..just as a drone cant take out the Kerch Bridge. Even a well place drone would do nothing to take down a large building. You would need dozens of charges placed on all the supports.. or a very large glide bomb as was used here. Most likely a FAB.

You were exactly right about the flightpath though. But it's most certainly at least 10 times as many explosives. Exactly like a 500 kg glidebomb.

Definitely not a drone. Clearly a glide bomb from the image. You can even see the wings of the glide bomb expand as its dropped.. thus the reason its called a glide bomb.

Maybe more like 500 or 1000. Those buildings are kinda big.
