According to McBeth, the crater means at least a 400 kg warhead. That is cruise missile size, not surface to air missile size.
There are hundreds of detonated S-300s littering Ukraine. There is only one 400 kg high explosive sized crater in Poland.
What do you mean by mislabeled? A stock photo uploaded to illustrate the event? I have seen several photos already and they all show the same parts. Regarding the crater how do you know? It definitely doesn’t look like produced by a cruise missile. 400 kg of TNT is a big boom. False flag plain and simple. Not the first one.
S-300 missiles are big...some of them have more HE than a 500 pound GP bomb. If the ground is soft, then a 500 pound GP bomb could make a crater the size in the picture.
Analysis by picture is sketchy at best.
Assuming it was an S-300 missile, then what I can't understand is why it didn't self destruct when it lost track on the target.
If it was an S-300 missile, then it is most certainly Ukrainian since the missiles don't have the range to fly from eastern Ukraine to Poland.
