I’m polish so i can give a proper summary of that theory Gonzalo put out in this video. First, it wasn’t a farmer who posted photos of this S-300 fragments, but a firefighter who first came to that area in order to save people. Literally moments later a whole swarm of military vehicles came to that area and shoved everyone out, collected all the evidence and pieces of the rocket and drove away, never to be seen again. Even today, polish government STILL gave no evidence, police keeps journalist out of the area and “lying Pinocchio” polish prime minister and “Jewlensky” still claim that it was russian doing, so if not for these photos, whole world would have be none the wiser. Second thing, it wasn’t a “fertilizer” facility, but a small corn grain warehouse and distribution centre, that’s a place where farmers come in order to sell their product,. Bombing this place wouldn’t create an explosion like in Lebanon, but corn get’s hot during storage, like rly hot, corn dust is quite dangerous, so those old S-300 ukrainian rockets could go crazy after missing their target and keep flying until they find a new one with their heat-seeking sensors.
