PiS simply rejected three official reports and started a classic Gish gallop, spinning not a single but dozens of half-baked conspiracy theories, and at all the time completely ignoring the primary and fundamental questions: why did the crew simply fly into the ground while talking and ignoring TAWS warnings?
All alternative theories simply pretended none of this ever happened - the plane was lured into an artificial fog, blown up etc etc, as if the cabin recordings never existed.
