Let's go! What happened to the evidence from Smolensk? 2nd part of the conversation with Prof. Wiesław Binenda

Prof. Binienda talks about moving large fragments of the wreckage, differences visible on satellite images, recording TAWS and GPS signal. He claims that part of the data has been manipulated and that a peculiar importance is attributed to an analog recording device that has not been found despite the preservation of its location.
The prof. besides talks about his attitude towards records from black boxes previously in Russian hands, the reaction of the technological community to his publications and the request for further investigation on Smolensk by younger scientists.
