I agree with you that taxpayer dollars should not be spent on an investigation of seven astronauts when a more gargantuan loss of life occurred on 9/11 and no serious investigation was ever carried out. The investigations conducted by our government were an absolute joke. In fact, they did a lot to destroy crucial crime scene evidence by hauling off all the wreckage from the World Trade Center recovered from Ground Zero to India and China and having it melted down! It should have been stored somewhere for more forensic analysis, but the 'powers that be' were very scared of the possibility that their evil deeds would be exposed!!
By the way, the space agency, NASA, is owned and controlled by the Illuminati elite. Take a look at their logos - it is filled with occult Masonic and Illuminati symbolism. Therefore, anything coming from this agency and any of their efforts are highly suspicious in my book. I have to doubt the sincerity of their investigation behind the deaths of those astronauts. But that's a different story.
