I was saddened to hear about this last night on Ian Punnett's stint on Coast to Coast. He had Georgio Tsoukalos on to discuss it as he was a personal friend of Coppens for many years. Sounds like his cancer, angio sarcoma?, is incredibly rare - only 10 in the US per year, and moved very fast. As this is a conspiracy site, I can't help but wonder if he riled someone. I heard him recently - I think on the Paracast - and he was a great guest. Intelligent and very reasonable sounding. It's a shame such a young man would pass away and also one who was doing such great work in his area. Why is he dead and George H.W. Bush and Kissinger still alive? This is a great mystery of life to me.
