Review of Roswell: The First Witness

I liked that Ben Smith dove deep interviewing so many relatives and using so many experts... But I kept feeling that some important things were left out. I would have liked to have seen research into Jim Marrs' Alien Agenda which was greatly researched and referenced and would have perhaps provided many more leads. I would also like to know more about the 1949 Roswell crash which produced a surviver that lived until 1952. On a further tangent, I wonder if Ben Smith is aware of the intended 10 year exchange with 14 American astronauts who traveled to Serpo. In fact they lost track of time and didn't return for 14 years... and only 10 of them came back, as 2 were deceased and 2 elected to stay.
