Ben Smith and Jesse Marcel's grandson, Jesse III, visit Jennifer Naso, one of America's top document experts, to see if she can help verify that the handwriting in the journal belonged to Major Jesse A Marcel, thereby authenticating the journal. Smith then heads to Arlington, Texas, to magnify and inspect a crucial photo taken at the Army press conference in 1947 where the US military claimed that what Marcel had originally identified as a flying saucer was in fact a weather balloon.
