Quote from The Moscow Times here."We are not contending that they did not fly [to the moon], and simply made a film about it. But all of these scientific — or perhaps cultural — artifacts are part of the legacy of humanity, and their disappearance without a trace is our common loss. An investigation will reveal what happened," Markin wrote.
An international investigation could help solve the mystery of the disappearance of film footage from the original moon landing in 1969, or explain where the nearly 400 kilograms of lunar rock reportedly obtained during several such missions between 1969 and 1972 have been spirited away to, Markin suggested.
