This is a great story in-and-of itself. These individuals worked hard, when the relevant institutions did not care, and protected something of historic value. The famous "Earthrise" photo alone is of great value. Who knows what is on the other tapes?
And this brings up another important concern: how much valuable, important data do we have stored on media that we may not be able to read? These old tapes required work old tape drives to read them. How long before CD's and DVD's face the same problem?
And what do you use to backup your files?
