Here’s a really interesting article on the possibility of finally finding out what was said during the infamous 18.5-minute gap on Richard Nixon’s “Watergate Tapes.”
Many have since tried to figure out what transpired during that gap. But now, Phil Mellinger, a one-time systems analyst at the National Security Agency (NSA) who went on to a career in high-tech corporate security, thinks he has discovered a way to determine what was wiped off the tape. And the National Archives believes he’s on to something. In response to a request from Mellinger, the Archives unit in charge of the Watergate files has proposed conducting a scientific test that could yield information on what was said during the missing minutes. This procedure would not, as has been tried unsuccessfully in the past, seek to recover the obliterated audio. Mellinger’s approach takes a simpler route: resurrecting Haldeman’s notes via a CSI-ish technology that can extract information from the imprints made by a ballpoint pen.
