The transcription of conversation number 342-16 in the public archives of the White House tape recordings between President Richard Nixon and his Chief of Staff H.R. Haldeman documents only the 18 1/2 minute silence on this mysteriously erased tape. There is no reference to any conversation before or after the erasure. Audio specialists hope, one day, to electronically recover the conversation from the master tapes. The B-roll style production footage conspires to reconstruct a space between concealment and revelation, silence and speech.
