What you are hearing
This is not a reenactment.
Every voice on Signal Unknown was recorded in the 1960s and early 1970s. The Apollo 8 flight tapes are airing now as regular programming, with Apollo 11, 12 and 13 to come. The voices are unedited; only the dead air between transmissions has been trimmed out.
