Currently only 19 complete serials survive, all from reel-to-reel off-air recordings made by John Wright in 1972. Also, the first three episodes of a remake of "Escape in Time" currently exist. Episodes 1 and 2 are copies from the original Sonovision tapes, and episode 3 is from an off-air recording, on audio cassette, made by Barbara Peterson; the rest of this serial is still missing. These episodes are also known to have been transmitted in New York on station WBAI on 99.5 FM, from 1977 to the early 1990s, and are currently being transmitted on Miami station WRGP on early Monday mornings.
