Hmm. Just had a thought: presumably the tapes of Doctor Who
were erased so that they could be taped over with new programs. Is there any way to determine what new programs were recorded onto those specific tapes, and whether the actual physical tapes themselves still survive? I'm thinking that at least some bits of the original data may still be there, like a palimpsest
, and maybe there's a way that modern technology could digitally extract those fragments of information and reconstruct the original images, similarly to how the Reconstruction Team was able to discover fragments of color data on black-and-white copies of some of the episodes and use them to recreate the lost color information. But first they'd have to identify the actual physical reels of tape that used
to have the Doctor Who
episodes on them.
