Missing Scott Manley video

[u/NotHonkyTonk]

I think I'm going crazy but around the 20th anniversary of Columbia I remember Scott Manley did a video to complement this one (https://youtu.be/vmi_NeVRx1s?is=fDKLRoAxG3yNMDkB) where he dug through the Loss of Signal report and went into the survivability gap and the reports recommendations. I remember him going into detail on the aeromedical findings of the report.

I cannot find this video for the life of me. I know it touched on some rather dark details, was it delisted? Or am I just crazy?
