Ive heard of Donald H. Menzel, the Astronomy dean at #Harvard destroying thousands of photo plates.
I did not realise it was actually called "Menzel Gap"!!!
Dr Menzel was a #UFO debunker, having written THREE books debunking #UAP (https://en.wikipedia.org/wiki/Donald_Howard_Menzel)
This is consistent with the narrative that there is actually a group of non-state actor individuals within the US that dedicated their lives to keeping #NHI reality secret because of multiple reasons (Mainly to do with money and religion, of course).
Question remains: What UFO evidence was on those plates that made Menzel destroy all those plates.
