Werlich Overlay Map
This is a copy of Werlich’s Overlay Map (transparency) that is included in the Project Blue Book file for the 24 October 1968 Minot case. Due to security restrictions in forwarding the original classified 200-series map chart (1:200,000), Col. Werlich provided this overlay with pertinent information regarding the UFO events, and suggested that Blue Book staff acquire the original (underlay) map at Wright-Patterson AFB, Ohio (Memo, 1 Nov. 68a, 4, 6). It is not known whether Blue Book staff acquired the master chart, since the case file contains the Off-Base Disaster Control Grid Map (1:250,000).
