Re: SEARCH AREA
---
On 1/10/72 after having received the new plotting of the search area, prepared by [REDACTED], the writer telephonically contacted [REDACTED] at Northwest Airlines, Minneapolis.
[REDACTED] advised that his computations based on the results of the experimental flight on 1/6/72, coupled with updated information furnished by [REDACTED] of the U.S. Air Force at McChord AFB, he had prepared a revised plotting of the course of the aircraft as well as a probable jump area.
A memo prepared by [REDACTED] as well as a map which he also had prepared, had been received and during the telephone conversation [REDACTED] advised that in his judgment, the best possible spot to search for the subject would be at Point A and proceeding from there to Point B on the map. [REDACTED] memo adequately explains the lines drawn on the map and are therefore not further being explained.
[REDACTED] said he feels that the hijacker is more apt to be found south of line A & B than north of the line and more apt to be in the western part of the possible area than in the eastern part.
As a result of talking with [REDACTED] the writer drew arc's emanating from Point A down to a point on line G thru K. The arc's were extended along the lines A-B and down to the same aforementioned line G-K. It was his feeling that this would be the most fruitful area.
The next choice would be a continuation of the arc's to the north of line A-B also to line G thru K.
The arc's drawn on the southern portion from lines A-B are in solid felt marker pen and the ones above are in a dotted arc. CEF:klb (4)
