Re memo of SA THOMAS J. MANNING to SAC, 10/19/72

---

On 10/20/72 SA [REDACTED] contacted [REDACTED] Washington and he furnished the following information:

He lives directly under the fly way between Portland and Seattle. He recalls that the night of the hijacking a plane was flying very low and slowly over his house in the early evening and about 5 minutes after the plane flew over he heard on television that the hijacking was in progress. He stated the plane was a jet airliner but he did not see the plane. It was about 4 to 5,000 feet from the ground and he recalled that the weather was overcast, very low clouds and it was raining. The flight of the plane was about 20 miles from Mt. St. Helens

He pointed out that planes on the fly way always fly about 10 to $2,000 feet and in the four years he has lived at his present location he has never heard one so low as on the night of the hijacking. He advised that he knows the plane was over 3,000 feet for he lives near Mount Tum Tum and that is 3,000 feet and the plane was above that mountain. He also pointed out that the east end of Lake Merwin is approximately [REDACTED] He pointed out that the plane flew directly over [REDACTED] area and the area over which it flew is extremely rugged terrain. He pointed out that recently there have been a number of hunters in that area, from Lake Merwin to [REDACTED] area.

[REDACTED] stated he feels that if it was the hijacked plane then the area which has been searched would have been too far west. He pointed out that the plane was heard before 10:00 PM and after dark but he could not fix the exact time he heard the plane fly over.

[REDACTED] furnished a copy of a map on which he drew what he felt was the flight of the plane and this map is attached.

The area over which the plane flew has a number of private owners but the majority of the area is owned by Gifford Pinchot National Forest and the Weyerhaeuser company.
