[redacted], Northwest Flight Dispatch Center, called twice on the afternoon of November 28, 1971. The first time he advised that he had checked on possible information and believed that a more accurate pin-pointing of the possible place of descent of the hijacker would be three statute miles east northeast of LaCenter, Washington, on a bearing of 080 degrees, true. He said the center of the circle would depend on the clock being a few seconds off one way or the other or the Unsub falling free before he opened the chute. However, he would estimate that a circle with a three-mile radius from the point described above should come close to the place of descent.
He called back subsequently and said that he had talked to the man who was working the radar at Portland which was very accurate since it was very close to the plane at the time and determined that the plane was actually one to two miles east of the center of this particular fly-way. He said for this reason, we might consider moving the center of the circle described above one or two miles due east.
This information was furnished to SA MANNING on November 28, 1971. He was instructed to make certain that this area was thoroughly searched and to consider air coverage on November 29, 1971.
