On 11/29/71 I talked to [REDACTED b6/b7C] Northwest Airlines, Minneapolis, Minnesota.
I pointed out to him that I had examined the log of this flight very carefully and it would appear that the area in which we are currently searching is the most logical one to search. However, I was curious to know if the pilot would be able to detect a difference in the trim of the plane, caused by the added weight brought about through the hijacker's descent on the stairway.
[REDACTED b6/b7C] said this would very likely be detected by the pilot were it not for the fact that the plane was on "automatic pilot" during the flight, which he des- cribed as being a normal procedure. He continued, however, and said he had examined minutely the flight recorder record and was unable to detect any similar occurrence in the airplane at the site we are presently searching. He advised that in view of this very likely there would be no other logical place to commence a search at this time.
