What does the scan show?
A person reads every report. Corrections are made by hand, to the data — titles, dates, names, which pages belong together — never to the scans, and they can take a while to appear.

Re Bureau letter to Seattle, dated 6/8/73.
Referenced communication enclosed a letter from a [REDACTED] who has offered two possible solu- tions to captioned matter. Seattle Division's comments to the feasibility and plausibility of these solutions were requested by the Bureau.
One of the solutions was described by [REDACTED] as follows:

(1) All of the descriptions of UNSUB supplied by crew and passengers agreed for the most part, and no indication of UNSUB wearing a disguise (i.e., wig, makeup) was given.
(2) All of the statements by crew and passengers agreed for the most part as to what took place during the hijack. A conspiracy involving seven or more persons would probably have some discrepancies as to story content.
(3) The crew described a pressure oscillation which occurred at 8:11 PM on November 24, 1971. The fact that an oscillation would occur when someone parachuted from the rear air stairs was not known until January 6, 1972 (see above).
