RE: SUSPECT POSSIBLY HIDING ABOARD AIRCRAFT

---

[redacted], Novato, California, [redacted] no home phone but can be reached through [redacted] phone [redacted] or an answering service [redacted] appeared at the San Francisco Office on 11/19/73, and advised as follows:

Since he had seen the movie "Airport" on television he has given a great deal of thought to how this crime was perpetrated. He stated that he was principally interested in obtaining any reward that might be forthcoming for furnishing information concerning this case. He also stated that he had formerly worked on airplanes and was familiar with them; however, he did not know the difference between a Boeing 727 and a 737.

particular aircraft. According to [REDACTED] any competent mechanic, if given enough time, could remove panels from the airplane either in the floor or restroom area, secrete himself in the space after fashioning some kind of device to pull the panel or floor in behind him. He suggested that the hijacker could have gotten into the cargo area and hidden in a box in the above manner. [REDACTED] theory was that a mechanic with the airline could have accomplished these things at any time when the aircraft was having a major overhaul.

It should be pointed out that in all probability the hijacker jumped from the airplane since there was evidence of a pressure change when the stairwell closed apparently after a heavy object jumped from the stairs. The same pressure change occurred when a subsequent demonstration was conducted by throwing a 150 pound object from the stairs.

LEADS:

MINNEAPOLIS

AT MINNEAPOLIS, MINNESOTA. 1. Ascertain from Northwest officials if it would be feasible to accomplish the above and if engineers of the company could be consulted to either confirm or reject the idea.

2. If deemed necessary, locate and examine the aircraft for any evidence of tampering with panels, floors, etc.
