 ```Greetings, bbush! I love these kinds of problems, and used to work them frequently when I was younger. To keep everything straight, it's easier to draw a grid, starting with the initial information: Passengers Borough Profession or other Characteristic ------------------------------------------------------------ Smith Johnson deaf-mute Cohen Bronx Crew Borough Flight Position ------------------------------------------------------------ Smythe not the Co-Pilot Jensen Kohen Then, we'll try to fill out the blanks using deductive reasoning. The passenger whose name sounds like the navigator's lives in the Bronx. Since passenger Cohen lives in the Bronx, Kohen must be the Navigator, who lives in Manhattan. If Smythe (who had a fling with the Co-Pilot's wife) is not the Co-Pilot and not the Navigator (Kohen is the Navigator), Smythe must be the Pilot. Since Kohen the Navigator lives in Manhattan, Kohen's neighbor the passenger must live in Manhattan, too -- so the neighbor is *not* Cohen, who lives in the Bronx. Since that neighber is a famous opera singer, they can't be deaf-mute, either, so that neighbor in Manhattan can not be Johnson -- thus, they must be Smith. That leaves Johnson in Brooklyn. Passengers Borough Profession or other Characteristic ------------------------------------------------------------ Smith Manhattan famous opera singer Johnson Brooklyn deaf-mute Cohen Bronx Crew Borough Flight Position ------------------------------------------------------------ Smythe Pilot Jensen Co-Pilot Kohen Manhattan Navigator Usually, in these problems, enough clues are given to enable all of the blanks to be filled in. However, in this case, we are not given enough information to determine Cohen's profession, or in which New York City Boroughs Smythe and Jensen live. However, we do know the positions of the flight crew: Smythe Pilot Jensen Co-Pilot Kohen Navigator Thanks for posting a fun brain-teaser! Regards, aceresearcher```

 ```I came up with a different answer. Cohen (passenger) is said to live in the Bronx (fact a). The passenger who's name sounds like the Navigator lives in the Bronx (fact d). Since Cohen lives in the Bronx I would then Kohen is the navigator. Otherwise Johnson would live in the Bronx.```
