I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Airport Movie plot: The story takes place during one long night during a sudden blizzard at Lincoln International, a fictional Chicago airport based very loosely on O'Hare International Airport.The action mainly centers on Mel Bakersfeld (Burt Lancaster), the airport general manager. His devotion to his job is tearing apart his family and his marriage to his constantly angry and domineering wife Cindy (Dana Wynter), who resents his use of his job at the airport as a device to avoid going to various after-hours events she wants him to participate in, as she attempts to climb into the social circles of Chicago's elite. His problems in his marriage are further exacerbated by his romantically-charged friendship with a lovely divorcee, Trans America Airlines (TGA) passenger relations manager Tanya Livingston (Jean Sebrig).The movie centers on Bakersfeld's struggles to keep the airport open during the snowstorm. His chief problem is the unexpected closure of primary Runway two zero, caused when a landing airliner turns off past the wrong side of a runway marker light, burying the plane's landing gear in the snow, and blocking the runway. Bakersfield is forced to call upon Joe Patroni (George Kennedy), the tough and practical head of maintenance operations for Trans World Airlines, at Lincoln. Patroni is told to move the disabled aircraft blocking the runway two zero. Patroni spends the rest of the movie with his men to dig the plane out of the snow and fights with the pilots to do so under the aircraft's own power without damaging it.Meanwhile, Bakersfield deals with his brother-in-law Vern Demerest (Dean Martin), a pompous and self-confident senior pilot for Trans America Airlines who opposes Bakersfield on a number of issues involving business and personal issues. Both Mel Bakersfield and his sister Sarah (Barbara Hale) are unaware that Vern is having an extramarial affair with Gwen Meighen (Jacqueline Bisset), a chief stewardess on his routine flights whom is planning her latest trip to Rome, Italy and is frustrated about her... My question: Who is pregnant?
A:
Gwen Meighen
