Frasier was like the Energizer bunny of television shows. The darn thing wouldn’t go away; it just kept running and running. Entering the show's ninth season, the Frasier staff was rocked by personal tragedy when David Angell, the series' executive producer and co-creator was killed on American Airlines flight 11, which struck the World Trade Center on September 11, 2001. Just two weeks later on September 25 2001, Frasier began its new year on NBC.
