David Angell, Emmy-winning co-creator of the hit sitcoms “Frasier” and “Wings,” and his wife, Lynn, were among the 266 people killed aboard the four commercial planes that were hijacked in Tuesday’s attacks on America. According to Variety and the Hollywood Reporter, the two were aboard a flight from Boston to L.A., one of the two hijacked passenger aircraft that smashed into the Manhattan’s World Trade Center shortly after 9 a.m. The Angells had been attending a family wedding on Cape Cod in Massachusetts and were returning home on the doomed flight. Besides words of condolences from NBC and Paramount (which produced many of Angell’s shows), a statement was also issued from the Roman Catholic diocese in Burlington, Vt., where David Angell’s brother is bishop. “Bishop Angell first learned that his loved ones were listed as passengers on the hijacked American Airlines flight after completing a special noon Mass for the victims and their families of the attack,” it said. Also onboard that plane, actress and photographer Berry Berenson, 53, of Los Angeles. Berenson was the widow of the late actor Anthony Perkins, who died in 1996 at the age of 60, and the mother of their two sons, Osgood, 23, and Elvis, 19. Her sister is actress Marisa Berenson (“Cabaret”).
