CBS is pulling the repeat of its movie “Final Descent” this Sunday because of the Wednesday night crash of Swissair flight 111.“Final Descent,” an action-adventure thriller starring Robert Urich and Annette O’Toole, is about a jumbo jet that can’t land after a mid-air collision with a prop plane. The original broadcast generated a 12.9 rating and 21 share. CBS felt it was insensitive to air the film so soon after a plane crash. Instead, CBS will air a repeat of the film “It Could Happen to You” on Sunday. That film’s original broadcast rated a 14.0/23, the highest rating for a theatrical airing on any network last season.
