United Airlines and its 5,000 striking pilots are settling in for the possibility of a long walkout now that contract talks have broken off and no new talks are scheduled, spokesmen for both sides said in Chicago. “I think we’re prepared to hold out as long as we have to,” said Dale Richter, a 17-year United employee and spokesman for the striking Air Line Pilots Assn. “The morale is very high.” Said United spokeswoman Eileen Golab: “We have no idea (how long the strike might last) at this point.”
