SEATTLE (AP) — A Boeing 757 operated by Delta Air Lines flying to Seattle from Atlanta made an emergency landing after the flight crew noticed an indicator warning of a possible problem with one of its engines. The Seattle Times reports a company statement says Delta flight 2123 was diverted Monday to Salt Lake City “out of an abundance of caution.” The plane landed and fire crews at the airport said the engine did not appear to be damaged. The 16-year-old jetliner was powered by Pratt & Whitney engines, the same manufacturer behind two Saturday engine failures on Boeing planes. Boeing declined to respond to questions from the newspaper.
