Detroit A strong odor Friday morning has forced the diversion of a Delta Airlines flight that was headed from Frankfurt, Germany, to Detroit Metropolitan Airport.

According to Delta, flight 143 made an unscheduled landing at Dublin International Airport out of an abundance of caution to examine the source of an odor in the aircraft.

The flight landed without incident and passengers deplaned normally while the source of the odor was investigated. According to Delta, an alternate aircraft was made available to the passengers.
