Delta Airlines flight 2116 had to return and make an emergency landing at Los Angeles International Airport, California, shortly after 9:30 a.m. on January 13.

The Boeing 757 took off for Minneapolis at about 8:30 a.m. but had to turn back shortly afterwards due to a mechanical issue.

The plane landed safely after shedding off extra fuel. All 146 passengers and 6 crew members aboard remained unharmed.

The airline later said in a statement, “The crew of Delta flight 2116 from Los Angeles to Minneapolis/St. Paul followed procedures to return to Los Angeles International after a potential systems issue was observed. The aircraft landed safely without incident and taxied to the gate under its own power. Delta is currently working to accommodate customers while technicians examine the aircraft. Safety is always Delta’s top priority and apologizes to customers for the inconvenience.”
