A plane had to make a u-turn midair because someone had left a human heart on board, it has been reported.
The Southwest Airlines flight bound for Dallas, Texas, had to turn around and head back to Seattle-Tacoma International Airport after the crew realised someone had forgotten to unload the heart.
According to the Seattle Times, the captain explain that the heart should have been left in Seattle after an earlier flight from Sacramento and taken to a hospital.
After the u-turn, the flight landed in Seattle and the “life-critical cargo shipment” was unloaded.
Southwest spokesman Dan Landson told the newspaper the return to Seattle was vital because it was “absolutely necessary to deliver the shipment to its destination in the Seattle area as quickly as possible.”
He said: “Nothing is more important to us than the safety of our customers and the safe delivery of the precious cargo we transport every day.”
Once the plane was back in Seattle, passengers also had to get off because of a mechanical delay.
It took off again after a five-hour delay, Landson reportedly said.
