A Southwest Airline flying to Dallas, Texas, from Seattle had to turn around after crew realized someone had forgotten to unload a human heart.
The captain said the heart should have been left in Seattle and taken to a hospital, according to Yahoo News UK.
The life-critical cargo shipment was reportedly unloaded after the aircraft landed.
Dan Landson, Southwest spokesperson, said the return to Seattle 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.”
The flight took off again after a five-hour delay, Landson was also quoted to have said.
