Southwest Airlines flight U-turns after human heart discovery

(FASTNEWS|COLOMBO) – A US passenger plane travelling from Seattle to Dallas was forced to turn back hours into its flight because a human heart had been left on board.

Southwest Airlines says the organ was flown to Seattle from California, where it was to be processed at a hospital to have a valve recovered for future use.

But it was never unloaded and its absence was not noticed until the plane was almost half-way to Dallas.

The heart itself had not been intended for a specific patient.

Details of the incident, which occurred on Sunday, were revealed in media reports on Thursday.
