This is the video that shows the trailer of liquid left on the floor after a passenger suffered explosive diarrhoea by making a dash for the toilets.

The stench was apparently so bad the pilot declared it a “biohazard” and the plane that was travelling between Atlanta and Barcelona on 1st September was forced to turn around and head back to the US for a clean-up.

The footage that was shared by an X (formerly Twitter) user named “Xansby Swanson” shows a long trail of brown material on the floor which was reportedly liquid faeces.

In the message he wrote that he had been sent the images by his little brother who had been on board and said: “Haven’t laughed harder than his phone call to me at midnight to explain why he was still in America.

“He said it was the funniest thing he’s ever experienced.”

Other passengers however had apparently not seen the funny side of the incident.

The cabin crew appear to have tried to cover it up with paper towels in order to help people navigate their way out of the plane but the towels seem to have run out before they managed to complete the job.

A Delta Airlines spokesman said 336 passengers were delayed for a few hours as a result of the biohazard incident.

After disembarking cleanup crews scrubbed the jet and replaced the sodden carpets in a five-hour operation with the flight eventually landing after an eight-hour delay.

Air traffic control audio recordings reveal the pilot explaining the reason for the turnaround saying “Divert to ATL – passenger diarrhea all over aircraft – biohazard.”

While they turned the pilot confirmed the situation saying: ‘It’s just a biohazard issue, we had a passenger who had diarrhea all the way through the airplane so they want us to come back to Atlanta.”
