According to reports, the aircraft was carrying over 2,000 sheep in its cargo.
A flight of Singapore Airlines traveling to Kuala Lumpur, Malaysia, had to make an emergency landing because of a rather unusual reason - sheep farts, according to Aviation Herald. The Boeing 747-400 originating from Adelaide, Australia, was carrying a cargo of 2,186 sheep when the crew thought a cloud of smoke was billowing from the plane and landed at Bali's Denpasar airport. But while emergency services did not find any traces of fire or heat after an inspection, there were traces of flammable fumes. The report has attributed the same to exhaust gases and manure produced from the sheep. After around 3 hours, the crew was ready to take flight and reached their destination safely. While confirming the emergency landing, Singapore Airlines officials, however, disputed the claim that excess gas from sheep was the reason for the detour.
There are, however, other reports besides the Aviation Herald that reported the same. According to Bali Tribune News, I Gusti Ngurah Ardita, Co-General Manager (GM) of Ngurah Rai Airport in Bali, confirmed the landing. Public Relations Staff of Ngurah Rai Airport, Shively, added it was due to "technical reasons." It was not clarified what this was. "After the aircraft landed, we checked the smoke billowing from the compartment of the aircraft, " said Ardita while adding that the plane's temperature indicator had turned on due to CO2 gas from excessive sheeps dung. The landing was made to cool the temperatures down inside the plane. Things could have easily escalated if this had not been done. Everything else inside the plane was normal. "So there was no fire, the air condition is normal," said Ardita.
Singapore Airline officials, however, were adamant that the landing was not due to sheep flatulence as claimed in the media reports. A spokesperson for the airlines told Daily Mail, "no evidence of fire or smoke was found" while adding they have not been able to confirm reports of sheep farts being the reason for the landing. "Inspections were carried out on the ground and the aircraft was certified serviceable," the spokesperson added. According to Singapore Today, another official said about the sheep flatulence reports: “That is an assumption being made by media, which we are unable to confirm.” While acknowledging that his website had got some facts wrong of the emergency landing, Simon Hradecky, The Aviation Herald founder, said everything else was correct, according to The Huffington Post.
He said he had got the information from an official report at Bali’s Denpasar Airport. He added, “I am aware that [Singapore Airlines] are disputing our coverage. Fact is, that emergency services and maintenance at Denpasar decided this was the cause. Had the cause been different the aircraft would not have been able to depart again after just two hours.” In similar news, there was another case of a flight having to make an emergency landing due to flatulence. However, this time it was from a human. The plane traveling from Dubai to Amsterdam had a pair of unruly passengers on board who decided not to hold back mid-air. A fight broke out between the offenders and the passengers seated nearby forcing the landing, according to Express.
In the end, 4 passengers were thrown out after the emergency landing. Two men caused the disturbance and two women were also involved in the altercation. The two women, sisters, have even sued the airlines for being made to deboard. One of them named Nora Lacchab, 25, said the experience was "humiliating." She said, “We had nothing to do with the whole disturbance. We distance ourselves from that. We had no idea who these boys were, we just had the bad luck to be in the same row and we didn’t do anything. All I will say is that the crew were really provocative and stirred things up.”
