A Singapore Airlines spokesman later revealed that there is not enough evidence that suggested the livestock were responsible for the sudden landing.
A few gassy goats ended up causing a minor emergency onboard an airplane a few years ago. It was reported that the Singapore Airlines Boeing 747-400 freighter plane was forced to make an emergency landing after the flatulence of 2,186 animals in the cargo hold set off smoke alarms. The plane left from Adelaide, Australia, and was supposed to go to Kuala Lumpur in Malaysia, however, the inconvenience caused them to divert their route to Bali's capital, Denpasar, on October 26, 2015. According to Daily Mail, the aircraft landed following an urgent announcement and emergency services were quick to board it in the hopes of investigating the matter.
On entering the space which was carrying four crew members and the flock of goats, they were surprised to find no trace of fire, heat, or smoke. Per the Aviation Herald, the smoke indication alarm was set off due to the exhaust gasses and manure produced by the animals on board the flight. After a two and a half hour pitstop, flight SQ-7108 set off to reach its destination. "On 26 October 2015, a Singapore Airlines Cargo Boeing 747 freighter aircraft carrying a shipment of goats, operating as SQ7108 from Adelaide to Kuala Lumpur diverted to Bali after the crew received a warning from the onboard fire alarm system," said a Singapore Airlines (SIA) spokesman.

"The aircraft landed at 5:11 pm local time and upon inspection, no evidence of fire or smoke was found. The aircraft was certified serviceable and departed at 8:20 pm local time. It delivered its shipment safety to its destination in Kuala Lumpur at 11:16 pm local time," the spokesman continued. However, Huff Post reported that the Singapore Airlines spokesman refuted the claims of the flight making an emergency landing due to gas and manure. He explained that the claims could not be confirmed. "Inspections were carried out on the ground and the aircraft was certified serviceable," he said.

A Singapore Airlines spokesman later told the Singaporean newspaper Today that there was not enough evidence that suggested the gassy livestock were responsible for the sudden landing. "That is an assumption being made by media, which we are unable to confirm." However, the founder of The Aviation Herald Simon Hradecky stood by his report about the cause saying that they got their information directly from an official report from Bali’s Denpasar Airport. He also noted that the Tribun Bali had reported the same thing they did.
"I am aware that [Singapore Airlines] are disputing our coverage. Fact is, that emergency services and maintenance at Denpasar decided this was the cause," noted Hradecky. "Had the cause been different the aircraft would not have been able to depart again after just two hours." It must be noted that Aviation Herald's report stated the cargo had a flock of sheep instead of goats. This incident took place after another emergency landing made by Singapore Airline in August of the same year. One of its aircraft had accidentally run into a flock of storks that ended up tearing a hole in its nose. The Singapore-bound Boeing 777-200, according to Daily Mail, had left from Istanbul Ataturk Airport with 255 passengers and 14 crew members.
As the aircraft was gaining altitude, the flock of birds ended up damaging the radome, which is a weatherproof protective shield for the radar antenna. The impact also damaged other parts of the plane, including the engine on its left side. Thus, the plane had to make an emergency landing an hour and ten minutes after take off. "In three-quarters of cases of bird strike inflicts no serious damage on the plane although it's always fatal for the bird. Obviously a flock of storks which is a much larger than average bird is another matter," said an airport spokesman.
