Passengers on a Singapore Airlines flight were left surrounded by a chaotic mess after their flight fell 20 metres when it hit severe turbulence.

A total of 11 passengers and one crew member were injured on flight SQ308 from Singapore to London last Sunday.

One passenger on the flight, who saw his coffee end up on the ceiling, managed to take pictures of the destruction which he posted to Instagram.

Alan Cross told ABC News that passengers had been warned to expect turbulence and that the breakfast service would be temporarily suspended.

A short while after the seat belt sign came on, the captain issued an abrupt order for all flight attendants to take their seats immediately.

Alan Cross said the subsequent turbulence felt “like being in an elevator with a cut cable or free-falling from some amusement park ride”.

He said everything that was not tied down, including people, hit the ceiling.

The airline told The Australian: “Eleven passengers and one crew member sustained minor injuries when the aircraft experienced a sudden loss of altitude and were attended to by medical personnel on arrival at Heathrow Airport. Seat-belt signs were on at the time and meal services had already been suspended.”

Within just an hour, the carnage had been almost completely tidied up and the plane was practically back to normal.

Alan Cross said: “The cabin crew was amazing in the aftermath, as were fellow passengers who helped everyone around them then in a calm and efficient clean-up.”

He said crew checked for injuries before cleaning up the mess and gave passengers boxes of chocolates as they departed at Heathrow, where they were met by paramedics.

The vast majority of passengers are not affected by turbulence on anything like this scale, but some research suggests that unsettled flights could become the norm thanks to global warming.

Earlier this year scientists claimed climate change could result in flights from London to New York getting much bumpier in the future.

Researchers from East Anglia and Reading universities analyzed supercomputer simulations of the atmospheric jet stream over the North Atlantic, concluding that climate change will increase air turbulence.

They found the chances of hitting significant turbulence will rise by 40 to 170% by 2050, with the likeliest outcome being a doubling of the airspace containing significant turbulence at any time.

Dr. Paul Williams from the University of Reading and the University of East Anglia’s Dr. Manoj Joshi said the average strength of turbulence will also increase, by between 10 and 40%.

He said: “Most air passengers will have experienced the uncomfortable feeling of mid-flight air turbulence. Our research suggests that we’ll be seeing the <<fasten seatbelts>> sign turned on more often in the decades ahead.”

British researchers have explained the way cancers make a chaotic mess of their genetic code in order to thrive.

Cancer cells can differ hugely within a tumor – it helps them develop ways to resist drugs and spread round the body.

A study in the journal Nature showed cells that used up their raw materials became “stressed” and made mistakes copying their genetic code.

Scientists said supplying the cancer with more fuel to grow may actually make it less dangerous.

Most normal cells in the human body contain 46 chromosomes, or bundles of genetic code. However, some cancerous cells can have more than 100 chromosomes.

And the pattern is inconsistent – pick a bunch of neighboring cells and they could each have different chromosome counts.

This diversity helps tumors adapt to become untreatable and colonize new parts of the body. Devising ways of preventing a cancer from becoming diverse is a growing field of research.

Scientists at the Cancer Research UK London Research Institute and the University College London Cancer Institute have been trying to crack how cancers become so diverse in the first place.

It had been thought that when a cancer cell split to create two new cells, the chromosomes were not split evenly between the two.

However, lead researcher Prof. Charles Swanton’s tests on bowel cancer showed “very little evidence” that was the case.

Instead the study showed the problem came from making copies of the cancer’s genetic code.

Cancers are driven to make copies of themselves, however, if cancerous cells run out of the building blocks of their DNA they develop “DNA replication stress”.

The study showed the stress led to errors and tumor diversity.

Prof. Charles Swanton said: “It is like constructing a building without enough bricks or cement for the foundations.

“However, if you can provide the building blocks of DNA you can reduce the replication stress to limit the diversity in tumors, which could be therapeutic.”

He admitted that it “just seems wrong” that providing the fuel for a cancer to grow could be therapeutic.

However, he said this proved that replication stress was the problem and that new tools could be developed to tackle it.

Future studies will investigate whether the same stress causes diversity in other types of tumor.

The research team identified three genes often lost in diverse bowel cancer cells, which were critical for the cancer suffering from DNA replication stress. All were located on one region of chromosome 18.
