Singapore Airlines CEO Goh Choon Phong has offered his "deepest apologies to everyone affected" on a London to Singapore flight that encountered severe turbulence
The lone fatality has been identified as 73-year-old Geoff Kitchen, who died of a suspected heart attack
Seventy-one wounded passengers are being treated at a hospital in Bangkok, where the plane made an emergency landing. Six are in critical condition
From the Thai capital, 143 people who were uninjured were flown to Singapore overnight
Singapore's new PM Lawrence Wong has promised a "thorough investigation" into the incident
Singapore Airlines says its team has arrived in Bangkok to help its colleagues and authorities on the ground in Thailand.
"We are providing all possible assistance to the passengers and crew on board SQ321, both at the hospital and the airport," it says in a statement.
We're now hearing from aviation journalist Sally Gethin, who tells BBC Radio 5 Live it is extremely rare for someone to die due to turbulence impacting flights.
She says the Singapore Airlines incident is an example of "clear air" turbulence, where an aircraft flies into a pocket of air which isn't detected on a radar.
"Anything that isn't bolted down in a severe case of turbulence is at risk of damage or worse", she says, adding: "Wearing your seatbelt can make a difference between life and death."
As we've been reporting, severe turbulence on a Singapore Airlines flight from London to Singapore led to the death of one passenger, while dozens others were injured.
We now have some footage from inside the aircraft, showing the moments after the plane made its emergency landing at Bangkok Airport in Thailand.
The video shows emergency services carrying a passenger from the plane on a stretcher, and the damage caused inside the cabin.

Weather conditions looked very stormy in southern parts of Myanmar with frequent lightning strikes recorded in the area where the aircraft appeared to have lost altitude.
The forecast for that area today indeed suggested there would be isolated to occasional embedded cumulonimbus cloud - more commonly known as thunderstorm clouds - present up to an altitude of 50,000 ft (15,240 metres).
The winds inside a cumulonimbus cloud are the most turbulent with severe up and down drafts.
We don’t know yet whether the pilot of the Singapore Airlines plane was flying within this cloud with some turbulence before hitting a severe downdraft, which would have forced the plane to lose altitude very quickly.
Or, if the pilot tried to avoid the storms, you can also get "Clear Air Turbulence" (CAT), which can be forecast in some areas but unpredictably occur in cloudless skies around the large cumulonimbus cloud.

At Singapore's Changi Airport, officials have set up a waiting area for relatives of passengers in a quiet corner of the terminal.
It's shielded from the public with large barriers, and security guards have been posted outside.
The media - and curious members of the public - have been barred from entering.
Various officials - easily identifiable by their lanyards - have been walking in and out of the area and some are wearing vests that say "care", indicating that a care team is on standby to help the passengers recover from their traumatic experience.

If you're just joining us, here's what we know so far:
In its statement, Singapore Airlines also provided details on the nationalities of those on the flight.
As a reminder, there were a total of 211 passengers and 18 crew on board.
The nationalities of the passengers are:
Singapore Airlines has just released another statement, giving further details on the number of injured passengers.
It says the flight from London to Singapore encountered "sudden extreme turbulence" over the Irrawaddy Basin (Myanmar) at 37,000 feet (11,300m) about 10 hours after departure.
The pilot declared a medical emergency and diverted the aircraft to Bangkok.
As of 19:50 Singapore time (11:50 GMT), 30 people we receiving treatment in hospital in Bangkok.
The remaining passengers and crew were being examined and given treatment, where necessary, at Suvarnabhumi International Airport, the airline said.
"Singapore Airlines offers its deepest condolences to the family of the deceased. We deeply apologise for the traumatic experience that our passengers and crew members suffered on this flight. We are providing all necessary assistance during this difficult time," it adds.
Some news from Singapore's Ministry of Transport, who say they will be deploying investigators to Bangkok.
In a statement, Transport Safety Investigation Bureau (TSIB) officials say they will liaise with counterparts in Thailand to look into the Singapore Airlines flight SQ321.
The TSIB is statutory board under Singapore's Ministry of Transport and is an independent investigation authority.
It is usually responsible for the investigation of air, marine and land transport accidents and incidents in Singapore.

Reporting from Singapore Changi Airport
I'm at the arrivals area of one of Changi Airport's terminals, where airport officials have set aside a spot for the media to gather.
It's a typically busy weekday night with a steady stream of passengers passing through the doors.
In just a few hours a Singapore Airlines plane travelling from Bangkok will land, carrying some passengers from SQ321 who are unhurt and wish to continue with their journey to Singapore.
We understand that the relatives of the passengers, when they arrive, will be escorted to a special waiting area away from the media.
Singapore Airlines has promised to give us more information, and we'll bring you more updates as soon as we receive them.

A British man who was traveling with his family on the flight tells me how the turbulence began.
“It was probably 10 hours in the flight, so there were people walking around. And there was no sign to put the seat belts on," he says.
"There was no turbulence prior to that. It went from no turbulence to this one turbulence. No plane shaking at all and then I was hitting the roof. All of a sudden, I was up like that.
Quote MessageMy son was thrown down on the floor two rows behind me. I heard that there was a guy hitting the roof in the toilet and he was injured quite badly, too."

I’ve just been speaking to a British man at the Samitivej Srinakarin hospital in Bangkok who was uninjured but visibly shaken.
He and his father were searching for his mother whom they had lost contact with since leaving the plane.
She had an injury on the top of her head and had bled during the flight. She was conscious but when they landed she was taken in a wheelchair and transferred to a hospital separately to them.
The man said the turbulence had been mild at first. He had just put his seatbelt on but the rest of his family group had not.
Moments later he said there was a big jolt. The father suffered a cut to his head during the turbulence and had a bandage on his head but said he felt OK.
The man’s sister and brother-in-law are also at the hospital with head and back injuries that they did not think were too serious.
They were growing increasingly anxious about their mother and wife.
But midway through one of their calls to the British Embassy, the hospital staff approached and said they had located her in a room on one of the wards here - the men were then swiftly taken to see her.
I’ve been told that the British Embassy have a team en route to this hospital to assist British passengers.
Were you a passenger on board the flight?
If it is safe to do so, you can also get in touch in the following ways:
In some cases a selection of your comments and questions will be published, displaying your name and location as you provide it unless you state otherwise. Your contact details will never be published.
Some more statements from passengers now - Dzafran Azmir, a 28-year-old student, tells Reuters news agency the aircraft suddenly started "tilting up and there was shaking".
"So I started bracing for what was happening, and very suddenly there was a very dramatic drop so everyone seated and not wearing a seatbelt was launched immediately into the ceiling.
Quote MessageSome people hit their heads on the baggage cabins overhead and dented it, they hit the places where lights and masks are and broke straight through it."
Boeing - the US-based manufacturer of the plane involved - has said it is in contact with Singapore Airlines and is offering support.
Singapore Airlines was using a 16-year-old 777 model for the SQ321 service hit by severe turbulence.
The statement from Boeing continued: "We extend our deepest condolences to the family who lost a loved one, and our thoughts are with the passengers and crew."

Image source, Family handoutAt 09:10 this morning, a message appeared on Allison Barker’s phone. It said: "I don't want to scare you, but I'm on a crazy flight. The plane is making an emergency landing… I love you all."
Her son Josh was on his way to a holiday in Bali. Allison didn’t hear anything else for another two hours.
"It was terrifying," she tells me. "I didn't know what was going on. We didn't know whether he’d survived, it was so nerve wracking. It was the longest two hours of my life. It was awful; it was petrifying."
Eventually she did manage to speak to Josh. He had been on the Singapore Airlines flight and described a scene of absolute terror for those on board.
"One minute he was just sitting down wearing a seatbelt, the next minute, he must have blacked out because he found himself on the floor with other people. There was water everywhere, blood everywhere, people's belongings just strewn all over the plane."
Luckily, Josh had sustained just minor injuries. "He's in a lot of pain, I think he's got some broken teeth, injuries to his mouth, but I don't think there's anything more serious than that."
But Allison’s fear is the lasting damage won’t be physical. "When he found out that somebody had died, you can imagine the realisation that it could have been him, that he was so close to dying."
For someone who was already nervous about flying, she thinks the experience will be hard to get over.
"I think it's going to have a lasting impact on him, coming so close to death. It’s just going to reinforce his fears."
A short while ago we heard from Andrew Davies who was on the Singapore Airlines flight - he has sent us an image from inside Bangkok Airport where passengers are being kept.
"One of the Singapore Airlines crew said it was by far the worst in her 30 years of flying," Andrew says.
He describes seeing some passengers giving first aid and also shouting for a defibrillator.
"So many injured people - head lacerations, bleeding ears," Andrew says. "A lady was screaming in pain with a bad back. I couldn’t help her - just got her water.
"Lots of people injured - including the air stewards who were stoic and did everything they could.
"I wish I could have helped more."
Andrew describes people's belongings being "scattered" and "coffee and water splattered the ceiling".
"Surreal," he says.

I’m at Samitivej Srinakarin hospital in Bangkok. We understand that injured passengers have been brought here.
I’m unable to enter the emergency department as they are keeping the press at bay but I can see people down the corridor who look like passengers sitting with suitcases next to them, including a man in a neck brace.
Pictures from inside Singapore Airlines flight SQ321 are now coming in, and the images begin to paint a picture of just how intense the turbulence was on board the flight.
Emergency oxygen masks are seen hanging from the ceiling, as monitors and parts of the plane's interior appear to be torn off.
