Could Climate Change mean well see more of these events . Well be joined be a scientist who has spent a decade researching just that, and also, the head of the airline pilots� union balpa. This is Paula Vennells, who is at the heart of the post office scandal. She finally gives evidence tomorrow. Well be asking lord lord Arbuthnot Who played a pivotal role in the postmasters� campaign what he wants to hear from the woman who was in charge. Also tonight. Will tomorrows Inflation Figures give the government a boost, or are Cost Of Living concerns so endemic, will it even register . 0ur Economic Experts will give you the answer. And tomorrow, the mp Craig Mackinlay returns to westminster, after revealing the extent of what he describes as Extreme Surgery after sepsis. There was discussions happening about these arms, and legs. Because by then, they had turned black. They were like a plastic. You could almost knock them. And it was like. It was like a. Like your mobile phone plastic. Tonight, 0livia giles who also had her hands and feet removed because of sepsis tells us how shes recovered. And dr ron daniels. The Chief Executive of the sepsis trust. He tells us what signs to look out for. Good evening. Singapore Airlines Flight 50321 headed from london to singapore did not go according to plan, when the plane was hit by severe turbulence over myanmar and dropped dramatically and unexpectedly. 0ne passenger died of a heart attack. Geoffrey kitchen was 73. Seven more passengers are critically injured, 23 more have suffered less severe injuries. Severe turbulence can be forecast, but another form, Clear Air Turbulence, is harder to detect, and so can be unpredictable. The bbc� s South East Asia correspondent, jonathan head, spent today at Bangkok Airport. Jonathan, thank you very much for joining us tonight. Tell me, what have passengers been saying to you about what happened to them . Well. About what happened to them . Well, the have about what happened to them . Well, they have described about what happened to them . M they have described what was a smooth and uneventful flight. They have described what was a smooth and uneventfulflight. It they have described what was a smooth and uneventful flight. It was towards the last stage of this flight, usually about 12 hours, i have done it many times myself on Singapore Airlines from london to singapore. Those last two hours before they descend to singapore as they go over myanmar and thailand which is about the time they serve breakfast after a nights flight. A lot of people had got up to use the bathroom after waking up and it was then that some say the Seat Belt Light went on and there was a little bit of turbulence and then suddenly, this incredible drop. And absolute chaos. People covered in other peoples breakfast and coffee. A lot of the oxygen masks came down. All sorts of other debris was thrown around. People described seeing items just floating up around. People described seeing itemsjust floating up in around. People described seeing items just floating up in the air. And of course, people who were not secured by seat belts smashed up into the air as well. It didnt last very long despite that dramatic 6,000 foot drop, just a few seconds. And then after that, they say a very strange calm as people sort ofjust dealt with the shock of what had happened. It came completely out of the blue. 50 happened.

So of the people you havel spoken to today, you have spoken to some of the injured and do you get a sense of the impact they were faced with . We know there were dense in overhead cabins.

Those who are not secured me yes. Most of the injuries are relatively minor, but there are people the fractures, severe bruising, a lot of cuts. Some of the cabin crew trying to help passengers had their own faces covered in blood because of cuts because they tend to be moving around the cabin at that time. We dont know the exact injuries of those having to remain in hospital, but there are a number of people who will remain there for some days while their injuries are treated here in thailand. find while their injuries are treated here in thailand. While their injuries are treated here in thailand. And there was a sad death of here in thailand. And there was a sad death of course, here in thailand. And there was a sad death of course, but here in thailand. And there was a sad death of course, but the sad death of course, but the passengers who are not severely injured, are they returning home going on, what has been happening . Well, they have sent a plane here to Bangkok Airport to pick up those on injured passengers who remain on the flight side of the airport in the day those passengers who are not injured. They arrived in singapore injured. They arrived in singapore in the last few minutes. Speaking to passengers today who are on much longer flights, passengers today who are on much longerflights, one Family Passengers today who are on much longer flights, one family going to australia for a wedding, they say they dont want to go on and they cannot face a succession of fights and just want to get back home again. I suspect the some of those who have been injured or who are deeply shaken by what happened, they might want to cut their flying short. It has been a really shocking end to a flight and i think it is an awful lot for people to process. These flights feel very safe. Singapore airlines is a very reputable airline and normally, the flights are enjoyable and nothing usually goes wrong. Something like this seems to be completely unpredictable. This seems to be completely unpredictable. This seems to be completely unredictable. ,. ,. ,. , ~ ,. , unpredictable. Jonathan, thank you very much unpredictable.

Joining me now in the studio, Amy Leversidge general secretary at the British Airline pilots association, who represent 85 of britains airline pilots, and paul williams, professor of Atmospheric Science at reading university. A scientist who has spent a long time looking at the questions about turbulence. First, amy. How much of an issue is this kind of turbulence for a pilot . For a pilot . Well, first, we would like to express for a pilot . Well, first, we would like to express our for a pilot . Well, first, we would like to express our sincere like to express our sincere condolences for everyone who has been affected by the terrible tragedy today. And turbulence is quite common, probably most of us will have experienced turbulence. But that is very slight turbulence. This kind of severe turbulence as seen on this incident is very, very rare. Pilots are highly trained. Extensively trained. They do lots of simulated training to try and deal with these types of situations and they have got lots of on board Monitoring Equipment to try and prevent this and avoid it. But toda , prevent this and avoid it. But today. That prevent this and avoid it. But today, that didnt happen. Last night, overnight, ishould today, that didnt happen. Last night, overnight, i should say. Today, that didnt happen. Last night, overnight, ishould say. And i wonder if from your Point Of View as a scientist, something is going on here, what kind of turbulence is this . I on here, what kind of turbulence is this . ,. , , on here, what kind of turbulence is this . , ,. ,. , this . I would emphasise again the rari of this . I would emphasise again the rarity of this.

The last one i turbulence are really rare. The last one i know turbulence are really rare. The last one i know of before today happen in 2009 one i know of before today happen in 2009 and one i know of before today happen in 2009 and before that in 1987, so it is not 2009 and before that in 1987, so it is not even 2009 and before that in 1987, so it is not even a one senior event. It is not even a one senior event. It is more is not even a one senior event. It is more like is not even a one senior event. It is more like once in a decade. That is more like once in a decade. That is because is more like once in a decade. That is because there is not much severe turbulence is because there is not much severe turbulence in the atmosphere. Turbulence Strong Enough to lift you p turbulence Strong Enough to lift you up out turbulence Strong Enough to lift you up out of turbulence Strong Enough to lift you up out of your seat if you dont have up out of your seat if you dont have a up out of your seat if you dont have a seat up out of your seat if you dont have a seat belt on is astonishingly rare, have a seat belt on is astonishingly rare. Iess have a seat belt on is astonishingly rare, less than one tenth of 1 of the atmosphere contains that much turbulence. But take into account all of turbulence. But take into account all of the turbulence. But take into account all of the planes flying in the sky is it any all of the planes flying in the sky is it any given time and one accidentally will find it at some point accidentally will find it at some oint. ,.

I have been studying turbulence for 20 years and how to forecast turbulence for 20 years and how to forecast It Turbulence for 20 years and how to forecast it and the response to climate forecast it and the response to Climate Change has been a particular focus Climate Change has been a particular focus for Climate Change has been a particular focus for the past decade. And in that time, focus for the past decade. And in that time, we have built up a lot of evidence that time, we have built up a lot of evidence that for example tim macrow since satellites began observing the et since satellites began observing the jet stream where there is a lot of turbulence jet stream where there is a lot of turbulence in 1979, the amount of wind turbulence in1979, the amount of Wind Shear Turbulence in 1979, the amount of wind shear in the jet stream where there wind shear in the jet stream where there is wind shear in the jet stream where there is a wind shear in the jet stream where there is a lot of turbulence in 1979, there is a lot of turbulence in 1979, the there is a lot of turbulence in 1979, the amount of wind shear in the jet 1979, the amount of wind shear in the jet stream has increased because of climate the jet stream has increased because of Climate Change turbulence is increased of Climate Change turbulence is increased by 55 . That is a lot. And increased by 55 . That is a lot. And in future, increased by 55 . That is a lot. And in future, we increased by 55 . That is a lot. And in future, we might see a doubling or trebling in future, we might see a doubling or trebling in some parts of the world or trebling in some parts of the world in or trebling in some parts of the world in the amount of severe turbulence by 2060 because of climate turbulence by 2060 because of Climate Change. Climate change. That is so interesting Climate Change. That is so interesting because Climate Change. That is so interesting because you i Climate Change. That is so l interesting because you talk Climate Change. That is so interesting because you talk about pilots, but i wonder if that level and that increase will actually impact the design of planes . Well, lanes are impact the design of planes . Well, planes are highly impact the design of planes . In planes are highly designed to fly through these kind of weather conditions. Planes are designed to deal with this. And pilots of course continually train and continually learnt. �. ,. ~ continually train and continually learnt. ,. , learnt. But do they talk, is there chatter among learnt.

Pilots have a very, very strong j pilots have a very, very Strong Community. We have a Strong Community. We have a Strong Community throughout balpa and indeed, throughout the International Pilots unions well Work Together and talk and share experience. Pilots do this on a day to day basis, they work a team. But pilots do this on a daytoday basis, they work a team. But when ou hear basis, they work a team. But when you hear what basis, they work a team. But when you hear what paul basis, they work a team. But when you hear what paul is basis, they work a team. But when you hear what paul is saying basis, they work a team. But when you hear what paul is saying here i you hear what paul is saying here about Climate Change impacting how much turbulence there is, that is going to make a measurable difference. They work as a team. Not only to training, but other aspects of flying. For example, now on a flight can make you a much less inclined after today actually to release your seat belt, for example. This is what the pilot always says when you get on the plane. Make sure even when the Seat Belt Light is turned off, keep your seat belt buckled and they always say that and try to limit how much time you spend Walking Around the cabin because of incidents like this. As much as they try, they have their monitoring and they are talking all the time, they are broadcasting to air Traffic Control and other planes in the area and they are constantly on the radios and constantly communicating, but they do say that things happen and they happen quite quickly and the best way to do that is to keep your seat belt on. But the best way to do that is to keep your seat belt on. Your seat belt on. But i think now because of your seat belt on. But i think now because of this, your seat belt on. But i think now because of this, there your seat belt on. But i think now because of this, there is your seat belt on. But i think now because of this, there is going i your seat belt on. But i think now because of this, there is going to | because of this, there is going to because of this, there is going to be more conversation now about what happens on board. If it is unpredictable and if it becomes increasingly unpredictable and increasingly unpredictable and increasingly common as well as unpredictable, those two things are going to change what people feel about flying. Going to change what people feel about flying going to change what people feel about flying. Potentially.
