police forces across the country have held a minute's silence in memory of pc andrew harper, who was killed while investigating a burglary in berkshire last week. his mother said she was moved by the "outpouring of love" since her son's death. our home affairs correspondent daniel sandford reports. pc andrew harper's family are still in the early days of coming to terms with his death. but today, just a week after he was killed, his mother, father and other close relatives came to the poignant ceremony organised by his force. we gather here one week from the tragic death of pc andrew harper, our dearly loved and respected colleague, friend and proud police officer, son, brother and husband. we're here to offer our respects and to acknowledge his passing. pc harper, who got married just 28 days before he died, was killed responding to a burglary last thursday night.

so in this moment, let us still our busy hearts and minds as we remember our colleague and friend andrew, in silence now. whistle. silence. whistle. pc harper's mother said the family's lives had been torn apart. "we are devastated and bereft", she wrote. "but as andrew always lived with dignity, honour and calmness,

we intend to grieve in this way." in his hometown of wallingford, shops have put up ribbons to represent the thin blue line role that police play, protecting society from crime. releasing more photographs, the family said andrew harper had been a funny, brave, compassionate brother and a generous, caring, loving son. daniel sandford, bbc news. now on bbc news, click. spencer kelly takes a look at the latest techniques in firefighting at the international fire training centre. this week, another chance to see our firefighting special when we tackle blazes from the air, on the ground and even on rails.

in the summerand in the summer and autumn of 2018, california experienced its deadliest ever wildfires. they claimed the lives of over 80 people and whole towns were destroyed. but as residents tried to escape, the firefighters did what they always do, they ran towards the danger. it isa do, they ran towards the danger. it is a profession that relies on courage, education and, increasingly, the latest science and technology to better understand how fires behave and how to beat back the flames.

and if you want to be a firefighter, this is where you learn the craft. the international fire training centre in darlington, in the north of england. this is where brave firefighters come from around the world to learn the latest techniques in fighting all kinds of blazes. they can simulate a huge variety of fire scenarios here, oil rigs, industrial fires. that is an overturned fuel tanker, and they can simulate any size of aircraft from the smallest to the largest. that is an airbus a380 and this is a boeing 747. and it is notjust about hearing up and grabbing the hose. every fire is different. and each needs to be treated intelligently to make sure you and the people you are trying to save have the best chance of survival. wow! my goodness. they

are using the water as a protective shield. so it keeps the two fires apart, using the water. keeping the left—hand one at bay and then extinguishing the right one before we deal with the left. the centre tries to make each scenario as realistic as possible, notjust the fire that the treatment of the casualties as well. it is fascinating to see the science behind firefighting. for example, in a kerosene fuel fighter, water will not put it out. ‘s cone of water controls the blaze so another firefighter can come in with a powder extinguisher. that is what finally tames the flames. and once

they gone, does that mean the job is done? well, that is where this thermal imaging camera comes in to see what our eyes cannot. so want to look like the fire is out you still have to cover the area in waterjust in case there are hotspots. you can see here the event on the top of this engine is still white hot according to this camera. and there are many other ways to detect and deal with fires. lara has been looking at some of them. for the past two years, half of the uk's fire brigades have been deploying these drones. they focus on the safety of firefighters and they are on board hd and thermal imaging cameras can provide much greater visibility which means a better understanding of a fire and the way that it understanding of a fire and the way thatitis understanding of a fire and the way that it is spreading. using a drone

we can get pretty much an instant overview of the entire fire in under five minutes and start moving our machines and our firefighters around just like chess pieces, really, all controlled by drone footage. it also brings us a massive benefit as we can see fires as they develop. team have also use them for rescues and searching for missing people in quarries or in water. hd camera is able to clearly zoom in on a face up to half a mile away. but of course when it comes to the spread of fires, what has happened recently in california is at the forefront of oui’ california is at the forefront of our mind. university of westminster is researching a system that combines sensors on the ground and those in a drone. the aim, a solution for wildfire. these solar powered prototype sensors are tracking carbon dioxide, carbon

monoxide, oxygen, humidity, temperature, gps and altitude. the aim is to combine them into one miniaturised cost effect if version which could be deployed en masse in areas susceptible to wildfires, providing immediate feedback.“ there is something it will alert all their neighbours also, forming to a network, alert, take measurements, convey to the master node which then conveys it further up to the server which then alerts the drones to come up which then alerts the drones to come up and get a visual. the plane comes with all the information that it has got from the drones, from the ground sensors and it knows what the windspeed is what wind direction is, what the temperature variation is did it it knows where the fire will be when the plane rendezvous is and thenit be when the plane rendezvous is and then it makes a list from the air and then the heavens open as they hit the target whether fire is and you can fight fires day and night,

24a you can fight fires day and night, 24 a day with no visibility. meanwhile, this is the stinger. it can pierce through metal and too much any roof, dramatically blasting foa m much any roof, dramatically blasting foam or water into the heart of a blaze. the quantity and force of that water is pretty incredible. this pumps at 1000 litres a minute with an even more powerfuljet to the side are capable of 4.5 times that. it also has an on—board thermal imaging camera to assist with the precision. blackburn is currently the only uk fire service using this kit. i'm told it costs around £600,000. but maybe as costs drop and this technology evolves, this next generation of firefighting will become the norm. that was lara.

and back at the international fire training centre, i am about to be shut inside a mock boeing 747. see, when it comes to fire, sometimes it is not the one right in front of you thatis is not the one right in front of you that is the most dangerous. it is the one that is waiting to ignite. this is to demonstrate what happens when flammable vapours reach an ignition source up high. it is called a flashover and it looks like this.

i tell you, just a tiny bit of fire in this enclosed environment really shows that smoke is the real killer. my shows that smoke is the real killer. my goodness, you can hardly breathe, it is streaming eyes. they use so much water here every year that it would be silly of me to try and reuse it so that is exactly what they try to do. all the water, the kerosene, foam, powder and sludge from the slate —— site load underground into a drainage system and end up in a small lagoon over here where the kerosene floats to the top and is skimmed off and they can actually really use it. it will burn again. the rest of the lid would end up in the next lagoon where the social —— solid settle out and all you are left with is a watery foamy mix which gets pumped over there. the foam is made of animal protein which he reads actually feed off. so they effectively suck the foam out of the liquid. 0r effectively suck the foam out of the liquid. or you effectively suck the foam out of the liquid. 0ryou are effectively suck the foam out of the liquid. or you are left with at the end of the day is relatively clean water. as well as the practical

firefighting that happens here at the international fire training centre, there is 20 of theory to be learned about the unusual ways that fire can behave. a real danger to firefighters is when the fire in a sealed room starves itself of oxygen so sealed room starves itself of oxygen so it looks like the fire has gone out but the whole place is still really hot. and if a firefighter opens a door to come in, oxygen roles in and starts to mix with the gas and they become flammable again and that's when you get a bank d raft. so... wouldn't it be good if firefighters could use technology to see what they are getting themselves into? that is what paul has been looking at in switzerland. for

firefighters, it is often the things they cannot see that are the most dangerous. the helmet i am wearing has a thermal imaging camera fitted to the side. what is unique is that it incorporates a small google glass style heads up display. it is visible over one eye giving firefighters thermal imaging without obscuring normal vision. firefighters thermal imaging without obscuring normalvision. i'm firefighters thermal imaging without obscuring normal vision. i'm going to use it to enter this very smoky room and see what i can see. it is not too smoky and here at the moment andi not too smoky and here at the moment and i can actually still see but once the smoke really starts to get up, as strange as it may sound, my hearing is going to completely disappear. ina in a modern building, there is a lot of synthetic and materials, buildings are close together. so there is a lot of smoke development

and fire actually may be hidden behind smoke or they may were you don't see it, the thickness of the smoke is a real issue for firefighters. you always have access to the image which starts adding some additional advantages then, which as you would also use the thermal camera where before it was impossible, working with the firehose, you can see as well if you are right, for example justice firefighters protect us, keeping them protected is also critical. and nothing is also more important than the clothing they wear. one of the biggest issues with firefighters right now is that their gear prevents them from evacuating their own body heat so lots of developments actually go in the direction of preventing heat stress for firefighters. making their uniforms fireproof and heat resista nt uniforms fireproof and heat resistant is a no—brainer but doing

so resistant is a no—brainer but doing so well making it flexible, breathable and light is a whole different challenge. at the dupont european technical centre in geneva, they've developed a material which can withstand extremely high temperatures. it's made of a material which bubbles when exposed to high heat, insulating the wearer. it has been proven that if your body temperature and core temperature raises above a certain level, you start doing the wrong decisions, it affects your main function and that's exactly what you do not want to have happen forfirefighter. eventually he would not realise when he is in extreme danger or would realise it too late. you can feel how raised the surface is, these bubbles, for want of a better word, have kind of lifted off the fabric compared to the bit that hasn't been exposed to the fire. naturally, these fabrics have to be vigorously tested and certified and in the

centre's own lab, they conduct a variety of burning tests to ensure the materials are robust. as a comparison, i looked at what happens when the same tests are conduct it on regular cotton. the result was rather terrifying. my goodness. on regular cotton. the result was ratherterrifying. my goodness. i mean, it's completely on fire. yes. it's burned through. they've also developed a smart heat sensing glove that firefighters can use to detect the temperature of a surface or doors to help big tech —— protect against back drafts. now, switzerland may not be the first place when it comes —— that comes to mind when you think of fire. but it's surprisingly advanced when it comes to firefighting tech. for example it's the only country in europe to have a firefighting train.

this cabin is actually rationalised so this cabin is actually rationalised so in the event of a fire, this can be operated as a safe reading environment. this bad boy is one of 16 used across the country and it's an absolute beast. it can be used for a wide variety of tasks, only some of them specifically related to firefighting. it can be used for a rescue ——as a rescue vehicle for people other trains, it can pick up the rail trains or it can simply be used to transport fire crews more quickly and directly by road. but let's be honest. fighting fires is the coolest thing this train can do. it holds 43,000 litres of water and

1000 litres of special firefighting foam. also, a foam canon! it can also create a curtain of protection, also create a curtain of protection, a mist of water that blankets around the train, providing a protective area from smoke and chemicals. so far, at the international fire training coming up centre, i'd be learning how to physically deal with fires but in large disasters, the co—ordinators of the ones who need to see the bigger picture and try and control the entire scenario. it looks like the passengers are already evacuating so can we get a fire at clients to start extinguishing the fire over there? we really need to stop that by getting to the main body of the plane. this simulator allows me to ta ke plane. this simulator allows me to take the role of incident commander.

i got crew commanders sat at each of these workstations. they are in charge of each fire appliance. my job is to make assessments and call commands to them to try and deal with this fire which already looks quite serious, i have to say. it's the only carriage on fire. the only courage? number five. oh, well. that was an explosion. something is telling me this plane would be flying very soon. so as well as an incident commander, you can swap roles, become a nurse or paramedic 01’ roles, become a nurse or paramedic or police officer as well. i can see why this is an intense experience even though it is just a simulation that you really have to have your wits about you to make sense of a very rapidly developing situation. now this is not the only kind of simulation used by first responders. kat hawkins has been looking at our

virtual reality is being used to assess the aftermath of an emergency. i am at leicestershire fire and rescue, the first service in the country to invest in virtual reality. their hope is that money will be saved by replacing some of the expensive traditional training techniques with vr alternatives. i've seen the demo and the fire looks quite intense so i don't think it's going to be what i'm used to when it comes to virtual reality which isjust when it comes to virtual reality which is just having a when it comes to virtual reality which isjust having a nice time. let's see. all the scenes in the trainingi let's see. all the scenes in the training i scanned from the real world. for instance, this arson hotspot in leicester is a good reference for investigators looking for clues. it's the inside of a destroyed smoke alarm. ijust need to say, the environment is like i'm

standing on ash. it feels very real. teleportation. 0h, standing on ash. it feels very real. teleportation. oh, my gosh. there is a body down there. if you enjoy training, you get more out of it. it's already been proven by a study in the united states that he you --if in the united states that he you ——if you train in a virtual reality environment, the retention rate is 7596. environment, the retention rate is 75%. most of the talks i do on road safety, with powerpoint, we tend to make 5% you can see why we're looking at this because the training is going to be enhanced so much. ten seconds forward, you can do it on the control and skip forward see can fa st forward the control and skip forward see can fast forward fire. you remember from the scene a minute ago, that monitor was completely melted. and you can see how it physically at that thing is that is not even burning yet. yes, and idea is how it stops, you don't show the people putting up the fire, you get the ability straightaway to dive back in the scene and now you're in that same

burned scene. seeing the impact of that fire is pretty remarkable. it moves quickly. it's an immersive experience and the ability to hold objects, to photograph them, to mark them. we don't often see the initial development of a fire so for fire behaviour and how far developed in a fire scene, it's useful for mind but from a forensic perspective and training new people in this field, i think it will be invaluable. part of the reason this experience feels so intense is the realism behind it. for leicestershire fire and rescue, this was important, that they move away from game furcation and into real life. they been working with a company called river to make this happen. the scenes are done with photogrammetry, cameras and lasers

photographing real—life 360 degrees scenarios up to thousands of times. we've seen how fire services are using virtual reality but what about other first responders. using virtual reality but what about otherfirst responders. here using virtual reality but what about other first responders. here at the defence science and technology laboratory, they are hard at work on how police might use virtual reality in theirtraining. how police might use virtual reality in their training. number seven, ferguson house. violent disturbance. ican ferguson house. violent disturbance. i can see already. i don't think people would expect to police and virtual reality together. why is it so virtual reality together. why is it so important that the police are interacting with technology in this way? you replicate one-off events so one of the events which could be a dangerous or hazardous environment, you can actually recreate one—off and people would never, ever get the opportunity to rehearse that but in vr, we can so we can given that vehicle and that opportunity to do a one—off scenario and do it safely.

0h, one—off scenario and do it safely. oh, my gosh. 0k. one—off scenario and do it safely. oh, my gosh. ok. i'm going to see if this woman is alive. she's obviously taken some pills. there is a heartbeat here. i can definitely see already how it would be used, in a way that a lot of games are really, to open up your mind to possibilities around crime, why people may have committed criminal activities, those kind of questions are already there. that was more enjoyable in the fire one, i think. that shouldn't be my takeaway but i could go back into that world where is the fire scene, i just wanted to get out. and that's it from the international

fire training centre. i hope you found it as fascinating as we have. we're going to put a load more footage and photos from this place up footage and photos from this place up social media. don't forget, we live on facebook and twitter on bbc click but for now, thanks for watching and we will see you soon. hello there. on friday, the temperature reached 28 celsius in hull but it could be a record—breaking bank holiday weekend. we've got a lot of heat and sunshine to come this weekend but there is the risk still of one or two showers because not only are we drawing in the heat from the near continent around that area of high pressure, we are also increasing the humidity.

and we've still got low pressure sitting towards the north—west of the uk and this weather front is hanging around too. for a while, it'll be quite breezy in the north—west corner of the uk but away from here, it looks like we'll have clearer skies and those temperatures will dip away to 11—14 degrees. now, we've still got more cloud for the north—west of scotland and northern ireland on saturday and maybe a few showers to come for the highlands and islands, as well as fermanagh and tyrone but away from here, lots of sunshine across other parts of scotland and across england and wales and that heat will build very quickly in the light winds and strong sunshine so warming up across the eastern parts of northern ireland, the central belt of scotland, highest temperatures for england and wales widely the high 20s, peaking at 30 or so in the south—east of england. very warm for the ashes day three at headingley. 27 degrees or so in the afternoon in the blue skies and light winds, and it'll be lovely end to the day for many parts of the country. a fine evening to come. the showers in the north—west and across northern ireland, probably tending to fade away overnight. some of the cloud will drift its way into western parts of england and wales, mind you. 00:27:55,427 --> 2147483051:50:42,428 probably not producing any showers 2147483051:50:42,428 --> 4294966103:13:29,430 and temperatures again, 11—14.
