an engine on a united airlines plane burst into flames showering large chunks of debris onto homes and drivers in the us state of colorado. despite the fire, pilots on the boeing 777 which had 241 people on board managed to land safely at denver airport. the military authorities in myanmar are facing mounting international condemnation — after reports that soldiers shot dead two protesters in the city of mandalay. another 20 demonstrators were injured. it's the worst violence yet during more than two weeks of protests against a military coup. protesters in barcelona have clashed with riot police and smashed up shops in a fifth night of protests over the jailing of the catalan rapper, pablo hasel. police fired tear gas at demonstrators during the disturbances. hasel was convcited of glorifying terrorism and insulting the monarchy in his lyrics.

now on bbc news, click. this week, military training in vr. cardboard computers. and, you coming round to the clubhouse? it's time to find out what everyone�*s talking about. hey, welcome to click, hope you're doing 0k. lara, how are you this week? good, thanks, just about managing to stay entertained. i keep going through phases of what i'm actually doing this week it's been all about live radio. do you know, me too! i'm listening to more and more

live radio these days and ijust feel i need to hear a live human voice coming through the speaker rather than a song playlist. i feel like i need the company. do you listen to just uk stations or have you gone further afield? funnily enough i used to use tune in to listen to antarctic radio when it was a thing. it was cool and it was folky. really? there is also radio garden which allows you to listen to over 30,000 local radio stations from across the globe. fancya spin? yes, please! it's almost like peeking through the window of someone else�*s party! a collaboration between two interactive design companies and the netherlands�*s institute for sound and vision, the platform, now in its fifth year, has grown hugely and allows any station to appear afterjust submitting an application online.

basically we are using internet radio and it's quite an ancient technology by now. all of these radio stations broadcast online and through the web we are basically able to link to these streams that are already occurring. we just embedded on the platform and you just play them. radio garden encourages you to explore four hours. by transporting you to different places, it may offer some much—needed comfort. last year we went very viral in italy during the last time when many people were sick and dying and we were seeing selfies of doctors and hospitals taking care of people and it was like very emotional and impressive to see, like, how radio garden touches people. that's a lovely thing, isn't it? and in a way it points towards one of the big tech trends at the moment which is seen good old audio having a bit of a resurgence.

podcasts are changing hands for silly money these days and there is one particular audio—based app which is creating a bit of a buzz in silicon valley. clubhouse is a mash up of social network, events platform and live podcast. and everyone�*s getting a bit giddy about it. but are they right? lg rich has been finding out. how we communicate online is about to change. we're used to social media containing text, images and videos, but now good old—fashioned voice chat is making a comeback. everyone can be a host on clubhouse. it's an audio only social network where celebrities, entrepreneurs and pretty much anyone with an account can hold their own show. you can even drop into a discussion. what was the learning experience like for you to put that whole production together? into the app and you will see thousands of audio chat rooms hosting them.

you can also follow people or subjects. it's like stepping in and out of lots of different conference calls or live podcasts. clubhouse is still in invite—only beta but even though it is only available on three devices it has had 4 million downloads in the last month and attracted $100 million worth of investment. find an event, topic or interview that picks your interest and go in. were free to stay silent and listen or even join in conversation yourself if you feel brave enough to raise a hand. after the chat ends, the room disappears and there's no option to listen again. let's keep going and have fun because it is a bleep up at the end of the day. dropping in on unmoderated conversations means there is a chance of hearing something controversial or offensive, so it'll be interesting to see how harassment and misinformation is handled on an audio platform. certainly, there are

technologies around audio monitoring and listening but deploying them, right, also creates a certain dynamic with the community in terms of, you know, these conversations are being recorded and tracked and all of that stuff. but clubhouse aren't alone in the move to audio—based social networking and the tech giants are working on their own versions. facebook is set to be building a competing product but way ahead is twitter with this offering spaces. and it's also invite only beta testing. up to 11 people canjoin a space for now and listeners request to speak by raising a hand icon. 0ne huge advantage twitter has over clubhouse is that users already have established followings so there is no need to start from scratch. it was close to 200 million daily users, there will be no shortage of topics

to tune into. we crave conversation and though text takes you a good bit of the way, what it lacks the empathy and nuance that comes from the voice. it comes from hearing. sometimes there is nothing more meaningful than to hear somebody�*s voice. i hope that because of that unique interaction between the text based, live nature of twitter, and the connection back to spaces that it's going to be big. how does anyone moderate audio? to do so with audio requires us to think about things like muting controls, being able to invite people to the conversation to speak and knowing when to have somebody say, all right, time's up,

pass the mic. knowing whether or not you want to close a space so people can feel safe, depending on the nature of the topic, or make it more open to others. feel free to have a conversation about anything, even something controversial. but do so in a way that feels inclusive, respectful and empathetic. the buzz around clubhouse and other tech companies getting in on the conversation shows at least there's an appetite for this format, certainly one talking point is that audio could signify the next game changer for social media. hello and welcome to the week in tech, it was the week that mass layoffs were reported at flying car company to refer geo just weeks after its transition granting her hybrid was given a license or take—off by the federal aviation authority —— terrafugia. microsoft updated its accessibility guidelines, launching a new testing platform for developers of pc and xbox games to make gaming more accessible. and after a seven monthjourney, nasa's perseverance rover landed safely on mars. sending its first

images back to earth. it will spend the next two years looking for past life on the planet. it was also the week that facebook banned the sharing of all news, local and international, in australia across its platform, rejecting a pay for news proposal. uses outside of australia are also unable to read or access any australian news publications on the platform. the proposed law, which passed through the country's parliament, would force companies like google and facebook to pay for news content. 300 human linejudges on 18 tennis courts could be replaced at this summer's wimbledon by the hawk—eye live system. the all england club is looking at the use of the technology to replace line judges at the australian open. the first time they've been replaced by this tech at a major tournament. and finally this week on al robot has announced herfirst art exhibition in london. ada will be exhibiting at the design museum in may.

and after ada lovelace, her exhibit is expected to feature self portraits and a font she designed. vr has had its ups and downs, hasn't it? we're supposed to be the next big thing, it's never quite got there but it has found its feet in areas like gaming, movies, conferences. and it has really taken off, i think, in training, and i know the other presenters have looked at that before but i was interested to find out what happens when you really push vr to its limits. can it match up to the real world when it's a matter of life or death? i'm heading to raf honington, where the raf regiment is about to conduct some tests of a new vr system developed by a small british tech company. tom constable�*s the developer who's created the vr tech being used today. in 2018, tom started a company

building training tools for the military, based on the 0cculus rift is headset. i connected the dots between my military background, my degree in computer games design and the new technology that was coming up and it was clear literary application for virtual reality training. in 2020 the uk government's security accelerator announced that tom's company would be given a series of trials using his vr technology known as saftac. it's these trials we've come to see, and the results will determine whether his vr tech will be adopted by the british military. big day for you, how are you feeling? looking forward to it. are you ready to get involved in saftac? i am the wrong person to train you on military tactics are happily enough i have simon mitchell who will help you take you through some skills and drills. if you look down, grab your hands, you should reach forward and you feel the controllers as you grab them. this is a surreal thing to do.

so normally when i look at my feet i see high heels and a handbag and now i have an assault rifle. you have all of the kit you need to take on an enemy position which is great. so now for a crash course in military training. you can grab the grip on the rifle. i've got it. brilliant. oh, my word! oh, no, i dropped it. oh, god, ijust fired it. wow, it's a terrain that i'm not at all familiar with but i think is a training exercise actually it is pretty good so far. training over, it was time for the section attack. enemy within. for most of us the closest we get to being shot at his in video games but for these young gunners, being shot out could be a reality. for them, this vr experience is no game. but the software used to create this experience has been influenced by gaming. tom's vr training tool is based on software called the unreal engine, which was created

by the makers of the popular game fortnite. you have now been transported to a whole new domain. platform announced developers to create and run 3d virtual worlds using ready—made parts, for example, like the in—game physics, to make bullets fly the right way. it has flat furniture for gaming software. the benefit of the unreal engine for game designers is that it can be constantly updated, improved and added to by everyone, something tom has made the most of. the airfield for example we have been training on today was bought from the marketplace for, i don't know, say $50. i then took that, i optimised it and changed it to the specific use of these guys wanted but within a day i had an airfield ready to go within saftac, which i think again is probably new to defence, they are not used to that kind of rapid process. this type of rapid development means that environments could be specifically created for each mission.

the time had come to use my new—found military tactics in the vr section attack. i am going around this corner. and now i'm going towards, between these two hangers. charlie, in position. ok, so now... i am so nervous. this gun is actually shaking in my hand. start moving now. please, don't shoot! hands in the air! on your knees! stop, stop, stop, troops. well done! you've played to the scenario. i found the control is quite difficult. it's taken me a little while to get the hang of, you know, holding on to the weapon. there's a much else going on. yeah! that's weird, isn't it? so i have yet to compare it to the real thing but are you going to look after me tomorrow as well? so now to the moment of truth. would any of what i'd experienced in virtual reality actually prepare me for the real thing? apparently i'm going to need a bit more kit

this time. thanks, 0z. enemy down! for the raf regiment, when the bullets start flying for realm any mistakes could lead to lives being lost and so there can never be enough training opportunities. being in the thick of it really hammers home how virtual reality can never totally prepare you, but that doesn't mean it can't be a useful training tool that complements these exercises. vr could never simulate the shockingly cold temperature in this hangar, but on the other hand, in vr, the raf regiment gunners can learn what to do when enemy shells are exploding during an attack, something that can't be easily recreated on the training field. well, cold or not, my heart is pumping. just need a second.

you can't really explain the adrenaline, i think, what you don't get in the vr isjust how, you know, how loud that gunfire is. even though i felt prepared coming here, i was thinking, i'm doing it, i did it yesterday, it looks kind offamiliarto me, i'm going to be ok, and i am 0k, but you just can't beat the intensity, i think, of that physical world experience. it's been completely on another level. but of course, i'm not the expert here. for tom, what the troops think is crucial. you really need that buy—in, don't you? absolutely, yeah, fundamental. this is not going to get off the ground without buy—in from the personnel. and, yeah, if i didn't get invited back after the first one, then i'd know my answer. so, time to find out what the professionals thought. i'm not particularly au fait with gaming or virtual reality but if the truth be told, with, in, probably a couple of minutes of wearing the equipment, the benefits of undertaking virtual reality training were immediately

apparent to me. but ultimately, there's one person who has to see the value in vr for the armed forces, and for that, you have to go right to the top. i think in all of the environments in which we use synthetic training, there's real operational advantage in doing so. i mean, it feels like the genie is already out of the bottle. it's obviously the way forward and we're excited about integrating it even more into the way we do our business. when i left tom, i said, you know, we don't know whether his dream is going to come true and this is going to get the investment. can i phone him up and give him some good news after this? well, you can tell him that all appears to be going very well indeed. i don't think we have made a final decision yet. but it's a product that has been very, very well received

by those who have used it so far. the vr concept, i think, is accepted as the way that we're going, but exactly which product we buy is a decision for others to make. but i'm not sure the company could have done any more. so it's good news for tom. and it looks like virtual reality is indeed part of the future of military training. while vr can't yet come close to the real experience, it seems widely accepted it's a very handy supplement. ultimately, on the battlefield, fine margins mean life or death, so the extra preparation vr training provides could be critical. zoe kleinman there. now, spencer, something's been bugging me for all this time. what's going on with your click sign? ah, yes, i was wondering when you would notice. are you ready? one, two, three! 0h? it's not the real one! look at this! laughter. it's a cardboard version! it's been sent to me. i've also been sent something else, which is absolutely beautiful. this is a cardboard version of a very important part

of my life — the bbc micro. isn't it lovely? wow. that's really cool. so, both of these have been made by a former computing teacher, now a stem champion who has been teaching technology in a very unusual way, namely, using cardboard. hello, i'm alan 0'donohue! i'm here in my home at the cardboard museum of computing! for me, it started with this cardboard mac classic. one of the first computers that had a mouse with a graphic user interface. yeah, i certainly do remember the first apple macintosh computer, debuted by stevejobs back in 1984. so, i had no idea when i built this cardboard version that it might lead to some more cardboard computers, and then maybe even a whole museum? and this is just such a beautiful bbc micro.

so i started making these during the lockdown, and i think it's a really nice activity to get you away from your screen, to be thinking about computers and technology, but in a different way. and if you fancy making your own models, then these paper cut—outs are available online. we have a microzbit, codebug, a memory device, an arduino. it's a very small, pocket—sized museum that people can download. and the inspiration seems to be catching. since i started sharing some of these projects online, other people have been inspired to build some themselves, just using cake or lego... inspiring technology doesn't have to be all coding and computer chips. we've got to be careful that we're not forcing too much technology on ourselves and our children.

just spend some time unplugged, away from the computer, and see what you can create. though, i'm not sure i've got space at home for the largest piece in alan's home museum — a section of what's widely regarded as the very first programmable electronic digital computer. that's a lot of cardboard! but i do know where it lives in real life, over in the uk's bletchley park — alex humphreys has been to check it out. you may have seen bletchley park in the movies — yep, that one with benedict cumberbatch playing alan turing. during the second world war, this was the home of the codebreakers. beeping and whirring the uk's smartest minds, who, through sheer determination and extreme intellect, managed to break

the secret code the germans used to send tactical messages from berlin to forces on the ground. this is the very latest, the bbc microcomputer... but i'm here to celebrate a different hero, perhaps one of education — the bbc micro. it's turning a0 this year! these computers were launched back in the 805, and the aim was to get kids programming. and it worked! it was so successful. and as result, many in the uk would have started on one of these. it was made by acorn computers, the so—called apple of the united kingdom. around 1.5 million units were sold. and thanks to a government subsidy, it went into more than 80% of primary schools in the country. tom is the man in charge of the bbc micro exhibit he told me a bit more about why it was so successful. it had a very good programming language with it, bbc basic, and that meant it was really good in education and was used well by industry as well. it was one of the fastest industries about, for its time

when it launched, so streaks ahead of the competition for a very low price point, really. ok, so i'm getting to play on a real micro. i am playing chuckie egg. it's taken me about a quarter of an hour to work out the controls. this is so cool, i love it. but i'm not the only one playing. the museum invited gamers across the country to take part in the microlympics, giving players a chance to play classic bbc micro games on like repton, citadel and elite on emulators online. a far cry from the likes of fortnite and roblox, but it gives kids a chance to experience what their parents might have played back in the 805. they're very different! like, the overall concept, and also the controls, you've got to be more focused.

i normally play, like, games like mario kart, like, the graphics are quite different. it was a lot more simplistic and also like, the sounds. it was still interesting and just as fun. i find the controls quite difficult. - very. i thought they were quite random, like, you have 0, s and t, which are far apart on the keyboard. thousands of kids and adults alike have since found inspiration for coding in its descendants, the bbc micro:bit, and its version two, which launched in october. and so the legacy of this great british computer lives on. 0h! that brings it all back, it really does! chuckie egg, repton, elite, brilliant! honestly, the bbc micro is the reason that i do what i do today, and why i fell in love with computers. so, happy birthday, bbc micro, mwah! from all of us here at click — that was probably a bit too much, but there you go. and that's it from us for this week. as ever, you can keep up with the team on social media —

find us on youtube, instagram, facebook and twitter, at bbc click. thanks for watching and we'll see you soon. bye— bye. hello there. the very mild south—westerly winds which we've had during the start of this weekend have also brought a lot of rainfall across some western parts of england, wales, northern ireland and western scotland. we have seen some local flooding in places, river levels running very high. and as a consequence from all the recent rain, the number of flood warnings has increased. but the good news is for part two of the weekend, it looks a bit drier across the board. we should see quite a bit of sunshine around. it's going to stay mild, but there will still be some rain around but not as much

as what we had on saturday. now, the rain will be courtesy of this weather front, which will start out across more southern and eastern parts of england. low pressure to the north—west of the uk will bring fairly breezy conditions to northern ireland and scotland, where we'll start off for sunday with a few showers here. cloudier skies with outbreaks of mainly light and patchy rain across the south east will slowly work their way westwards. so, by the time we push on into the afternoon, parts of the north and west midlands, into wales and the south west could see some heavier rain, but not as heavy as what we had on saturday. and it'll be brighter into the afternoon across the south east, where it'll be very mild, but even mild further north and west, too. now, through sunday night, that weather front persists across much of england and wales. that's going to bring cloud, outbreaks of rain, some of it could pep up to be heavy again across wales and the south west, so we'll have to just watch that. across the south east, it'll be drier, and drier across the north west. for england and wales to start monday morning.

we still have that weather front lingering across parts of england and wales, but through the day, it'll start to push northwards and eastwards and begin to fizzle out. so conditions will improve here. one or two showers across the north west of scotland, but otherwise a good deal of bright and sunny weather around. a little bit cooler, you'll notice, across the north and the west, but very mild again across the midlands and the south and east. now, as we head on into tuesday, we see a new area of low pressure that's going to bring renewed weatherfronts with more rain, stronger winds here as well. but it'll also be drawing up some extremely mild air off the near continent around the middle part of the week, certainly for england and wales. and that really will be noticeable around the middle part of the week. i showed you 17—18 degrees possible in the south east. some rain in the north and the west, and then there's signs of it by the end of the week, high pressure building in, which will turn things drier and brighter for all of us.

this is bbc news with the latest headlines for viewers in the uk and around the world. an engine on a passenger plane bursts into flames above the us state of colorado — scattering debris on to homes below. passengers describe the heartstopping moment. you could just feel it, like, boom, and you could hear it and you just...we started shaking. gunshots mark the escalation of violence in myanmar. the military faces mounting international condemnation after reports that two protesters are shot dead. unrest on the streets of barcelona as thousands of people protest for a fifth night against the jailing of a rapper for controversial tweets. and it's finally bloomed — a rare cactus from the amazon rainforest has flowered for the first time in the uk as thousands watched online.
