i expect that will increase over the next few hours as airlines struggle to try to get their heads around the logistical nightmare. in these situations, - you expect or you hope that the airline would kind of come out and offer information, - but obviously, in this particular case, they couldn't, _ because they didn't know. a bank holiday meltdown. air traffic control in the uk experiences a serious technical fault which grounded flights all across europe. it could take days for the backlog to be cleared. we will bring you reaction. also tonight, we have a date. donald trump will go on trial in march over his alleged attempts to subvert the 2020 election. and on the 60th anniversary of the civil rights march on washington, we will speak to the family of doctor martin luther king jr.

good evening. the last bank holiday of the summer is always one of the busiest travel days of the year. and not the moment for a technical issue at air traffic control. nats, the body that runs uk airspace, says it has now "identified and remedied" a fault that affected the flight planning system, but for a large part of the day, they were operating manually on a greatly reduced schedule. which means there is still an enormous backlog of flights grounded across europe, with long, long delays. more than 500 flights in and out of the uk were cancelled. it could be 2a hours before some passengers will finally get it could be 2a or 48 hours before some passengers will finally get to their destinations. let's bring in aviation expert doug maclean, who worked in air traffic control for almost a0 years. good to see you. sympathies for all those people stranded outside the uk to mate, or at uk airports. what

went wrong? there are always technical problems from time to time, but this was a big one? yes. time, but this was a big one? yes, it was a big — time, but this was a big one? yes, it was a big one. _ time, but this was a big one? yes, it was a big one. i _ time, but this was a big one? yes, it was a big one. i do _ time, but this was a big one? yes, it was a big one. i do feel- time, but this was a big one? yes it was a big one. i do feel really sorry for the people who are stuck on bank holiday monday, and also business travel as well. this has now become quite a rare event, dare i say probably ten or 15 years ago it was much more common, and the flight data processing system is really vital to running the volumes of air traffic that go through uk and european airspace. when an aeroplane is coming from, say, milan to london, all of the air traffic control centres will receive the flight plan from the aeroplane, and as it gets airborne, it will be updated on the way, so when it comes

to the uk it is where we expected, and we expected and that the height that we expect it. the automated system that feeds that into the computers that display the pictures onto the radar controls greens failed, so it is no longerfeeding more and more information. —— radar control screens. eventually it will run out, and they have to revert to a manual system where they are putting the information in manually... putting the information in manually. . ._ putting the information in manuall , . manually... so, as i understand it, it automatically _ manually... so, as i understand it, it automatically populates, - manually... so, as i understand it, it automatically populates, but - manually... so, as i understand it, it automatically populates, but if. it automatically populates, but if it automatically populates, but if it breaks down, quite naturally, you have to put the details in by hand? pretty much, basically. bear in mind, this has been done well, well in advance. it is not something that

happens immediately as the aeroplanes are arriving into the sectors. that information is fed and well before so the controllers can plan the sectors. we have very good monitoring of the sectors so that it if aeroplanes are arriving from all sorts of different areas, we know the volume of traffic that is coming into the sectors, which is why we are very assured that we can run the sectors safely, because we know the volume that is coming in. when you start to lose the surety of the state in advance, we need to start slowing things down to ensure if you are having to manually transfer data between air traffic control centres or between controllers and airports, thenit or between controllers and airports, then it can't be as slick as it normally would be.- then it can't be as slick as it normally would be. then it can't be as slick as it normall would be. . , normally would be. so, what they did was slow the — normally would be. so, what they did was slow the flow _ normally would be. so, what they did was slow the flow of _ normally would be. so, what they did was slow the flow of traffic _ normally would be. so, what they did was slow the flow of traffic off - normally would be. so, what they did was slow the flow of traffic off the - was slow the flow of traffic off the runways. at a place typically like

heathrow, what difference would that make to the runway and how many flights were leaving... make to the runway and how many flights were leaving. . ._ flights were leaving... well, the complexity _ flights were leaving... well, the complexity is — flights were leaving... well, the complexity is actually _ flights were leaving... well, the complexity is actually in - flights were leaving... well, the complexity is actually in the - flights were leaving... well, the complexity is actually in the airl complexity is actually in the air space once the aeroplanes are airborne, so if you are feeding off gatwick, stansted, heathrow and luton all at the same time, they are traffic controllers who are looking after the airspace immediately after the aeroplanes depart rely very much on having up—to—date data fed into them, which is why we need to make sure everything is ready for them. so, they will probably have reduced the flow as low as 25% or 30% of the normal capacity. the flow as low as 2596 or 3096 of the normal capacity-— normal capacity. obviously that creates a huge _ normal capacity. obviously that creates a huge backlog, - normal capacity. obviously that creates a huge backlog, 500 i normal capacity. obviously that - creates a huge backlog, 500 flights cancelled today. it is not fair air traffic control to say how quickly that backward can be managed, that is for the airlines, correct? it is

expert in air traffic control. a trial date has been set for the criminal case in which donald trump is accused of trying to overturn the 2020 election. the trial will start on the 4th of march — the day before super tuesday, which is the day when the greatest number of us states hold their primary elections. it's just three weeks before he goes on trial in new york on the 25th of march. lawyers for the former president were in court today, to ask for the case to be delayed until well beyond the election, until 2026. but in response districtjudge tanya chutkan said this: in the last few minutes, donald trump and his lawyers have said they will appeal the setting of that trial date, so another court case will be put into the schedule,.

meanwhile, in atlanta, another court was hearing evidence from mr trump's former chief of staff mark meadows. he is asking that the racketeering case brought by district attorney fani willis be moved from state to federal court. in the course of those proceedings we learnt that mr trump and his 18 co—defendents will be arraigned in fulton county on the 6th of september. live now to adam klasfeld — senior legal correspondent for the messenger. asi as i start to set out those dates, you can see quite quicklyjust how the calendar fills, and you can see quite quicklyjust how the calendarfills, and how you can see quite quicklyjust how the calendar fills, and how it complicates donald trump's schedule. absolutely core, and one of the things you just mentioned that the march fourth trial date setting, as you mention, is the day before super tuesday, and also quite close to the hush money case. delivering a ruling in court today, judge tanya chutkan had noted that she had got in touch with thejudge presiding over that case to note the possible conflict. now, remember, the prosecutor in

that hush money case, alvin bragg, had said in an interview that he was willing to potentially make way for the schedule. i wouldn't be surprised if that changes and is delayed, but it is a crowded calendar. in may, we will have the classified documents case come to a head in the district of florida, and there will be the setting of a calendar in georgia. plenty more dates on calendars to be filled up by the former president as he tries to be re—elected. by the former president as he tries to be re-elected._ to be re-elected. judge chutkan in washington. _ to be re-elected. judge chutkan in washington, she _ to be re-elected. judge chutkan in washington, she doesn't - to be re-elected. judge chutkan in washington, she doesn't appear . to be re-elected. judge chutkan in| washington, she doesn't appear to have any interest in granting special measures to residential candidate. do you think an appeals court would be more sympathetic? hat court would be more sympathetic? not onl has court would be more sympathetic? iirrt only hasjudge chutkan not been only has judge chutkan not been sympathetic towards that, the judge in the classified documents case in florida, a trump appointee, said it

wouldn't be helpfulfor florida, a trump appointee, said it wouldn't be helpful for trump's attorney to emphasise the political considerations. these aren't the typical considerations that are brought forward for a court. the considerations are, you have enough time during the evidence, is it in accordance with the speed trial rights, not how does it align with one's can pain calendar. we rights, not how does it align with one's can pain calendar.- rights, not how does it align with one's can pain calendar. we had the mini trial of — one's can pain calendar. we had the mini trial of mark— one's can pain calendar. we had the mini trial of mark meadows, - one's can pain calendar. we had the mini trial of mark meadows, the - mini trial of mark meadows, the former white house chief of staff, appealing for the case to be moved from state to federal court. why does he want that, what is the idea there? , . ., there? there is the idea of potentially _ there? there is the idea of potentially getting - there? there is the idea of. potentially getting friendlier there? there is the idea of - potentially getting friendlierjury potentially getting friendlier jury pool in federal court ban in fulton county, georgia. it is broader territory in its jurisdiction. county, georgia. it is broader territory in itsjurisdiction. that could be one of place. another one

that meadows's team has put forward is that he could argue that he is immune from prosecution. the case would still remain in the da's hands, the case is brought by fani willis and would remain that way, but if convicted and brought to trial and convicted, it would be subject to the same situation as the state case, where those convictions would not be able to be pardoned away. if would not be able to be pardoned awa . . , . , . would not be able to be pardoned awa. away. if it was in a state court, ou away. if it was in a state court, you would _ away. if it was in a state court, you would see _ away. if it was in a state court, you would see it _ away. if it was in a state court, you would see it as _ away. if it was in a state court, you would see it as well, - away. if it was in a state court, i you would see it as well, because they have television cameras, and you would not see as much in a federal court. as it was the questions that has to be settled when it comes to mark meadows is that whether he was acting in his capacity as white house chief of staff reaching out to white house officials or if he was acting as part of the trump campaign. what we hear about him as regards his responsibilities? i’m

hear about him as regards his responsibilities?— responsibilities? i'm here in washington. _ responsibilities? i'm here in washington, dc, _ responsibilities? i'm here in washington, dc, and - responsibilities? i'm here in washington, dc, and my . responsibilities? i'm here in - washington, dc, and my colleague is in court in atlanta. what we were expecting to see was something of a mini trial, and my colleague from messenger is providing updates on that. we are expecting to hear testament from the secretary of state in georgia, and the person on the infamous phone call where trump urged him to find 11,000, the number of votes that he needed to overturn the election results in the states. 50, thejudge the election results in the states. 50, the judge will hear the so, the judge will hear the evidence, and that will go straight to the central question, which is, as you mentioned, was mark meadows acting on his official capacity when he was serving as trump's chief of staff after the election? might like it should be said just before i let you go, these district attorneys are under a lot of pressure right now. we've got another under a lot of pressure right now. we've got anothe— under a lot of pressure right now. we've got another statements from the chair of — we've got another statements from the chair of the _ we've got another statements from the chair of the house _ we've got another statements from the chair of the house justice - the chair of the house justice

committee saying he is going to investigate fani willis to see whether he was in cahoots with the department ofjustice. the same thing happened with the manhattan district attorney. is that going anywhere? this investigation republicans are leading on the hill? i think one of the answers to those questions can be found in the fact that the hush money case is going ahead. the trial date might be moved, but that's not the function of the house judiciary moved, but that's not the function of the housejudiciary committee, thatis of the housejudiciary committee, that is a function of the fact that there was the setting of the trial date just today in dc that was in proximity of that. i think that what happens on the hill, we may find out the findings of the committee. i'm sure they will release whatever they learnt, but these cases, as we see, are moving ahead.— are moving ahead. good to talk to ou this are moving ahead. good to talk to you this evening, _ are moving ahead. good to talk to you this evening, thank— are moving ahead. good to talk to you this evening, thank you - are moving ahead. good to talk to you this evening, thank you very l you this evening, thank you very much. . ~ you this evening, thank you very much. . ,, i. ., you this evening, thank you very much. . ,, ., . around the world and across the uk. this is bbc news. let's look at some of the other

stories making headlines today. two people who died when a car was driven into a flooded area of liverpool have been named by merseyside police as married couple elaine and philip marco. the family said in a statement they were devastated and heartbroken. the couple were due to celebrate their 54th wedding anniversary next week. from midnight, london's ultra low emission zone will expand from an area covering the city centre, to the whole of the capital. it'll become the world's largest ultra low emission zone and means owners of the most polluting vehicles will have to pay £12.50 a day while driving in the area. and tens of thousands of people have been partying at the notting hill carnival. colourfully—costumed revellers paraded through the streets of west london for the annual celebration of caribbean culture and history. thousands paraded and danced along to dj sets as the annual two—day celebration reached its climax. you're live with bbc news.

fewer than 5% of thefts in england in the year to march, resulted in someone being charged. that may be down to a lack of evidence — but not always— there are plenty of reported instances where people have themselves tracked down a stolen bike or a mobile phone, maybe they caught the offender on a door bell camera, and yet when they reported it to police, nothing came of it. the home secretary says that's "completely unacceptable". she now wants all 43 forces in england and wales to follow up on evidence when there is a reasonable chance of catching an offender. the question is: do they have the resources? danny savage has more. with the rising popularity of doorbell cameras and dash cams, more crime is being recorded. couple that with googling for stuff that's been stolen from them, the expectation from victims is that surely it must be easier to catch those responsible. but that's not the reality. since 2015, forces have had to say

how many of the offences they record result in someone being charged. back then it was 16%, but now it's just under 6%. this morning's phone—in on bbc 5 live had plenty of callers sharing their experiences. so for quite a lot of anti—social behaviour you turn round, you ring the police, and that's as far as you get. we should be getting more to that system where people will know that if they commit a crime, there will be a definite punishment. we can't allow people i to get away with crimes like this and just walk away. there's far too many accounts from victims. .. the home secretary was in manchester today to flag up a reboot of basic policing in england and wales. every reasonable line of inquiry must now be followed up. if you are someone who depends on their car or their van for work purposes, having that stolen can put you out of business. if you've worked hard and, you know, you've had your possessions

burgled from your home, that can be incredibly violating. and we need to engender a better and more robust response from the police. the police federation, who represent the majority of officers, says they all want to do their best. they say this is actually about resources and that many officers are stretched beyond human limits. but what's the reality of officers being asked to follow up all reasonable leads on all crimes? something will have to give, and that's the concern. we have a tsunami of male sexual violence towards women and girls as it is. if the police are being told, you've just got to put even more resources into tackling, say, carand phone crime, that means there's going to be less time and less focus on those really serious violent offences that quite rightly the public are concerned about. labour has branded the new guidance as a staggering admission of 13 years of tory failure on policing and crime. with an election on the horizon,

expect to hear a lot more about policing policy. danny savage, bbc news, manchester. and we can speak now to richard garside, who wejust saw in mark's report. he is the director at the centre for crime and justice studies. thank you for sparing us some time. what you put the drop in crime is solved time to come up from 15% in 2015, down to 6%? to come out as a whole range of reasons. we did see a significant drop in the whole range of reasons. we did see a significant drop in th— significant drop in the number of olice, significant drop in the number of police. which — significant drop in the number of police, which the _ significant drop in the number of police, which the government i significant drop in the number of. police, which the government has significant drop in the number of- police, which the government has now started to address, but crime in many ways has become complicated, and we have also seen more focus in recent years, or the police are being encouraged to focus more on some of these really difficult things to sort out, child abuse,

terrorism, serious organised crime, male violence against women and girls. those take significant police resource, and one of the effects probably is a drop in the prosecution rate.- probably is a drop in the prosecution rate. probably is a drop in the rosecution rate. ., ., . prosecution rate. how do police rioritise prosecution rate. how do police prioritise if— prosecution rate. how do police prioritise if they _ prosecution rate. how do police prioritise if they have _ prosecution rate. how do police prioritise if they have limited i prioritise if they have limited resources? does it vary from force to force and what they focus on? it to force and what they focus on? it certainly can vary from force to force. one of the interesting things about what the home secretary said todayis about what the home secretary said today is that she wants the police today is that she wants the police to follow every reasonable line of inquiry. i suspect that a lot of police officers would say we already do that. i think the home secretary is effectively asking the police to just do what they already do, in which case, why make the call today? or, she thinks the police need to do a lot more. if that is the case, and if we are, for example, expecting the police to follow every single possible line of inquiry over every phone or stolen bicycle, then that

will have a significant impact on what police might be able to offer to devote to tackling pretty serious offences such as male sexual violence, child abuse, and other things the public rightly insist to be a priority. things the public rightly insist to be a priority-— things the public rightly insist to be a riori . . ., . , be a priority. there are some forces that have re-prioritised. _ be a priority. there are some forces that have re-prioritised. i— be a priority. there are some forces that have re-prioritised. i know - that have re—prioritised. i know manchester constabulary started to refocus on burglaries, and their solving rate for burglaries has been very good. so, if the sort of refocusing has been steered by the home secretary, it could work, could it not? �* , , ., home secretary, it could work, could it not? �* , i. . home secretary, it could work, could itnot?�* , . it not? i'm sure. if you are saying to the police. _ it not? i'm sure. if you are saying to the police, we _ it not? i'm sure. if you are saying to the police, we want _ it not? i'm sure. if you are saying to the police, we want you - it not? i'm sure. if you are saying to the police, we want you to - it not? i'm sure. if you are saying i to the police, we want you to really focus on burglary, for example, that i'm sure the police can have some impact on that. the question is what they are then not doing. only earlier this year, the government reissued new priorities for the police, national priorities, which included tackling child abuse, tackling male violence towards

women, tackling terrorism, tackling cyber crime. these are all very time sensitive and time demanding activities, and so, at some point, the police are going to have to make judgments about where they devote their resources. i think there is an issue here about the kind of messaging we're getting from the government. maybe in the run—up to a general election they feel they are potentially vulnerable in some of these issues, so they must reaffirm that. at the end of the day, there are only so many police officers, there is only so much time in the day, and therefore they can only focus on some things. if you say to them, can you focus on this, can you focus on that, at the end of the day they will say that will make for a challenging policing framework. goad challenging policing framework. good to talk to you. — challenging policing framework. good to talk to you, thank _ challenging policing framework. good to talk to you, thank you. the ukraine armed forces have reportedly bombed a russian airfield in kursk using a cardboard drone that is made in australia. the low cost expendable drones come flat—packed from down under. they can fly up to 120km and are capable of carrying bombs up to 5 kilos in weight.

and because they are made of cardboard they are practically invisible to russian air defences. the company is reported to have delivered the systems to ukraine in may. joining me now is jameyjacob, executive director, oklahoma aerospace institute for research and education. thank you very much being with us. tell me about these drones. how many of them do the ukrainians have, and how effective are they?— how effective are they? they've ordered them _ how effective are they? they've ordered them in _ how effective are they? they've ordered them in mass, - how effective are they? they've ordered them in mass, so - how effective are they? they'vei ordered them in mass, so there how effective are they? they've - ordered them in mass, so there are up ordered them in mass, so there are up to 100 at this point, but their effectiveness is really based on their low cost. they are made out of cardboard. not the car body would get with your amazon box, but coated with plastic, and it makes it very simple for them to get through. they can be assembled in the field using knives and rubber tape and bands to enhance the propeller, so it makes it very quick and inexpensive to get

them into the field. and it very quick and inexpensive to get them into the field.— them into the field. and what can ou them into the field. and what can you attach _ them into the field. and what can you attach to _ them into the field. and what can you attach to them? _ them into the field. and what can you attach to them? they - them into the field. and what can you attach to them? they can - them into the field. and what can you attach to them? they can be| them into the field. and what can - you attach to them? they can be used for a number — you attach to them? they can be used for a number effects, _ you attach to them? they can be used for a number effects, they _ you attach to them? they can be used for a number effects, they can - you attach to them? they can be used for a number effects, they can carry . for a number effects, they can carry a payload, they can be used for reconnaissance that transmits back to a ground station for surveillance purposes, they can be used to deliver non—lethal payloads, supplies from one troops to another trip, and they can also carry an explosive payload on board. there are also concerns _ explosive payload on board. there are also concerns about _ explosive payload on board. there are also concerns about the - explosive payload on board. there are also concerns about the supply of conventional weapons systems to ukraine, biggerweapons, but of conventional weapons systems to ukraine, bigger weapons, but what is remarkable about this war is how ukraine has used and adapted drone technology to really go far beyond its capabilities. this is another example of that, isn't it? it its capabilities. this is another example of that, isn't it? it is. this is not _ example of that, isn't it? it is. this is not really _ example of that, isn't it? it is. this is not really anything - example of that, isn't it? it is. | this is not really anything new. we've been utilising cardboard drones for years now, primarily for educational purposes and outreach to teach young children how to build aircraft and design the systems, but they have a number of applications

that they can use for a low—cost drone systems in other parts of the world which may not be able to afford the really expensive systems, because are cheap to deliver, to put in a certain location, and very inexpensive to assemble. things such as delivering medical supplies or emergency aid, or even for things such as weather surveillance, this really is a future application we will see in these types of drones. you work in research and education. does the advent of these sorts of drones, and the capabilities that they bring to the field, does that beg serious questions for military planners into the future? we had an example the other day where they blew an air defence system in crimea, a sophisticated defence installation, perhaps with one of these, who knows? does it beg questions about how useful conventional weapon systems can be, and whether they can be undermined by things like this?—

by things like this? certainly. obviously _ by things like this? certainly. obviously these _ by things like this? certainly. obviously these systems - by things like this? certainly. obviously these systems are | by things like this? certainly. - obviously these systems are being used in ukraine to deliver munitions. these can be used by terrorists or non—state actors as well. whether it is to deliver explosive devices or some kind of toxic, chemical, or drugs across borders, these low—cost systems can become really difficult to defend against, particularly in this case, because it is notjust the carboy that provides them with a low radar cost system, it is randall's way for ince so it is not emitting any frequency when it is fine. —— it is programmed with waypoints. hello. many of us had some very potent, heavy downpours to endure on saturday and sunday. monday's showers were, generally speaking, lighter in nature. now, tomorrow, there will be some showers once again, and actually, they could be set to turn heavier

as this cold front pushes its way southwards and eastwards. along the line of this weather front, we could see some very heavy downpours, maybe the odd thunderstorm. we'll see some of that heavy, thundery rain pushing its way south—eastwards across scotland overnight. some showery rain, too, into parts of northern ireland and northern england. ahead of that, quite a lot of cloud, but behind it, clear skies developing across much of scotland and northern ireland by dawn. so that means a mostly sunny start here as our band of showers pushes southwards and eastwards across england and wales. the showers tending to ease off for a time, but i think as we head into the afternoon and that showery rain gets down into the south—east corner, well, it could pep up once again. and at the same time, another band of heavy showers and the odd thunderstorm will push southwards across scotland. temperature—wise, we're looking at values between 15—21 degrees. and then as we move through tuesday evening, along the line of our cold front, we could see the odd thunderstorm in the south—east corner. our area of low pressure

still fairly close by on wednesday, so there will still be some showers, especially across northern and eastern parts of the uk. further south and west, more in the way of dry weather, some spells of sunshine before our next weather system begins to push in from the west. wednesday's temperatures generally between 15—20, maybe up to 21 degrees. now, as we move into thursday, we will see our next weather system running in from the atlantic. that will bring cloud and outbreaks of rain. there's uncertainty aboutjust how far north this rain may come. particularly it will affect southern parts of england, wales, the midlands, but we could see some rain into parts of northern england and northern ireland as well. much of scotland looks set to be dry with some spells of sunshine, and temperatures north to south 14—19, maybe up to 20 degrees. for the end of the week and certainly into the weekend, it looks like high pressure is going to try to build. now, there's a bit of uncertainty about this, about how strongly the high will build,

but there certainly are signs that as we move through the end of the week, into the weekend, we could see some drier weather.

hello, i'm christian fraser, and this is the context. we speak to dr martin luther king's family, 60 years after he stood on the steps of the lincoln memorial to deliver his famous

i have a dream speech. hello there. let's start with the us open, and it took the defending women's champion iga swiatek less than an hour to cruise into the second round earlier. the world number one from poland was untouchable, beating rebecca peterson with no trouble in her opening match at flushing meadows. it was easy work of the first set, swiatek winning that 6—0. the second almost as straightforward, 6—1, as she aims for a fifth grand slam title. swiatek faces daria saville next. there has been early shock to bring you, though. eighth seed maria sakkari is out.
