The pilot was flying too low and too slow. A vintage jet performing a loop the loops stand crashed onto the a27 in 2015. In theirfinal report into the incident in 2015 in which a vintage jet performing a stunt crashed onto the a27 the investigators said the pilot started the loop stunt too low and too slow and could have taken action to abort the display. Our correspondent Duncan Kennedy reports. This was the Hawker Hunter jet at the centre of the Shoreham Air Crash. This is the jet over the shoreham area the day of the accident. It was during one manoeuvre that this happened. Thejet during one manoeuvre that this happened. The jet crashed during one manoeuvre that this happened. Thejet crashed by during one manoeuvre that this happened. The jet crashed by the a27 that ran alongside the showground. 0h, that ran alongside the showground. Oh, my god the fireball engulfed drivers and bystanders. A disaster measured in seconds and gave little chance of escape. Ii measured in seconds and gave little chance of escape. 11 men were killed, it was the worst Airshow Accident in britain in more than 60 yea rs. Accident in britain in more than 60 years. Among those who died was marked weaves, a plane enthusiast. His family today gave their reaction to the Accident Report. Obviously, the aib were brought in to discover the aib were brought in to discover the cause of the crash based on fa ct, the cause of the crash based on fact, they were not there to attribute blame and they have determined the cause. In that sense, we are satisfied, but obviously, it has exposed a lot of key flaws in the running of their shows. Air Accident Investigators produced this video today of what they say happened. They say the pilot was lower than he should have been at the start of the manoeuvre and there was not enough Engine Thrust or speed. The aircraft was too low to perform the loop the loop and it may be the pilot mis read his height instruments. He hit the ground. Investigators will not save the crash was avoidable but that a number of factors combined to cause it. And escape manoeuvre was possible and could have been conducted by the aircraft but with some additional work, we found there are all sorts of Human Performance limitations that might have prevented the pilot from recognising he was too low all that and escape manoeuvre was necessary or possible from that position. The pilot of the jet was andy hill, he survived with serious injuries but has no memory of the crash. The report suggests he may have confused his speed and altitude with other aircraft he had flown. The report also found there we re flown. The report also found there were deficiencies of organisation and maintenance. The aircraft was not complied with its permit to fly. There was a lack of clarity over who at the airshow was responsible for safety. Controls to protect the public were ineffective. The Civil Aviation authority which governs safety at britains air displays has already brought in a number of changes following this crash. Increasing the distance between the display and the crowds watching below and also requires pilots to be Better Qualified before carrying out these acrobatic manoeuvres. Todays final Accident Report has answered the technical question of what and why this crash happened. And that may give some measure of understanding and comfort to the relatives and friends of those who died. And duncan is in farnborough so duncan What Happens Next . Essentially, all the interested parties take away this report and absorb it. Its very long and complicated, not least of course for the families and their solicitors. This report was not about apportioning blame, but finding out what happened, and what happened was that this plane was flying too low and too slowly. The report also concludes there were other contributing factors with the pilot and the plane and the organisers. Going forward, what happens, the Police Investigation into the pilot andy hill, now continues. They have already questioned him under caution and they will now consider whether he should face Manslaughter Charges oi he should face Manslaughter Charges or not. One final thing is that the inquest can now go ahead. The coroner was waiting for this Accident Report to be published and that has now happened so a date for the inquest is now expected. That also should give some comfort to the families of the shoreham Airshow Disaster. Theresa may has attacked the snp, saying it is obsessed with independence regardless of fact and reality. Speaking at the Scottish Conservative conference in glasgow, the Prime Minister accused the Scottish Government of neglecting and mismanaging Public Services in scotland and said it was the poorest and most vulnerable who benefited most from the union between scotland and the rest of the uk. Lorna gordon is in glasgow lorna its the first time she has addressed the conference as pm and theresa may did not pull her punches this was a very wide ranging speech the Prime Minister gave and there was a positive message about the union and the shared history but what was most striking is that she came out swinging. She used quite Strong Language in what was an aggressive attack on the snp, focusing in part on their policies at holyrood and on their constitutional position. She said they were a Party Interested in stoking up what she called endless constitutional grievances, a party focused on just one thing, independence, to the detriment of the dayjob, independence, to the detriment of the day job, delivering independence, to the detriment of the dayjob, delivering devolved areas of policy like health and education. Politics is not a game, and government is not a platform from which to pursue constitutional obsessions. It is about taking the serious decisions to improve peoples lives. A Tunnel Vision Nationalism which focuses only on independence at any cost sells scotland short. Applause those comments are provoked a response from the snp, who have their own conference in a fortnights time. Angus robertson, deputy leader of the snp, causing the comments, ironical, hypocritical and surreal. He said he believed it was theresa mays governments constitutional obsession with a hard brexit which is threatening scottish jobs and livelihood and that she was guilty of mind boggling hypocrisy. Theresa may might have been wanting to shut down the debate over independence ahead of starting those negotiations over brexit, but i think if anything, the language is heartening on both sides of this debate over independence and the rhetoric is ramping up. Police who investigated the sudden death of a baby in cumbria have been heavily criticised as being disorganised and having an unstructured approach. Poppi worthington who was just 13 months old, collapsed at her home in Barrow In Furness in december in 2012. The independent Police ComplaintsCommission Found that the investigation into her death was not fit for purpose. Judith moritz reports. Poppi worthington only lived for 13 months. She was found with serious injuries at her home in barritt in 2012. The investigation which followed her death was so flawed that four years on, serious failings are still coming to light. The watchdog, the ipcc, has published a Report Levelling heavy criticism at cumbria police. The investigator found evidence there had been an u Nstru Ctu Red found evidence there had been an unstructured investigation, essentially not fit for purpose. We found concerns in relation to the way that the scene where poppi had been was managed. The reports details are a catalogue of mistakes made by detectives. Crucial evidence was thrown away. Witnesses were not interviewed for eight months. There was enough evidence to arrest poppis father on day 1. But Paul Worthington has never faced poppis father on day 1. But Paul Worthington has neverfaced charges although a High Courtjudge ruled he had probably sexually assaulted his daughter shortly before her death. He has always denied this. For most people, this is incomprehensible that the father was not investigated immediately. By the time the trail was picked up, it had gone cold and so was picked up, it had gone cold and so probably, there will never be justice for Poppi Worthington and thatis justice for Poppi Worthington and that is a terrible thing. The ipcc found that two detectives who led the investigation had cases to a Nswer The Investigation had cases to answer for the investigation had cases to a nswer for gross the investigation had cases to answer for gross misconduct. Both are now retired. They waited until they got a firm report by the pathologist with firm conclusions. That took seven months and in that seven months, the whole investigation went into suspended animation. That was wholly unacceptable because that was seven months lost. A new inquest will be held in may and poppis mother says that the failings have left her deeply and profoundly distressed. Donald trump has defended his Attorney GeneralJeff Sessions as an honest man and dismissed calls for his resignation. Senior us democrats have demanded the Attorney General step down, saying he had lied on oath at his Confirmation Hearing over his contacts with the russian ambassador. President trump said mr sessions could have stated his response more accurately but it was clearly not intentional and accused the democrats of a witch hunt. Daniel boettcher reports. At the centre of the latest allegations of contact between the Trump Administration and russia, the Attorney GeneralJeff Sessions. At his Confirmation Hearing, hed failed to tell the senate about two meetings with the russian ambassador. Senior democrats accuse him of lying under oath. President trump says he still has his full confidence. Jeff sessions has resisted pressure to resign, but he has now removed himself from any investigations looking into the election campaign, including allegations of russian interference. The reason i believed i should recuse myself is because i was involved in the campaign. To a degree, i think it would have been perceived but i wouldnt have been objective in participating in an investigation that might involve the campaign. I did not confirm or deny any investigation. I just felt like i should clear the air. SenatorJeff Sessions but hes denied he did anything wrong, and describes whats been said about his meeting with the ambassador as unfair and hyped beyond reason. President trump has come to his defence, tweeting Jeff Sessions is an honest man. The real story is all the illegal leaks of classified and other information. It is a total witch hunt. This is russias ambassador to the us, sergey kislyak. Its a post he is held for almost a decade. There has been a furious response from russia to allegations in some us news reports that he is a spy. The Foreign Ministry describing it as a Media Provocation and a stunning charge. And when russias Foreign Minister was asked today about the continuing controversy over his Ambassador MeetingJeff Sessions, his reply echoed words President Trump had used earlier. Translation i can only quote the phrase that has appeared in the media today. Saying that all this closely resembles a witch hunt. 0r times of mccarthyism, which we thought had long passed in a civilised country like the us. But more contacts have emerged. Mr trumps son in law and senior adviser, jared kushner, was with michael flynn, who has since been sacked as National Security adviser, when he met ambassador kislyak after the election. Daniel boettcher, bbc news. 0ur correspondentjane 0brien is in washington. Has the president and mr sessions done enough to make sure this goes away . For now, ithink, but the democrats are still circling. I think hes done enough to appease some republicans who were worried about what a distraction this was becoming. By taking himself out of this investigations into allegations of russian interference into the election, he has quietened things down for the moment. Ultimately, this is all about transparency and people simply dont know who met whom, when, what the conversations we re whom, when, what the conversations were about and this is the problem facing the Trump Administration, because its very difficult to prove a negative. Its very difficult to prove these conversations were innocent, that nothing happened, because people simply dont know. The more these revelations keep coming up that yes, senior officials like the Attorney General did have contacts with russian officials, then the more it looks bad. Thank you. The time isjust after quarter past one. Our top this lunchtime pilot errors caused the Shoreham Air Crash which killed 11 men. The final report says the stunt was perfomed too low and too slow.

Counting is under way for Northern Irelands Assembly election vote. Polls closed last night, with final results expected on saturday afternoon. Its the second time that Northern Ireland has had to choose a government in the space of ten months. Chris buckler reports from belfast. This generation might not remember the troubles, but elections in Northern Ireland tend to expose all divisions, and once the results of this vote are known, the challenge could be Holding Onto Power sharing. The public seem to have been engaged by this campaign. Turnout is up. But a new government at stormont doesntjust depend on the results. It needs the parties to agree to enter into a coalition together again. At one stage last year, sinn fein and dup seemed so close that their leaders, Martin Mcguinness and arlene foster, were given thejoint nickname of marlene. But that cosy relationship didnt last long. The Coalition Government collapsed at the start of this year after a series of rows, not least over a financial scandal connected to the rhi, the renewable heat incentive, a botched Green Energy Scheme that was at one stage rejected to cost the taxpayer around half £1 billion. That led to what felt like quite a divisive and at times bad tempered election campaign, but once the final votes are counted, the parties will immediately have to start thinking about negotiations to try to get Power Sharing and stormont back up and running again. Here in our virtual assembly, we can see how the parties did in the last election, which was, remember, less than a year ago. Then, the dup won 38 of the 108 seats, while sinn fein were in second place with 20 Assembly Members. The Oppo
