flight recorders they could hold the key to revealing the cause of the crash and we can speak now to julian bray an aviation security expert hi julian much has been made of that video clip we saw that allegedly shows the airplane being hit how credible do you think that video is. i think we can say it's fairly credible because the supplier have been in court sourced it has done an awful lot of work on it so i would say on balance probabilities we should except that what about the focus of the investigation julian it was on to the black box flight recorders that were recovered from the crash site do we know if they were in good enough condition to be analyzed properly when i seen the pictures of the black vote flight recorders were delivered to a press conference this morning and they're in wooden crates there's some superficial damage on the data stack seems to be apart from the unit itself but i would imagine you should be able to get all the data rolls but it needs to go to an independent well resourced the bars 3 and holds good just frankly i don't think the rain or florence is has the expert

in bray he's an aviation security operations expert in london welcome to day devaney news africa julian is it really possible that this boy just walked onto the runway climbed onto a plane without anybody noticing this it's very very disturbing because i'm just so you see t.v. and they have actually discovered the c.c.t.v. and they have pictures of the poor little shop 14 years old like clinging on to the on the carriage before the plane took off. the point is that it's no use having c.c.t.v. if nobody is monitoring it and also because he shouldn't be on the anywhere near the apron it's all. so how often does defense like this happen we see it is a clear breach in security making these airports vulnerable to incidences like this how often do we actually see it happen. it does happen quite often but you have to remember there are hundreds of thousands of flights every day and it's all 24 hours a day and all around the world the tragedy is that only one in 6 days actually survives simply because they either freeze to death or they crushed by the on the carriage mechanism some people tried

this is a wheel comes out you will be squashed or you will simply freeze to death all right that's julian bray aviation expert in london thank you. president offered him last still reeling from the on for a fault from within its security forces that shut down parts office sydney's capital on tuesday and left at least 2 people dead the head of the country's transitional council saying his life has returned to normal but some locals believe that normal should mean a greater sense of security. a sound that would send anyone scurrying for cover a sound that has led to heightened fear and worry about sudan's volatile transitional government the country is in a 3 year transition to civilian rule. the gunfire on tuesday came in the midst of a mutiny by some members of sudan's much feared intelligence agency 9 months after the country's long time dictator omar al bashir was ousted during mass protests the agency was set up during bush years 30 year reign about 2 that doesn't as if you. let the you all follow the events of the day if you had which we feel very sorry about this you know it was only mean

back to the airport when the plane went down and discuss the crash with aviation security expert julian bray he says that the plane's black boxes should be deep coded as soon as possible as speculation is mounting nothing is off the table so it could well be a rocket strike missiles so it could have been shot down could have been a drone could have been. bird strike we don't know and that is why we have the black box flight recorders on board which sirree new ones have recovered and so since we can get these properly decoded then we'll all know exactly what has happened to this aircraft and it's very important that this is not for political reasons but for safety reasons and that is why it's terribly important that these boxes are decoded very quickly and if it means that we have to have a proxy policy in there looking after the interests of the various parties then so be it the point is we can't really delay the decoding of these boxes. and the best of it is look into possible causes of the crash family and friends of those killed are grieving and waiting for answers. him of and the right s

well let's get more on this from aviation analyst to julian bray he joins us from cambridge in the united kingdom welcome to d.w. so we have now an investigation and 3 pack conflicting theories iran's going with mechanical failure or pilot error while an increasing number of western intelligence agencies are pointing at an accidental iranian missile strike what are you thinking at this early stage. well the stories moved on quite a bit today and the the thinking is study it was a proximity missile basically this means at the misao is fire does not he touch the aircraft but soon see it comes within a few yards of it it will explode so that will then release lot so shrapnel and column 5 ish odds and literally it just lacerate see aircraft so that business is what the evidence seems me pointing to but we just heard from iran civil aviation had chief say that it definitely wasn't a missile strike what you think makes them so show well with the gray she's a respect to the a rainy an all thora sees they're not exactly a following procedure in investigating accidents they cleared the site they s

well let's get more on this from aviation analyst to julian bray he joins us from cambridge in the united kingdom welcome to d.w. so we have now an investigation and 3 track conflicting theories iran's going with mechanical failure or pilot error while an increasing number of western intelligence agencies are pointing out an accidental in the thinking is that it was a proximity missile basically this means that the missile is fine now if you touch the aircraft it comes within a few yards of it it will it's mode so that will then release not so shrapnel and carbon fiber shards and literally just lacerates the aircraft. so that this is what the evidence seems to be pointing to but we just heard from iran's civil aviation chief saying that it definitely wasn't a missile strike what do you think makes them so sure well with the graces of respect to the rain you know thora sees they're not exactly following procedure in investigating accidents they cleared the site they started clearing the site today they've had diggers out sort of moving everything away getting rid of all the day every there

we can't really delay the decoding of these boxes julian really appreciate your analysis as a bit more transparency to everything many thanks jim bray aviation security expert . thank you. now a preliminary a rainy and reports are just that the crew did not as we mentioned the radio for help but they were trying to turn back to the airport when the plane went down tehran as it will not and over the black box to the u.s. saw the plane make a boeing this is how the tragedy itself unfolded. more than 2 elk on the right side of the airplane and one end of it were completely on fire and i think the pilot made a great effort not to hold presidential hands it's the plane crash landed in largely park and destroyed the fence of a football then it took off again and exploded and was completely incinerated after what you know they didn't keep those watching the news of iranians hitting us bases with missiles on t.v. after 10 minutes i heard a massive explosion and all the houses started to shake there was fire everywhere at 1st i thought the american success truck here with missiles and i went into the basement to take cover all through while
