由杰克·福斯特（Jack Fortune）主持，??由英国广播公司（BBC）发行的科学技术纪录片，作为1999年BBC地平线系列的一部分播出-英语旁白Science, Technology Documentary hosted by Jack Fortune and published by BBC broadcasted as part of BBC Horizon series in 1999 - English narration
------------------------------------------------------
1947年8月2日，一架英国战时的兰开斯特轰炸机轰炸机从布宜诺斯艾利斯机场起飞，飞往圣地亚哥。飞机上有5名机组人员和6名乘客-??名为“星尘”。但是星尘号从未到过圣地亚哥。取而代之的是，距地面只有几分钟的路程时，它消失了。最后发送了一个奇怪的摩尔斯电码无线电消息“ STENDEC”，但此后飞机上再也没有听到任何声音。尽管对安第斯山脉进行了大规模搜索，却未找到飞机的踪迹。53年来，失踪者的家人都不知道亲人发生了什么事，但今年早些时候，这架飞机突然重新出现在安第斯山脉高处的冰川上，距离上次报道飞机的地区超过50公里。今年2月，阿根廷军队安排了一次大型考察活动，参观了巨人图帕加托峰（6800m）下的坠机地点。他们的目的是带回在现场发现的人类遗骸，以便尝试识别它们。这次探险还为坠机调查人员提供了一个难得的机会，以了解他们是否最终能够解释这架命运多plane的飞机所发生的事情。“地平线”获得了此次探险的独家访问权，现在这是第一次“发生了什么事”的全文。可以说是“星尘”。为什么飞机在没有警告的情况下坠毁？为什么离计划的穿越山脉那么远？飞机发送的最后一个神秘信息“ STENDEC”是什么意思？的无线电运营商？撞车事故发生50年后，是否有可能识别出残骸的残骸，以图形方式证明了撞车事故中所涉及的可怕破坏力？也许最神秘的是，尽管多年来定期去图潘加托（Tupangato）进行登山旅行，但为何残骸却被遗忘了这么长时间？探险队加入了安第斯山麓的一个军事基地。高原反应和冬季来临的威胁意味着旅行需要精心计划。在为期四天的坠机之旅中，使用了100多个mu子，将人员和补给品运送到大本营，然后在冰川的一个高级营地上运送。在超过4500m的危险通道上，几只mu子掉落了。经过四天的艰苦跋涉，探险队终于到达了图潘加托冰川。他们有足够的补给品，可以使用36个小时来调查坠机现场，并最终解释星尘事件以及为何消失了这么长时间。在坠机现场，“地平线”跟随坠机调查人员，因为他对坠机的想法随每个新发现而改变。飞机的主轮被发现，但仍被炸毁。星尘号的劳斯莱斯发动机之一躺在冰上，附近是螺旋桨。螺旋桨损坏表明，坠机时发动机正常工作。残骸没有提供吸烟枪来解释这次事故发生的原因。发现了人类遗体-一只手，一半躯干的一部分埋在冰中，头发碎片-凄厉地提醒人们，这首先是一场人类悲剧。在布宜诺斯艾利斯的一个实验室里，科学家们仍在尝试从遗骸中提取足够的DNA以鉴定遗骸。那些与飞机一起坠落的人中，很少有足够大的孩子On August 2nd 1947, a British civilian version of the wartime Lancaster bomber took off from Buenos Aires airport on a scheduled flight to Santiago. There were 5 crew and 6 passengers on board the plane - named "Stardust". But Stardust never made it to Santiago. Instead it vanished when it was apparently just a few minutes from touchdown. One final strange morse code radio message - "STENDEC" - was sent, but after that nothing more was heard from the plane.Despite a massive search of the Andes mountains no trace of the plane was ever found. For 53 years the families of those who disappeared have not known what happened to their loved ones.But earlier this year the plane suddenly reappeared on a glacier high up in the Andes, more than 50 km's from the area where the plane was last reported. In February this year the Argentine army arranged a major expedition to visit the crash site beneath the massive Tupangato peak (6800m). Their aim was to bring back the human remains which had been found at the site, so that an attempt could be made at identifying them. The expedition also offered a unique opportunity for crash investigators to see if they could finally explain what happened to the ill-fated plane.'Horizon' gained exclusive access to this expedition, and now for the first time the full story of what happened to "Stardust" can be told. Why did the plane crash without warning? Why was it so far from its planned route across the mountains? What was the meaning of the last mysterious message - "STENDEC" - sent by the plane's radio operator? Would it be possible more than 50 years after the crash to identify the remaining fragments of human remains that so graphically testified to the horrific destructive forces involved in the crash? And perhaps most mysteriously, why did the wreckage elude discovery for so long, despite regular mountaineering trips to Tupangato over the years?The expedition was joined at an army base in the Andes foothills. The threat of altitude sickness and the approach of winter meant that the trip required meticulous planning. More than 100 mules were used on the four day journey to the crash site, ferrying people and supplies to base camp, and then on up to an advance camp on the glacier. Several mules fell on the perilous journey over a 4500m pass; others bolted.After four gruelling days the expedition finally reached the Tupangato glacier. They had enough supplies for 36 hours to investigate the crash site and finally explain what had happened to Stardust, and why it had disappeared for so long. At the crash site 'Horizon' followed the crash investigator as his ideas on the crash changed with each new discovery. The plane's main wheels were discovered, one still fully blown up. One of Stardust's Rolls Royce engines was lying on the ice, and nearby it's propeller. Damage to the propeller indicated that the engine was working normally at the time of the crash. The wreckage offered no smoking gun to explain why the crash happened.Human remains were discovered - a hand, parts of a torso half buried in ice, fragments of hair - poignant reminders that this was above all a human tragedy. At a lab in Buenos Aires scientists are still trying to extract sufficient DNA from the remains to allow the remains to be identified. Few of those who went down with the aircraft were old enough to have children, so DNA matches are being made with more distant relatives, further complicating the work. The difficult task of identifying the remains brought down from Tupangato is still underway.Meanwhile the air crash investigators focused on the mystery of why the plane had not been found for so many years. Their analysis led them to suspect that the reason the plane had remained hidden for so long could lie with the glacier the wreckage was lying on. As soon as they returned from the mountains the investigators visited a glacial specialist in Mendoza. He told them that if the plane had crashed on the upper part of the glacier it would have been gradually buried by year on year snowfall, until it became a part of the glacier itself. It would then have travelled downhill with the glacier under the influence of gravity. Eventually it reached a warmer zone, and here the ice started to melt. Gradually, out of the melting ice, came the remains of Stardust. The wreckage hadn't been found because for more than 50 years it had been buried inside the glacier.Stardust isn't the only plane to be buried inside a glacier. In Greenland an entire squadron of second world war aircraft which crash landed on top of the Greenland ice cap in 1942 were recently discovered a hundred metres under the ice. They too had been buried by years of snowfall which gradually hardened into ice, until planes and glacier became one.But having solved the mystery of why Stardust had disappeared for so long, much hard work remained - particularly trying to explain why the plane was more than 50 miles off course when it crashed. The Argentine investigation needed to explain why a highly experienced crew could make such a massive error. They focused on a meteorological phenomenon that was virtually unknown in 1947 - the 'jetstream'. This high altitude wind can blow at more than one hundred miles an hour. But in 1947 very few planes flew high enough to encounter the jetstream. Stardust was one of the exceptions.On the day of the flight bad weather over the Andes persuaded the crew to fly close to the plane's maximum altitude, so they could fly over the top of the weather and the mountains. Stardust's superior performance should have guaranteed it's safety. But in fact it was the decision to fly high that was at the root of the disaster. Unknown to the crew, they were flying straight into the jetstream. And because of the bad weather, they couldn't see the ground, so they had no way of knowing that the jetstream was dramatically slowing them down. It meant that although the crew's calculations showed they had crossed the Andes, in fact the jetstream's powerful wind meant they were still on the wrong side of the mountains. So when Stardust began it's descent, rather than being above Santiago airport, it was on a collision course with Mount Tupangato.The jetstream finally explained the reason for the massive navigation error, and therefore the crash. But the investigators were unable to explain one final mystery, the last radio message - Stendec - sent by Stardust just before the crash. Many explanations have been advanced, but to this day none has convincingly explained what the message meant. 'STENDEC' - Stardust's Final Mysterious Message
