新中国的民航事业，从无到有，从小到大，走过了60年的风风雨雨，经过几代人的共同奋斗，取得了举世瞩目的成绩。这其中包含着无数民航人的辛勤汗水和满腔热血。

    我的爷爷是1958年从空军调入民航北京管理局所属航测大队工作的，这是新中国组建的第一支民用航空测绘大队。当时正值国民经济第一个五年计划时期，在党的“鼓足干劲、力争上游、多快好省地建设社会主义”总路线的指引下，在党中央关于民航工作要实现“两翼齐飞”的要求下，民航在完成传统航空运输任务的同时，迅速开拓了航空测绘（勘探石油、矿产）这一通用航空的新领域，以更好地服务于国民经济的发展。

    每当我与爷爷在一起聊天的时候，老人家经常情不自禁回忆起过去的那些岁月，我隐约感觉到他仿佛是沉浸在一种美好回忆的享受之中。

    刚成立航测飞行大队时，使用的都是当时苏联制造的飞机，由于工作性质的原因，一年四季几乎都是在外地工作，所去的地方主要在西南、西北、东北和内蒙古、新疆以及青藏高原，飞行工作和生活条件非常艰苦。每当外出执行任务时，除飞机本身安装测绘仪器外，还要携带帐篷、锅灶、简单交通工具和医务药品等。由于飞机小载重有限，经常是飞机载设备，地面人员则是坐火车、汽车，甚至畜力车前往基地。空中飞行几个小时，地面就要走上几天，经常几个月吃不到新鲜蔬菜。爷爷担任着领导工作，要经常下基层检查指导工作，有时要自带被褥和日常生活用品，来回需要几个月时间。就是这样的艰苦环境，丝毫没有影响他们这一代航空测绘人员的革命激情和乐观主义态度，因为他们心中时刻装着伟大的祖国。

    今天，跨越世界屋脊的青藏铁路的第一期工程，由青海省西宁至格尔木的路线就是上世纪70年代航测人驾驶着飞机飞出来的（当时还没有卫星遥感技术）。由于青藏高原海拔高，空气稀薄，含氧量低，没有高压锅，开水的沸点低，一日三餐吃的都是夹生饭，长期营养不良，再加上由于长时间在高原工作，许多人不同程度地患上了高原病。大家克服各种困难，积极地协助铁路勘探设计部门，圆满地完成了航空选线任务，为今天青藏线的全线通车开了一个好头。

    爷爷特别提到，上世纪60年代为了新中国国防事业发展的需要，他们在极其保密的情况下，进行了铀矿航空勘探工作。说着说着我忽然发现老人家的眼眶浸满了泪水，我问爷爷为什么流泪。他说，当时这种珍惜的铀矿都是在蕴藏在高山峡谷之中，航空勘探飞行线路中的地形、气象条件非常复杂，工作条件极端危险，飞机经常在峡谷中穿梭飞行，有时机翼两端离两侧山体只有十几米。当时的飞机没有现在高性能的电子设备，只有简单的雷达，在山间峡谷中飞行只能靠驾驶员的目测来完成，遇到突然变化的山区气象，只能摸索飞行，随时都存在着生命危险。我们航测人为了祖国的国防事业，发扬不怕苦、不怕死的大无畏精神，以英雄的胆略，为我国原子弹、氢弹的成功爆炸贡献出了自己力量，甚至是生命。

    这其中有些人因发生空难而牺牲，由于地理原因甚至连尸体都无法找到，他们长眠于高山峡谷之中。说到这里，爷爷哽咽了。他接着说，烈士们牺牲时有的才20多岁，还没有结婚，有的孩子刚刚出生就永远地失去了父亲。每当我代表组织处理这种空难事故善后工作时，看到烈士年老的父母、年轻的妻子和在襁褓中的婴儿时，无不心情沉痛。为了祖国社会主义经济建设的需要，为了祖国早日强大，作为新中国的航测人，他们义无反顾地登上飞机，翱翔于蓝天，把自己的一生献给祖国的民航测绘事业。

    爷爷最后语重心长地对我说，作为新一代民航人，你一定要弘扬老一代民航人无私无畏、勇于献身的崇高精神，珍惜自己的工作和生活环境，认认真真做人，踏踏实实做事，为我国民航事业作出自己的贡献。

New China's civil aviation business from scratch, from small to large, have gone through 60 years of ups and downs, through the joint efforts of several generations of people have achieved remarkable results. It includes countless people's hard work and sweat and the air filled with blood.

     My grandfather was in 1958 transferred from the Air Force, the Civil Aviation Authority-owned Beijing aerial work brigade, which formed the new China's first civil aviation mapping unit. That was when the national economy, the first Five-Year Plan period, the party's "go all out to strive for better and more economical to build socialism," the general line under the guidance of the CPC Central Committee on civil aviation to achieve the "fly with both wings," the request, the completion of the traditional civil aviation air transport tasks, while the rapid opening up of the aerial mapping (exploration for oil, minerals) This new field of general aviation in order to better serve the national economy.

     Whenever I chat with my grandfather when the old folks can not help but recall those past days, I can vaguely feel that he seems to be immersed in the enjoyment of being a kind of fond memories.

     Aerial flight, when the newly established unit, the use of all the then Soviet-made aircraft, due to the nature of work reasons, almost all working in the field throughout the year, the place to go mainly in the southwest, northwest, northeast and Inner Mongolia, Xinjiang and Qinghai-Tibet altitude, flight very difficult working and living conditions. Whenever out their duties, in addition to surveying and mapping equipment installed outside the aircraft itself, but also to carry tents, cookstoves, simple means of transport and medical pharmaceuticals. Load is limited due to the small aircraft, often flying airborne equipment, ground staff is train, car, and even animal-drawn vehicles to the base. Flight a few hours, the ground is necessary to go a few days, often less than a few months to eat fresh vegetables. Grandfather served as the leadership, should always check under the guidance of the grass-roots work, sometimes bring their own bedding and daily necessities, back and forth take several months. Is such a difficult environment, did not affect their generation aerial mapping personnel revolutionary fervor and optimism, because they are always filled with the hearts of the great motherland.

     Today, across the roof of the world the first phase of the Qinghai-Tibet railway from Xining to Golmud in Qinghai Province's line is that the last century 70's aerial to drive out of the aircraft (when no satellite remote sensing technology). As the Qinghai-Tibet Plateau high elevation and thin air, and oxygen content is low, there is no pressure cooker, the boiling point of water is low, eat three meals a day are half-cooked rice, long-term malnutrition, coupled with long hours working on the plateau due to many different levels to suffering from altitude sickness. We overcome the difficulties, and actively assist the exploration and design of the railway sector, the successful completion of the air line selection task, for today the full opening of the Qinghai-Tibet line, opened a good start.

     Grandpa special reference to the last century 60 years for new business development in China's national defense needs, they are in the most confidential circumstances, carried out uranium exploration work air. She spoke, I suddenly found that the elderly eyes soaked with tears, I asked Grandpa why the tears. He said the uranium was such a treasure hidden in the mountains and canyons are among the flight-line aerospace exploration of the terrain and weather conditions are very complicated and extremely dangerous working conditions, the aircraft often fly the shuttle in the valleys, and sometimes wing 2 side from both sides of the mountain is only 10 meters. At that time the plane did not present a high-performance electronic devices, only a simple radar, in the mountain valleys, to rely on the driver's visual flight to complete the mountain experience a sudden change in weather, the flight can only be explored at any time of life there dangerous. Our aerial survey were the cause of the motherland's defense, carry forward of fearing neither hardship nor death dauntless spirit, heroic courage, for China's atomic and hydrogen bomb explosions contribute the success of its own forces, and even life.

     This is because some of them happen at the expense of the crash, due to geographical reasons and even the bodies could not be found, they are buried in the valley among the mountains. Here, Grandpa was choked with sobs. He added that the martyrs who sacrifice some only 20 years old, not married, and some kids just born to lose his father forever. Whenever I crash on behalf of the organization to deal with such remedial work, see the martyrs elderly parents, young wife and the baby in swaddling clothes, are all feeling bitter. In order to China's socialist economic construction and the needs of the motherland at an early date in order to strong, as a new aerial survey of China, they hesitate to board the aircraft, flying in the sky, turning her life dedicated to the cause of the motherland's civil aviation mapping.

     Grandpa finally said to me in all earnestness, as a new generation of civil aviation people, you must carry forward the older generation of civil aviation were selfless courage of the noble spirit of dedication and cherish their own work and living environment, earnest man, a down-to work, in order to China's civil aviation industry to make its own contribution.
