Plane crash in China most likely due to bird strike. Can anyone make out what kind of plane it is ?

0:30 the dude was holding the toasted bird (hawk?) and says, "F-ing awesome! Little guy took down the plane." LOL How is that bird still alive?? I thought it had to have gotten sucked into the engine to take down the plane?

China tests new spy drones in near space ‘death zone’

High-altitude unmanned vehicles tasked with military intelligence gathering can fit inside a shoebox and cost just a few hundred yuan

High-altitude spy drones could help China dominate “near space” – a region of the Earth’s atmosphere that is at the heart of a modern-day space race.

Near space, which begins at about 20km above sea level, has until now been regarded a “death zone” for drones – thin air at this altitude makes it hard to generate lift, while extremely low temperatures mean electronic components like batteries are prone to fail.

However, a new type of Chinese-developed drone that is undergoing testing appears to have overcome such difficulties, marking a significant step towards China’s ambitions of exploiting near space for purposes of military intelligence.

Near space has long been seen as a promising frontier for intelligence services, but has remained relatively untapped because it is too high for most aeroplanes to operate, and too low for satellites.

The goal of scientists is to develop a durable near space vehicle capable of observing large areas for weeks, months or even years on end. Drones, which would cost just a fraction of what a satellite with comparable abilities would cost, are seen as one of the best ways of reaching that goal.

Until now, the Northrop Grumman RQ-4 Global Hawk, limited to an altitude of about 19km, has been the highest flying drone in use.

But last month, a research facility in Inner Mongolia successfully tested an experimental drone at an altitude of 25km.

The test involved two experimental unmanned aerial vehicles being sent up on a high pressure balloon before being deployed at different altitudes. The second drone was deployed at an altitude of 9km.

Each of the drones, which are about the size of a bat, was launched using an electromagnetic pulse that accelerated them from zero to 100km/h within a space about the length of an arm.

“It shot out like a bullet,” said Yang Yanchu, lead scientist of the project with the Academy of Optoelectronics at the Chinese Academy of Sciences in Beijing.

The drones then glided towards their targets more than 100km away, adjusting course and altitude in flight without human intervention. On-board sensors beamed data back to a ground station.

Significantly, throughout their flights, the drones barely left traces on radar due to their small size.

“The goal of our research is to launch hundreds of these drones in one shot, like letting loose a bee or ant colony,” Professor Yang said.

Similar test flights had been conducted by the US Navy and Nasa in recent years as America searched for a new weapon to penetrate air defence systems and gather sensitive intelligence behind enemy lines, he said.

At present, low-flying drone squadrons are vulnerable to dense anti-air fire, while current higher altitude models, such as the MQ-9 Reaper and China’s Caihong 5 series – that are still limited to altitudes of about 10km – each cost millions of US dollars.

The near space drones being developed by Yang’s team, on the other hand, are projected to cost as little as a few hundred yuan.

The drones are small enough to fit in a shoebox and weigh about the same as a soccer ball. They are made with composite materials and are designed to withstand the forces involved in electromagnetic launches.

The wings and body are blended into one flat, tailless fuselage to produce sufficient lift in the thin air. The sensors include a terrain mapping device and electromagnetic signal detector to locate military presence or activities.

But the drones would not carry cameras, Yang said, as the transmission of photo or video data over long distances requires bulky antenna unsuitable for near space launches.

Some models, including the early prototype tested in last month’s experiment, did not even have a power motor but would drift to their destinations as a glider would.

Yang Chunxin, a professor at the school of aeronautic science and engineering at Beihang University in Beijing, said there were still many challenges in developing high altitude drones.

“One of the biggest headaches is the near-vacuum environment, where electric currents can produce a spark. This can lead to shortages and damage electronic equipment,” he said.

“This is why high altitude drones are more difficult to build than lower-flying variants. Whether they can play a practical role in military operations remains an open question,” he said.

The high altitude drone is part of a project called the Scientific Experiment System of Near Space, a strategic pilot project of the Chinese Academy of Sciences.

Its development follows a 2013 experiment by Google, in which the internet company launched 30 high altitude balloons in the southern hemisphere to test their capability to relay internet data. Similar balloons launched by Nasa have stayed in near space for months.

Yang Yanchu said China was a latecomer in the race to near space, but the technical progress it had made in recent years was stronger than that of most other countries.

“We expect to achieve some major breakthroughs by 2020. They will be stepping stones towards massive applications,” he said.

In June, China Aerospace Science and Technology Corporation flew a large, solar-powered drone at an altitude of 20,000 metres for 15 hours.

The Caihong T4 aircraft, with a wing span of more than 45 metres, could be equipped with radar and communications equipment to provide early warning for Chinese military aircraft, according to state media reports.

Reporter: The famous test pilot Li Zhonghua of the Chinese PLA Air Force recently said on CCTV that many pilots have given their lives since the PLA Air Force was formed in November 1949. What do you think of this?

Fu Qianshao (An expert with the PLA Air Force): There is a standard to determine whether flight accidents are frequent. It's called flight incident rate/10k hours. This rate has been reduced from 0.2 or so to less than 0.1 in the Chinese PLA Air Force, which is very low even in comparison with those developed countries. Such a progress is attributed to the improvement of China's industrial capability and personnel competence.

It must be pointed out that accidents are unavoidable in warplane training, and an absolutely "safe" air force is most abnormal.

Given the warplane crash accidents happening in different countries in peacetime, the accident rate and crash rate always rise with the increase of training intensity, subject difficulty and confrontation intensity. If a country lowers the training standard and reduces flying frequency in order to achieve the "absolute safety", it will undermine real combat effect and lead to unimaginable consequences.

Chen Hong (A professor at the PLA Air Force Command Academy): In 2017, the Japanese Self-Defense Forces have had four major flight accidents, causing at least four deaths. This happened to the United States and Russia too. Incomplete statistics show that in the first 10 months of 2017, 12 planes have crashed in the U.S., and Russia also saw the crash of six main warplanes within 40 days from June this year.

Reporter: Real-combat training of both J-20 and carrier-based fighter jets will be more frequent. What measures should be taken to avoid training accidents as much as possible?

Fu Qianshao: As I said, it's hard to absolutely avoid training accidents, but the accident itself is a kind of warning and it urges the military to make further improvements in equipment and training reform.

To be more specific, we need to develop new trainer jets and improve training quality. Practice proves that trainer jets with exceptional performance can not only ensure flight training quality, but also play an important role in guaranteeing pilot safety.

Therefore, China has put forth a number of advanced new trainer jets in recent years, such as the FTC-2000 Mountain Eagle and JL-10. They have been commissioned the PLA Air Force on a large scale and are mainly used to foster Gen-3 and Gen-4 warplane pilots, which is helpful for improving training quality for Chinese pilots.

The great difficulty in training warplane pilots is the complexity of the Air Force's flying training system. Generally speaking, flight training consists of two parts - skill training and combat training, the former training the pilots' plane operation capability and the latter training their combat capability.

Different trainer jets are used in different training stages. For instance, for pilot selection and primary flight training in aviation colleges and flying academies, the CJ-6 primary trainer jet is the main model, while JL-8 is used for basic flight training at the middle level and in some advanced training. At present, advanced flight training of the PLA Air Force is mainly carried out by JJ-7, but the more advanced JL-9 and JL-10 will be used in the future.

Usually when a flying cadet graduates from the aviation academy, he becomes a qualified pilot, but he cannot fly the warplane yet. Only after he completes the training on trainer jets of the same model as the warplane at the aviation troop or training base will he become a real pilot who can fly fighter jets.

At the moment, the PLA Air Force is reforming its training system and training plane system in order to catch up with development and meet combat demand. An important aspect of the reform is adjusting the trainer jet system to be more scientific and rational, and another aspect is to upgrade the systems on some trainer jets, so they can simulate operation and use features of Gen-3 and Gen-4 fighters.

For instance, adding the satellite navigation system, HUD and multi-function display can familiarize the pilots with the cabin interface and operating habits of modern warplanes as early as possible, laying a solid foundation for avoiding training risks and intensifying tactical training.

Reporter: In November 2016, Yu Xu, the first female J-10 fighter jet pilot in China, died in a training flight, drawing extensive attention from society. Can you tell us about the development of female pilots in the PLA Air Force?

Chen Hong: There have been more than 500 female pilots in China since 1949, some of whom are retired. Fewer than 100 female pilots are serving in the PLA Air Force today.

China had its first batch of female warplane pilots in April 2009. Yu Xu was one of them, and she was also the first J-10 female pilot. They mainly flew the J-10 and JH-7.

General female pilots that we recruited in the past mainly flew military transport planes, or served air duty on the plane. But female warplane pilots today are different.

The PLA Air Force has begun to train female warplane pilots because they are more detail-oriented and thorough and have advantages in using precision equipment and identifying terrain.

Reporter: We noticed that the Chinese military has become more open and transparent in dealing with emergencies in the past two years. What does that mean?

Chen Hong: The Chinese military has indeed become more transparent in the past few years, which indicates China's growing strength in national defense.

As a matter of fact, increasing the military's openness and transparency is an important way of "deepening trust and dismissing doubts". It will help other countries in the world to have a correct perception of the Chinese military, and it also reflects China's sincerity in conducting foreign cooperation in military security and its wish to voluntarily increase military transparency.
