The Sky Survey Eagle is constantly climbing, and Kyoto is getting smaller and smaller in sight. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

"Climb to 11,000 meters and turn into level flight!" Meng Yang gave instructions to the Sky Survey Eagle through Xiao Budian.

The Sky Survey Eagle climbed very fast, reaching its predetermined altitude in less than ten minutes, and when it looked down, the road on the ground was already faintly visible.

"Turn on the remote sensing system!"

With a command, the Sky Survey Eagle's body began to undergo subtle changes, and its belly began to flatten and unfold to form a shape that seemed to be recessed, and on the inner surface of this pot lid were tightly arranged small bumps, each of which was a receptor, and these receptors were connected in parallel to form a high-resolution passive sensing radar.

The picture flickered, and the remote sensing image of the Sky Survey Eagle was connected, and the entire field of vision changed, the city and roads disappeared completely, the vegetation on the surface also disappeared, and the deep and shallow layers of various colors appeared on the screen in a very three-dimensional image.

Under the remote sensing radar of the Sky Survey Eagle, the soil layer, rock layer, and underground river under the surface are clearly visible, and there are even various mineral layers in between.

"Adjust the receive band! From the ray band to the ultraviolet band, to the visible light, to the infrared band, to the microwave band, gradually reduce the frequency, all of them are tested. ”

As the test began, the picture began to become colorful, the geodetic remote sensing map of different bands kept flashing, the ray band had the worst penetration, and the intelligence received very vague surface features, as the band adjusted downward, the surface objects began to become clear, and then the image began to go deep into the ground, and the underground became clearer and deeper......

It was perfect!

Worthy of being produced by 9527, the remote sensing radar of Sky Survey Eagle can perfectly meet the needs of Mengyang and clearly outline the underground geological structure.

"Fly straight to the southwest mountains!"

When he woke up the next morning, the Sky Survey Eagle had already started its exploration work, and the geological structure of a mountainous area in a certain county had been placed in front of Meng Yang.

This is a mountainous area located in the northwest of Hubei Province, mostly rocky mountains, rich surface runoff, many mountains have suffered from the erosion of water flow, and there are many hollows and underground rivers in the mountains.

Meng Yang checked the past little by little, and found that the volume of these underground cavities was not large enough, and I was afraid that it would be difficult to meet the requirements.

"Where is Explorer 1?"

"On standby in the mountains of southwest Guizhou." Xiao Budian replied.

"Let the Sky Survey Eagle join the explorers."

Just after breakfast, the Sky Survey Eagle had already appeared in the sky above the mountainous area of southwest Guizhou, and some of the detection results had already come out.

Meng Yang himself studied paleontology, although he is not engaged in geology, but basically he has to deal with various rock formations frequently, and the basic concepts of geology are still there. The reflected waves of different rocks are different, and these differences are clearly identified through the detection images of the Sky Survey Eagle, and the differences in the underground rock formations can be clearly identified.

Meng Yang took a quick look, the mountainous geology here is more complex, with a large number of folds formed by plate tectonics, and the strata contain a large number of sedimentary rocks, and the content of igneous rocks is relatively small.

From the exploration imagery, it can be seen that this area was once an ocean, and the sedimentary rocks rich in the strata are basically marine sedimentary rocks, and the main components of these sedimentary rocks are biological carbonate rocks.

It is precisely because of this unique geological condition that the karst landform here has obvious characteristics. There are a large number of traces of erosion in carbonate rocks, and there are abundant traces of water flow and clarity in both underground and surface areas.

"Let the Sky Survey Eagle take this as the center of the circle, do a spiral involute flight, and thoroughly explore this area, I estimate that it is possible to find the large cavity we need under this mountainous area."

According to Meng Yang's instructions, the Sky Survey Eagle began to make detailed explorations around this mountainous area, and the data it sent back was immediately processed and spliced into a complete three-dimensional map of the underground geological structure.

Just as the Survey Eagle was on its work, a passenger plane flew past it.

"Mom! Mom! There's a bird in that! A child lying on the porthole watching the scenery suddenly shouted.

"Well, it's normal to have birds in the sky!" Mom was playing with her phone and said without raising her head.

"It's so big!"

"Well, it's normal for a bird in the sky to be bigger!"

"Mom, is that the Golden-winged Dapeng Bird, the one in Journey to the West?"

"That's a mythical story, and there is no golden-winged roc bird in reality."

"Mom, what kind of bird is it?"

"Flying birds!"

"Mom, Mom, look at it! Look what kind of bird that is! The child took his mother's arm and shook and shook and shook and annoyed his mother, so he had to lean his head and take a look.

"Probably an eagle, right?" Mom said uncertainly.

"Daddy! Father! Come and see, what a bird! Seeing that the mother was not good, the child began to be angry with the father.

Dad turned his head and looked, "I haven't seen it, this bird looks so strange." ”

As he spoke, Dad felt a little strange, "We're in the stratosphere now, and there are birds that can fly up at such a high place?" ”

As he spoke, Dad took out his mobile phone and took a few photos of the strange big bird, and posted them in the circle of friends.

When we found something strange in the stratosphere, our baby was stunned! ’

Not long after I posted it, someone left a message below.

The title party conquers the world, and the earth can't let go!

Identified, it's a bird!

After my careful argument, this is a big bird! The one with the feather, there is really a feather!

It's really stratosphere! Stratilayer clouds are clearly visible, so can a bird really fly up at an altitude of 10,000 meters?

Upstairs is lonely and unheard, what are the migratory birds that migrate across Mount Everest every year?

There are indeed birds that can fly up the stratosphere, which is not unusual, the question is that this bird looks so strange, and where was this photo taken?

Seeing this question, Dad replied directly: It should be over Guizhou Province at present.

The characteristics of this bird are strange, I have never seen this bird, so it is recommended to find an expert to take a look.

I'll go and turn it to the experts

Not a big deal, a very professional message was sent:

I found an expert in ornithology, and the expert looked at the photos and said that he had never seen this bird, and he needed to check the information and identify it carefully. The analysis of experts is as follows: there are many birds that can fly up the stratosphere, most of them are distributed in the falcon family, eagle family, duck family, and albatross family, and the wing form of this bird is biased towards the order Shearlands, but since it is over Guizhou Province, it should not be a seabird, and the seabird will not leave the ocean so far; Maybe it's a problem with the angle, but I always feel that the body shape of this bird is strange, and it would be nice if there was a higher resolution photo.
