In this regard, Yuan Fang didn't feel anything wrong at all, knowing people and making good use of them is the principle he has always emphasized and implemented, since Ji Yu has this ability, then he should be allowed to play to his heart's content, this is also a kind of exercise, a means of tapping talents, no matter what others say, anyway, after many years, Ji Yu himself agrees with this very much.

As the sky gradually brightened, the trainees arrived one after another, and many of them came directly without eating, which shows how eager everyone is looking forward to the flight.

The doors of the twenty hangars were opened, and the trainees assigned to the ground service department carried out the last inspection and then pushed the mobile landing platform to move the fog balloons and airships out of the warehouse, and on the apron, three airships, five reconnaissance boats, and twelve fog balloons were neatly lined up, and they entered the take-off field one by one under the command of Jiyu.

This process sounds simple, but in fact there is an unknown secret, not very to say that the fog balloon and the airship can be casually pushed to the set position, the ground crew must check the distance between each other, according to the day's wind speed, weather, air pressure to adjust the distance between each other, to avoid collision and crash during liftoff.

Crash, everyone has heard of this term, but it is still unfamiliar, for so long, no one has ever seen what the real crash looks like, only Yuan Fang has been emphasizing safety and the lethality of the crash, the only thing that involves the crash and everyone knows that there is only one, that is, the parachute, which is a batch of life-saving materials that has only arrived in recent days, and it is also the life support of the Air Force.

The parachute is something that Yuan Fang made when he was in the imperial capital scientific research base, in fact, this thing is not complicated, and the internal parachute opener is somewhat difficult, the folding method and practicality are fixed, as long as the workmanship is passed, it can generally be deployed, which is the result of many times of practice in the imperial capital scientific research base.

The umbrella is made of a mixture of silk and dense surface cloth, which has quite good toughness and wind resistance, but the technology is not mature, the time is limited, in order to pursue stability, the umbrella is still a little large, the resistance is slightly stronger, the speed of descent is a little slow, and the air is affected by factors such as wind and gravity, but it can still play a life-saving role at a critical moment, so the empire is the first time to catch up and equip the air force at any cost.

When it comes to parachutes, you can't help but think of paratroopers, Yuan Fang is no exception, but think about it, the paratroopers are almost useless in this world, not to say the tactical role of paratroopers, but the actual operation, the air force's aircraft are either fog balloons or airships, all have the ability to rise and fall vertically, the task of transporting troops to behind enemy lines or other important positions, the landing conditions of transport airships are not high, no runway is required, a small piece of open space can be done, and the general geographical environment can basically be realized, so paratroopers have no meaning.

Today's whole day is a flight practice class, first of all, starting with the female soldiers, from the warehouse, stopping, inspection, boarding, lift-off, one by one, Yuan Fang, Ji Yu and several technicians from the scientific research base are responsible for supervising, judging and guiding improvements.

Twenty aircraft, etc., why twenty and not thirty, because the other two airships, the fog balloon, and the dinghy were either dismantled into teaching models, or were on patrol reconnaissance missions in the nearby seas.

The female soldiers boarded the airships or fog balloons under the leadership of the captains, and the best students boarded the only three reconnaissance boats.

From the operational point of view, the operation difficulty of the boat is greater than that of the airship or the fog balloon, the airship is huge, and what is needed is effective command and cooperation, the fog balloon, the operation is relatively simple, but it also requires a clear mind and adaptability, while the boat is not, according to the conventional configuration, a small boat only has one driver and one maintenance two, because of the fast speed and the hypothetical enemy air reconnaissance boat, so the control technology and reaction ability and the critical decision and so on are higher, especially for bad conditions such as thunderstorms, strong winds, Weather conditions such as weather responses and forecasts, etc.

Fog stone, for these students is no longer strange, no longer mysterious, everyone has seen the appearance and basic characteristics of the fog stone, and knows more about the approximate energy that a fog stone can produce, but the fog stone used here is a processed fog stone, has been unrecognizable, even if these people really encounter a fog stone mine in a certain place, they may not be able to recognize.

Fog stone, as the main energy source of the Imperial Air Force, is not one of them, it is the focus of protection, it is allocated by a special person, and the use and consumption of the device must be sorted out in the register, reported for backup, and here, the important resource of fog stone is naturally in charge of Yuan Fang, of course, this goods will not be honestly a custodian, these things, unexpectedly thrown to Sang Rou and them to deal with.

Let's talk about fog stone, this thing is really amazing, its weight is much lighter than air, much lighter than hydrogen, ammonia, etc., let's put it this way, if the airbag of the hot air balloon on the earth needs to be twenty-one meters high, the diameter of the sphere is eighteen meters, according to the performance of the fog, the airbag can be reduced to one-fifth under the condition of keeping the load unchanged, but that will affect the balance and stability of the fog balloon, so Yuan Fang will shrink it to almost half of the appearance, plus the counterweight, to reach a balance point, that is, it looks a bit different, Take the fog balloon as an example, the airbag is not much bigger than the hanging basket, which makes Yuan Fang feel unpleasant to see it, but it is perfect in the eyes of others, which should belong to the visual discomfort caused by preconceived subjective differences.

The flight lesson is carried out in an orderly manner, led by the 'master' who has flown before, all the students board, under the guidance of the masters, the students do the last check before take-off in accordance with the regulations, whether the rope is secure, whether the pulley is stable, whether the airbag is complete, whether the gondola is explained, etc.

Everything was ready, and the reconnaissance dinghy began to take off, because the pilots of the reconnaissance dinghy were all trainees with a certain amount of experience, and there was nothing abnormal during the take-off, and they flew into the sky, and under the command of the long plane, they worked hard to form a triangular formation and surround the surroundings for vigilance and reconnaissance.

Then, there were the fog balloons, which shook slightly, but fortunately, they all took off smoothly and suspended in the sky.

Finally, there is the airship, Yuan Fang named the flagship he was riding on, the Great White Shark, at this time, he stayed inside, but he didn't do anything, just sat in the cabin and looked out the window with a small bottle of hot water, Sang Rou and the others were very busy.

The Great White Shark rose smoothly, Sang Rou, who was in charge of the helm, was red with excitement, and after a burst of cheers from the others, they hurriedly returned to everyone under the reprimand of the guide, Yu Jingqiu, who was in charge of the command, had a calm expression, and it was unknown what was going on in his heart.
