    The use of aviation tools, except for origami airplanes, requires the joint efforts of a group of people, such as driving real airplanes, helicopters, and taking off hot air balloons.

    After all the hot air balloon equipment was ready, a group of four and a group of six began to work together quickly to piece it together.

    The first step was to spread the ball bag on the ground. They did this very quickly. It only took a group of four people about ten minutes to complete it.

    Another group of six people assemble the hanging basket. This one is more complicated because it needs to install the hanging basket shell, install the safety chamber, configure the burner and blower, etc.

    They are all well-trained veterans and finished the work almost at the same time. Then they worked together to connect the air bag to the hanging basket placed aside.

    At this time, the small engineering vehicle that followed the truck began to work, injecting helium into the deflated air bag on the ground.  Slowly, the air bag began to rise slowly, getting higher and higher, until it was five or six meters away, the blower in the hanging basket started to work, and the burner slowly sprayed fire out.

    The light gas and the hot air work together to speed up the rise of the hot air balloon. In this way, when the air bag takes off completely, the preparations are almost complete.

    Qin Shiou watched the hanging basket being hoisted swaying, feeling excited and said, "Can we go up now?"

    He looked at the time and saw that it didn¡¯t take long, less than an hour and a half. Moreover, this was the first time to take off. From now on, the gondola will be assembled. If there is no problem, the air bag will be inflated and it will be able to fly in an hour.

    Johnson shook his head and said: "No, Mr. Qin, we still need to debug the equipment. The GPS navigator, satellite phone, and radio station must be debugged one by one. If there are no problems, we will contact the ground support vehicle before we can take off."

    Qin Shiou said in astonishment: "Is it so complicated? When I read the introduction, didn't it say that two people can complete the takeoff of a hot air balloon?"

    The two people he mentioned are the pilots and co-pilots, who are used to control hot air balloons.

    Johnson shook his head and introduced to him: "Being able to take off and flying well are two different things! In the eyes of our professionals, a complete hot air balloon flight team has at least five people!"

    "So many?" Qin Daguan took a breath. He felt that it would not be easy for his hot air balloon to fly.

    Johnson continued: "Yes, there are quite a lot. First, we need two pilots and co-pilots, and secondly, we need two ground crew members, and a hygienist. If it is a special-shaped ball, it will be even more troublesome. The ground crew requires 9 people!"

    "Why do we need a hygienist?" Qin Daguan was helpless. He didn't introduce this when he checked the information.

    Johnson smiled and said: "Changes in flight altitude will cause changes in pressure, temperature, and air density, which will cause discomfort to people, so it is best to have a hygienist accompany you to monitor physiological data such as blood pressure, blood sugar, and blood lipids."

    After some testing, the engineer who came with Johnson gave him a thumbs up, meaning that there was nothing wrong with the hot air balloon and it was ready to fly.

    Qin Shiou asked: "Is it okay this time?"

    Johnson smiled and said: "Yes, it's okay, no problem at all."

    Qin Shiou nodded and took the lead in getting on the hot air balloon. There were two middle-aged men waiting inside. They were the pilots and co-pilots of this flight.

    Seeing Qin Shiou boarding the hot-air balloon openly, Johnson said: "Mr. Qin is really brave. Among the people I know, there are not many people who dare to go up in a hot-air balloon without trying it for the first time."

    Originally, when Qin Shiou bought the helicopter, the pilot piloted the helicopter several times by himself and then pulled Qin Shiou up after proving that there was no problem.

    But hot air balloons are different from helicopters. As long as you strictly abide by the hot air balloon operating rules, there will be no problems with this thing, because the rising power of the hot air balloon is the hot gas generated by the combustion of the combustion system. If the combustion system cannot produce hot gas, the balloon bag  It will become a parachute and fall naturally and slowly.

    Even if the airbag is broken, due to material reasons, as long as the airbag is not hit by a missile or torn apart by a tornado, it will not have a big gap all of a sudden. In this way, the burner will continuously produce hot air to supplement the gas leaking from the gap, and it can still be used.  Make sure the balloon lands properly.

    Of course, if there is no natural disaster or man-made disaster, but the balloon's air bag is broken and the burner cannot be used, then the people on it are indeed in danger, but the probability of encountering this situation is not much greater than winning a billion in the lottery.

    Now that hot air balloons have been certified by the International Air Transport Federation as the safest aircraft, Qin Shiou knows this, so what is there to be afraid of?

      In addition, the reason why Qin Shiou wanted to board the hot air balloon was not only out of curiosity, but also because he brought something - an extra-long banner that was rolled up and required him to hug it. This banner was to be hung on the hot air balloon.

    After getting on the hot air balloon, the two pilots started busy. One contacted the ground handling vehicle via radio, and the other checked the altimeter, elevation speed indicator, thermometer, pressure gauge, anemometer, etc.

    The burner began to increase the firepower, a super flame two to three meters long burned straight, powerful hot air rose, and the hot air balloon suddenly began to accelerate upward.

    Johnson explained to Qin Shiou: "We did not fill the helium enough, because the air bag needs to be given time to adapt to the tension when it is used for the first time, so this flight requires a burner."

    The fuel used by the Archangel F2 AM hot air balloon is propane and liquefied gas, and the burner is a high-energy compressed gas combustion furnace with a heating capacity 500 times more powerful than ordinary household gas furnaces. It can always maintain a fire and resist level 8 winds.

    If the burner fails, don¡¯t worry, there are two combustion systems on the hot air balloon that are on standby and can be turned on at any time.

    Now is actually not a good time to take off a hot air balloon. It is best to fly this thing when the sun has just risen or an hour or two before the sun sets. That is usually the time of day when the wind is calmest and the airflow is the most stable.

    The hot air balloon is not actually driven, it moves with the wind.  However, since wind has different directions and speeds at different altitudes, pilots can choose the appropriate altitude based on the direction required for flight.

    The wind is blowing from the north now, and Farewell Island is located directly south of St. Johns, so you can fly with confidence. This is why the pilot chose to take off now, otherwise the hot air balloon will need help if it wants to fly to Farewell Island.

    Qin Shiou used to be afraid of heights. He rode helicopters and aerial tractors in the fishing grounds every day. His fear of heights has been alleviated a lot. The hot air balloon didn't fly too high, so he could accept it.

    Flying in the air, he looked down and saw St. John's getting smaller and smaller under his feet.

    St. John's is a port city built on the seaside, so the terrain is uneven. There are many uphill and downhill slopes in the city, and some houses are built slightly tilted. This is especially clear when viewed from a height.  (Remember the website address: www.hlnovel.com
