At around 1500 hours on 22 january, helium balloons in a view area of sichuan loshan city fell. On the evening of the same day, “lin soo wan” announced that four tourists had been injured, one had died as a result of hospital rescue and three had been treated in hospital。
On 23 march, liu shang, a 28-year-old hot balloon flight expert, told the newkyo newspaper journalist that “the regular helium balloons, with the exception of the main cable, have at least three protected cables on the ground to ensure that they do not drift away. At the same time, it should be equipped with a mandatory discharge valve fixed on the ground. Once helium balloons are removed from the cable, the valves will automatically pull open, and helium balloons will gradually breathe and slowly fall to the ground.”

Helium balloons are different from hot balloons
Some bloggers have posted ads on the web platform on the scene, “at the beginning of the year, the morning bird ticket + glass swing bridge was $19. 9 per person, and the top 20 air balloons are free of charge per day with tickets”
The accredited representative of the chinese civil aviation authority for the flight inspection of free balloons and the head of the chinese foreign aviation sports club, cheng peng, described the balloons in question as not a hot balloon。

"the balloon in the video is closed. It must be filled with gases less dense than air density, relying on gas lifts of less-than-air in a sealed ball bag. The tourists in the video are hanging under balloons, and if they were heat balloons, there would be a pod.” according to cheng peng, “there must be a burner flame under the shell of a regular balloon. A pilot with a civil aviation driver's licence produces buoyancy by heating up the air inside the ballbag by adding fire to it, so that the air density within it is less than the external air.”
The international air federation had classified thermal balloons as the safest vehicle. The rise and fall of the balloon and the altitude of the lift are controlled by the pilot and are therefore safer。
Regular manned helium balloons are expensive and flight requirements are stringent
A briefing on 22 january by shin soo-soo bay described it as a helium balloon. Liu shang stated that the regular helium balloons, in addition to the main cable, had at least three fixed protected cables. These four cables are fixed on the ground. Even if the main cable breaks, protecting the cable will keep the helium balloon flat. The helium balloon in the event ended up in a free-flying state。
On 1 october 2019, a helium balloon fell off a fixed steel cable in the ma jia poe district of yantai city, shandong province, and broke in the course of the lifting, resulting in the death of a mother and child. Pictures of this human helium balloon project on a tourism website
According to liu shang, regular helium balloons have forced vents that are fixed to the ground. Once helium balloons are removed from the cable, the vents will automatically pull open, and helium balloons will gradually breathe and slowly fall to the ground. Besides, there's a manual vent on the helium balloon。
Cheng peng states that the cost of a human helium balloon set is between $3 million and $7 million。
Liu shang is currently on a hot balloon flight in siem reap, cambodia, where helium balloons are known to be imported from france for a set of $7 million, capable of carrying 30 people at a time at a cost of $15 per person (approximately $101. 7 rmb)。
In september 2022, a worker in the forest yard of the town of haelin, the city of peon danjiang, in heilongjiang province, went up to over 10 metres in a hydrogen balloon to hit the pine tower. The hydrogen balloon suddenly went out of control, drifting at an altitude of more than 4000 metres for more than 10 hours and moving over 300 kilometres. Helium balloons purchased for the worker
According to the chinese association of industrial gases industries, more than 95 per cent of our existing helium is imported. Cheng peng described the high cost of helium as the world was under stress. Domestically, the price of a bottle of 40 litres of helium is over $2,000, and the price of the equivalent hydrogen content does not exceed $100. Helium balloons need about 100,000 yuan helium for their first inflating。
