Helium balloons must be used to release large balloons. Every city has different standards for flying large balloons, and now some cities are more strict in reviewing such large balloons. It is forbidden to fly near the airport, and it is generally impossible to audit flights in crowded places. There are several audit departments, and the procedures are complicated. At present, most of the big balloons released on the market are smuggled and illegally operated, and there is nothing wrong with them. If something happens, it will be unlucky, and the penalty will be thousands to tens of thousands. Seriously injured, that's even more serious. The hydrogen balloon stained with rain did not fly very high, but landed slowly in the streets of the city, even on various traffic fortresses on land, sea and air.
Note: It is illegal to release balloons without permission.
The "flying" hydrogen balloon floating in the air is really beautiful, but many citizens may not know that the danger brought by this behavior will come at any time. In recent years, reports about serious accidents caused by the illegal release of hydrogen balloons and the closure of airports and flight delays caused by balloon floating in some airports have appeared in newspapers from time to time. For example, the balloon explosion accident in Yiwu and the fatal accident caused by the balloon falling off in Pingtan County. Just around us, there have also been accidents of illegally releasing hydrogen balloons, such as the explosion of Dongshi balloon in Jinjiang. After the hydrogen balloon is released, once it falls off, it will float high in the air. Sometimes the released hydrogen balloon looks solid, but if it encounters strong wind, it will easily fall off, which seriously affects the safety of aviation flight. The relevant person in charge of the Municipal Meteorological Bureau told the reporter. It is understood that the Municipal Meteorological Bureau receives many notices from aviation departments every year, all of which are related to the fact that hydrogen balloons float and planes cannot fly normally.
