Because Europe is a hub that spans many countries, they have to go through Europe to get to the United States.
-
I think it's because Europe is an intermediary for them, so they have to pass through.
-
It may be because of some agreement between them, or because of the geographical location.
-
This is mainly because it is a transit station, so it is like this.
-
It is because Australia is a relatively large transit station, which is a little more convenient.
-
Because after going to the United States, they used different situations, so they said that this is the case.
-
At that time, Europe and the United States were connected, so they said this.
-
Who told you about it, it may be the problem of this route, but it is definitely not the whole story.

The United States and China are basically at the same latitude, and there is only a Pacific Ocean between the two countries, so it stands to reason that if you want to fly from Beijing to New York, you can go directly to the east by plane, and you can reach the United States by flying through the North Pacific. However, the map is only flat, and the earth is round, and in real life, the nearest route from China to the United States is not to go straight to the east, but to the north.
That's right, go directly north, cross the eastern part of Mongolia, Siberia in Russia, the Arctic Ocean, Canada, and finally reach the east coast of the United States, which is the closest route from Beijing to New York. Although this route is the closest and most time- and fuel-efficient route, the Kremlin has always refused to open Siberian airspace from the Soviet Union to Russia, and no aircraft can enter Siberia without permission, otherwise the Soviet or Russian air forces will not hesitate to shoot down incoming aircraft, even if it is only a civilian airliner.
Therefore, in the actual flight, the civil airliner has to bypass Russia, fly along the eastern edge of Siberia, pass through Alaska and Canada in the United States, and then fly to New York. Although this route is much farther than a direct flight to the North Pole, it is much closer than a transpacific flight. It's just that when flying this route, it is necessary to pay more attention and not to invade Russian airspace, otherwise Russia will respond with missiles.
Historically, the Soviet Union has shot down civilian airliners entering Siberia.
After that, the United States ** also further opened up some of the GPS system functions to the private use. Moreover, the United States has been urging Russia to open Siberian airspace to civil aviation companies, but Russia still refuses to open Siberian airspace. To this day, Siberia is still an insurmountable forbidden place for civil aviation companies of various countries.
-
Because there are few supply depots flying directly from the Pacific Ocean to the middle of the United States, it has to pass through Europe.
-
Because it's safer to fly to Europe, or it's closer to that side.
-
It's so good, of course, there must be a route, this is the route regulations, there is no why.
-
Because that's what international aviation does, it's too dangerous in the Pacific.
-
Because this is the only way to go, you can only get to the United States by going through Europe.
-
Because the route is set, or maybe you want to go to the transfer station to refuel.
-
Because this thing has a direct relationship with their own situation.

Summary. Hello dear! Yes, you can.
Hello dear! Yes, you can.
Hello dear! According to the official announcement of the United States on January 25, 2021, foreign travelers who have traveled to the following countries in the 14 days prior to entering the United States will be barred from entering the United States
South Africa; Brazil; United Kingdom of Great Britain and Northern Ireland, excluding Overseas Territories outside Europe; Ireland; 26 Schengen countries (Austria, Belgium, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden and Switzerland); Iran; The People's Republic of China, except the Hong Kong and Macau Special Administrative Regions. Certain family members of U.S. lawful permanent residents, U.S. citizens and lawful permanent residents, as well as other exceptions listed in the declaration, are exempt from entry restrictions. Based on the above announcements, we can conclude that:
You can go to the U.S., but you can't stay in the above countries for 14 days before you go to the U.S. In other words: if you are a Chinese citizen (non-U.S. green card holder) and leave China, you need to stay in country 3 (other than the country listed in the regulations) for 14 days before going to the U.S.

The United States is not in Europe.
The United States does not belong to Europe, it belongs to North America. The main part of the United States is located in North America, bordered by the Atlantic Ocean to the east, the Pacific Ocean to the west, Canada to the north, Mexico and the Gulf of Mexico to the south, and the mainland is located in the temperate zone and subtropical region. The United States is the second largest country in the Americas, with an area of 9372610 square kilometers (including 10,000 square kilometers of land and about 200,000 square kilometers of inland waters).
U.S. Topography:
The topography of the United States is varied, especially in the West. The East Coast coastal area has a coastal plain, which is wider in the south and narrower in the north, and the coastal plain does not exist north of New Jersey, and there are also some glacial Sunschuchuan sedimentary plains in places such as Long Island.
Behind the coastal plain is an undulating foothill strip that stretches to the 1,830-meter-high Appalachian Mountains in North Carolina and New Hampshire.
To the west of the Appalachian Mountains is the interior plain of the Midwestern United States, which is relatively flat and is home to the Great Lakes and the Mississippi River and the Missouri River Basin, the fourth largest river basin in the world. West of the Mississippi River, the topography of the inner plains begins to rise and eventually enter the vast and sparsely topographically sparse Great Plains of the central United States. <>

First, in fact, it is mainly determined by geographical location, and secondly, due to security factors, these reasons determine that you need to take a detour when flying to the United States. The Earth is an ellipsoid, slightly flatter at the equator and flatter towards the poles. Then we can fly along high latitudes to shorten the flight distance with keys.
In addition, the Bering Strait polar climate belongs to the westerly wind belt, and we can save time and fuel by having a tailwind.
Second, we draw an arc of flight on the earth according to the flight path, and then directly connect China and the United States through the Pacific Ocean. By comparison, we can intuitively see that the route directly east through the Pacific Ocean is longer. International flights require flying over national airspace, which involves the issue of "freedom of air access".
In particular, each country has its own security no-fly zones. Therefore, in order to determine the route, fly over the airspace of a country, or repair, refuel or transit in a country, it must negotiate with that country and cannot fly without permission.
3. Even if there is a fixed route, the airline will report the route to the domestic countries the day before the flight departure to avoid accidents. As a result, civil aircraft cannot travel freely and fly freely. In order to ensure flight safety, the international air traffic control department also requires the devibrator to equip passenger aircraft flying across the ocean with a twin-engine system to cope with engine failures flying across the ocean.
At the same time, the climate over the Pacific Ocean is changing rapidly, making it easy to form ocean hurricanes, posing a huge risk to aircraft flights. Therefore, domestic flights do not choose to fly across the ocean, and most of them choose to fly along the land.
Therefore, after many considerations, the final route to the United States was decided, which is a suitable route both in terms of economy and safety performance.
The power of the ocean is unknown, but we all know that the power of the ocean is terrifying, which is why people should live in peace with the environment and not stand against it. >>>More

First of all, let's talk about the formation of foreign exchange reserves, foreign investors come to China to invest so they bring dollars, Chinese exporters export goods to get dollars, but the dollars cannot be circulated in China, so they sell their dollars to the central bank, in exchange for yuan into their own pockets, the central bank obtained these dollars are foreign exchange reserves. It can be seen from this that foreign exchange reserves are not real wealth, but more of a "value support" for foreign investors and Chinese exporters to provide a "value support" for the RMB in the pockets of foreign investors and Chinese exporters, which means that "with these US dollars, the RMB in your pockets is not waste paper, but supported by valuable US dollars", and the real wealth is the RMB in the pockets of foreign investors and Chinese exporters, and they have the final say on how to use it. Foreign reserves are all foreign currencies that cannot be circulated domestically, so they cannot be used to develop domestic industries, including the tertiary industry, and if you invest in foreign countries, the real economy is risky, and you can only invest in projects with little risk, such as U.S. Treasury bonds. >>>More
