NowQantas plans to complete the voyage in a direct flight and take passengers to the other side of the world in 20 hours.

This voyage will refresh Singapore Airlines’ nearly 19-hour direct flight record (Singapore’s direct flight to New York), making it the longest direct flight in the world.

Of course, the premise is that Qantas decided to launch after the test.

This 20-hour direct flight not only requires technical improvements in the aircraft itself, but also considers whether the body of the aircraft can be eaten or not. Finally, it must be guaranteed that it is a profitable business.

New York’s voyage is slightly shorter than the 20.5-hour voyage of London to Sydney, but it also takes 19.5 hours to fly. At that time, the aircraft will not only carry dozens of employees “passengers”, but also scientists and medical researchers to detect and observe the human body’s response to this long-distance travel.

We know from the basic understanding of the circadian rhythm that the more time difference between departure and arrival, and the flight to the east will make the jet lag more serious.

Stephen Simpson say, he is Charles Perkins of the University of Sydney The person in charge of the center. This institution is also a partner for Qantas to study the jet lag.

Last year, the research on the cooperation between the two has brought about some changes.
