NASA is ready to conduct the first tests of a supersonic passenger aircraft by 2021.

According to representatives of the US National Aerospace Agency, the development of a passenger supersonic airliner, which began in 2016, has already entered its active phase, and, given the current developments, experts believe that a unique aircraft can make its first flight by 2021, and in If the tests of the aircraft are successful, then by 2025 these aircraft can begin to actively operate.

On the other hand, independent experts do not see any uniqueness in the creation of this aircraft, since the aircraft will have a small capacity, and at the same time will have a high cost.
