If everything goes as planned by this company, in a few decades we will be able to make trips to 6,200 km / h that will reduce transoceanic flights to three hours
This would be the supersonic aircraft developed by Boeing.
Today, supersonic commercial aircraft are one of the major research directions of airlines in the world. This aircraft will significantly reduce the time required for flights. According to preliminary estimates, supersonic aircraft may begin flying in the mid-2020s . Similarly, investigations are being conducted in the field of commercial flights at hypersonic speeds, but they are more theoretical than practical.

According to Aviation Week, the at the speed of the new plane will be 6,200 km / h and the flying height will be 28,900 meters. Thanks to these characteristics, the plane, if it is built, will be able to make transatlantic flights in two hours and transoceanic flights in three.
Variable cycle reaction engines will likely be used, similar to those used for SR-71 Blackbird reconnaissance aircraft, as a propulsion system in the aircraft. With the help of these power plants, Blackbird set a record speed for a straight line flight: 3,529.56 kilometers per hour. The advanced engines of a hypersonic passenger aircraft can operate reliably at a flight speed of about 5 Mach.
In July 2017, the US company Lockheed Martin's Skunk Works research division conducted the first flight tests of the prototype SR-72 hypersonic unmanned aerial vehicle. The SR-72 project was first introduced by Lockheed Martin in 2013.
The first prototype flight was held at the US Air Force airfield. in Palmdale, California. There is the headquarters of the Skunk Works division. During the first flight, the drone was accompanied by two T-38 Talon training aircraft. The details about the first tests were not revealed, but, probably, they were successful.
