Background: On the New Year's eve the world's first supersonic passenger liner TU-144 made its first flying test in the Soviet Union. On January 8th General Designer Andrei Tupolev, Chief Designer Alexei Tupolev and other makers of the new aircraft arrived at an airfield near Moscow to watch the plane's second test flight.
Four test pilots are climbing the ramp.
The takeoff ground run is not longer that that of the turbejet TU-104 plane.
The cruising speed of the TU-144 is 1,500 miles per hour which is three times higher than the speed of subsonic planes. The designers have done a good job to achieve this. They devised a new aerodynamic scheme, overall design and used new materials and techniques.
A feature of two TU-144 is that the nose part of the fuselage can go up and down.
Now it is going up. The operation takes more 10 seconds. The plane now locks like a sharp needle.
With the fuselage lowered the plane takes off and lands.
First interviews after the flight, first pictures.

The new aircraft is designed for 30,000 flying hours. It makes 10 years of troublefree service. The TU-144 will fly dozens of millions of miles at a speed twice faster than the velocity of sound.
