1.
Today's aircraft will be replaced with a new form of supersonic transport in a
few years' time.
2.
The new hypersonic aircraft that looks like a rocket will cover the distance
between Tokyo and Moscow in less than two hours.
3.
The future superliner of this class will have large windows that will allow
passengers to watch the panorama of the Earth.
4.
Airliner's routes will mainly lie in the stratosphere because the air resistance
in the lower atmosphere is too great.

alloys for new composite materials.
7.
Cryogenic fuels are used as both coolants and propellants.
