Key words : withstand space base launch detach monitor hypersonic research melting point

A. Look at the picture and say what it is. Discuss with your partner.

B. Read the news report adapted from The Guardian.

The Falcon Hypersonic Technology Vehicle-2 (Falcon HTV-2) is the fastest plane ever built by human beings. It would fly from London to Sydney in less than an hour. Supersonic Concorde, by the way, could not fly at such a great speed. At the same time it would withstand temperatures of almost 2,000 degree C. This temperature is hotter than the melting point of steel.

The US Defense Agency will launch the Falcon HTV-2. First, they will set it on the back of a rocket. Then they will launch both into the space from an Air Force Base. The plan goes like this: engineers will launch the Falcon HTV-2 into the space on the back of a rocket; then they will detach the plane from the rocket; the plane Falcon will fly towards the Earth; engineers will guide and monitor it in its flight. The plane would fly at hypersonic speed of 13,000 mp/h. This speed is about 20 times the speed of sound.

The Falcon was born in 2003. It was born as part of a US military project. The project researched and built a special type of plane. The researchers wanted that the plane could reach any part of the world in less than an hour. They also wanted to use it for any purposes, military or civil. The plane was already tested in computer models.

The Falcon Hypersonic Technology Vehicle-2 would be mankind's dream aircraft in the days to come.

F. Have you ever dreamt of flying to a city/country of your choice? If yes, write about your dream. If not, try to imagine you are flying to that place in a plane. Write about your experience and expectations.

If you fly westward in a supersonic plane such as Concorde, you will land several hours before you took off. Can you explain how?
