Human beings conquered the distance on earth by discovering wheels. They endeavored further. Then on December 17, 1903, the Wright brothers in America made the first experiment of flying in a plane. In the experiment, a machine carried a man and rose above by its own power. The machine was called 'aka airplane'. It flew naturally in a smooth speed, and finally landed without damage. That was human being's first real take-off. And now, they have got a supersonic speed. In a supersonic speed, something travels faster than sound! So the sky's the limit now!
Modern aircraft companies are making revolutions in aviation technology. Boeing as well as Airbus is producing modern passenger airplanes. These planes fly very fast. Boeing 787 flies 950 km/h. However, Airbus 350 is expected to fly at a speed of 945 km/h.
You find attractive ads on the websites of both Boeing and Airbus planes. Both have excellent features. But in speed, neither could beat the Concorde. It is the world's fastest supersonic passenger aircraft. Its normal speed was 2,170 km/h. The Concorde was a joint project by France and Britain. It started passenger flight in 1976. Unfortunately, the Concorde fleet was grounded forever in 2003 after a major accident.

Questions
Note : The speed of sound, which is approximately 760 miles per hour is called 1 Mach. An airplane flying less than 1 Mach or less than 760 miles per hour is travelling at subsonic speed. Faster than 1 Mach or 760 miles per hour would be a supersonic speed.
Sohan : Teacher, in the last class we read about modern aircraft. There were Boeing 787s, Airbus 350s, Concorde and so on. But which one is the best? Which one can we buy for our Biman Bangladesh Airlines?
Mr Ramis : A difficult question. There are certain things to consider. If you think of speed, Concorde flies the fastest. To many, it looks the most beautiful. But it's no more in operation.
Sohan : Between the other two aircraft?
Mr Ramis : Well, if you remember, Boeing 787 travels 950 km/h. So you see, it's not as fast as Concorde. But it's faster than Airbus 350.
Sohan : Yes, teacher. I remember Airbus 350 travels 945 km/h. It's 5 km shorter than Boeing 787.
Mr Ramis : Nice calculation! But there are other factors too. Say, passenger capacity, production cost and many more. Airbus 380 now is the largest and can carry more passengers than any other aircraft. Authorities have to consider so many...
Sohan : Yes, teacher. I understand.
