Read the following essay and answer the questions.
Most commercial airplanes travel at about 500 to 600 miles per hour.
SR-71 Blackbird, which was developed by Lockheed Martin in the 1960s, could fly as fast as
2500 miles per hour. At that speed, you could go from Tokyo to New York in just around
three hours. So why does it still take so long for ordinary people to fly?
I
The
to shatter windows
One of the biggest problems is that when a plane flies faster than the speed of sound it
breaks the sound barrier, causing a sonic boom. This boom is
thousands of feet below the plane. II Unfortunately, a lack of fuel efficiency and the
high costs of maintenance made it unprofitable. It retired in 2003, just a few years after a
major accident.
But the dream of supersonic travel never died, and engineers at NASA have finally
figured out a way to reduce the sound of a sonic boom to little more than that of a car door
shutting. III If all goes well, they will use the data they collect to try to convince
regulators to update aviation laws to allow commercial supersonic flight. At least three
companies in the US are hoping to advantage of such a change, and they aim to put
supersonic planes in the air within the next decade.
