XA jet races by overhead; shortly
thereafter, there is a loud bang. The
plane has broken the sound barrier.
At speeds of over 1,200 kilometres
per hour, sound waves ahead of the
aircraft are compressed and spread
out behind it in a conical shape.
Whomever the cone passes over
hears the sonic boom.TEven faster than flying! On a test
run, the Japanese maglev became the
world’s fastest-ever train by reaching
an astonishing 603 kilometres per
hour. A maglev link between Tokyo
and the city of Nagoya is set to open
in 2027. A section of the journey
covering 350 kilometres will take
about 40 minutes. That’s 20 minutes
quicker than by plane!122 september 2019
