    During the weekend I travelled by air the first time
in my life. I generally travel by train and bus. It is
both cheaper and safe. But this was a short journey.
In the beginning I didn't feel very happily, but this
feeling did not last longer. The journey was very exciting.
I was soon high up in the sky among the cloud. The views
of mountains, fields and rivers were interested.
I enjoyed my short or comfortable journey very much.
This experience has shown that travelling in air is
actually the safest way of make journeys.
