Our school is nearby MACAO International airport,so I have opportunity to planes take off every day.Plane is really wonderful thing,thanks to it,people can travel to everyplace they want to go,this kind of transportation also make people's life longer and longer,which means save people more and more time.
But sometimes I was thinking that the plane is not fast enough,for example,if you want to travel from China to America,it will also take you about five to six hours by air,and the plane will also do damage to the environment.
So I am thinking of another kind of traveling style,it is also by air,but my idea maybe more funny.It is.........space-air plane/rocket!!I know it may sounds crazy,but this is just an idea.And,you can see that there is many advantages using this kind of tansportation,frist,it is environment friendly,but most part of is airline is in the space,so it will not leave too much CO2 in the atmostphere.Second,because in the space,there is not more air,so not more resistance,we can travel faster,save more time!
Well,it also diffcult to put it into practice,it requie people have an well-working body,it need plenty of time to prepare for one launch,and there is still not safety landing technology exit.so it need some years to be studied.America has begining this task.I believe it will come true someday.
