Myself Mike from the United States of America. When I was a kid I was thinking how an airplane flies in the sky. That was one kind of unbelievable thing for me.

But now I can understand the logic behind it. It is a great development in technology. We are making things for comfortable life. Where will be stand after 20-25 years?
