Comment on ” The Tool”

This article gave me a great feeling of those people who invented airplane. Aircraft for society now is just an ordinary transportation for people to traveling from a place to place. This article made me comprehend the difficulty of making the aircraft，from the beginning of invention until the moment of seeing it flight into sky. Many difficult problems were out during processed the aircraft, as compared the past and modern technology there were a big difference. So it was difficult to invented a aircraft during that period. They have to deal with thermodynamics, and the swarm of preoccupied draughtsmen tackle their work. But in the end they still invented. I admire their perseverance and teamwork，the moment the airplane took off makes me the great sense of accomplishment. I learned a lot from this article. As long as there is determination to do something it will succeed.
