My Father is a driver Mechanic when he was in the Philippine Army, he used to fix his own vehicles because thats how it is there, the Government cannot afford to take all those trucks to a repair shop. He would spend so much time at their motor pool fixing those cars, he always comes home with him stainless steel tool box, smelling like a gasoline and his hands are dirty. I really admire him though because he works hard to be able to send us to school, he 's a good father to us, I miss him so much.
Anyway, I have a friend that lives in the State of Washington, her husband is working as an Engineer in one of the biggest Aircraft maker in the World. Her husband was in the Military before he quit and continue his study until he became an Engineer. A few months that company was using Alloy steel beams, as one of the parts needed for their airplanes. They also uses Titanium to make the aircraft very durable and lighter than most airplanes.
