I love design especially for the military, our military. I have never enjoyed myself more than designing a situational awareness computer for the A-10 Warthog. The military gave us the available dimensions and what computers they were going to use, the PC104 and PC104+ specs, 1 stack of 4 boards and i stack of 3. I suspected the military was going to change that to 4 and 4, so that's the way I designed it ... and they did. No problem. The five prototypes we made were never suppose to fly. I figured the military once they saw them and fitted them in, they'd change their mind. They did. I designed them for 10 gs in all directions. They military flew them and they handled perfectly. My company then got an order for 100 more and the project was given to a junior engineer.
