Another landscape, a rippled hillside with a sine-winding road wound across its surface. S-curve of a gradient approach... across the air, across time, across smell and polarized light, speeding through traffic signs posted here high up above the road. Aerial approach to the Frisch Flight Simulation Company building.     I usually flew from the start of the day. My specific assignment was the Army's Integrated Air Battle Mission Simulator, where several Pilots could fly at once over a common landscape the size of New Jersey.
