Edward N. Hines, decades earlier, came up with the idea of the line down the middle of the road to keep passing cars from hitting each other, day or night.
I grew up on the edge of Hines Park (now in the middle of Rashida Tlaib’s district). It sickens me to think what’s happenee to the area that was *correctly* called the Arsenal of Democracy in the 40s. That term morphed over time, but that was the original usage.
Henry Ford built Hydra-matic and the Willow Run Airport next to it in 1941 to build B-24s. The plant floor had a natural 2% grade and B-24s rolled slowly under their own weight from one end of the plant to the other. They rolled out of the plant door onto the tarmac of Willow Run, were fueled up, and took off for service.
At peak operation through much of the war a new B-24 took once an hour, 24/7.
After the war GM took the plant over to manufacture power trains, and until the mid-90s it was the largest plant operating under one roof in the world.
That's incredible.
One way or the other, Germany was doomed.
