We take so much for granted now

I was reading the other day about 1500 giant concrete arrows strewn across America to guide mail planes pre radio/radar/IFR/GPS. They were spaced every 3-5 miles apart, painted bright yellow, measured 50-70 feet across. They also had rotating beacons mounted on 50 foot pylons. Pilots would basically follow the arrows to their destination
