While I was organizing my magazine collection (see previous blog), I ran across a 1937 issue of California Highway Patrolman magazine. It had an interesting story about how the CHP, the California Air National Guard and a CBS radio affiliaqte in Los Angeles teamed up to monitor Southern California traffic. Each Sunday, a CANG pilot would take to the skies over LA in a bi-plane. If the pilot spotted a traffic back up below, he would use a two-way radio to contact the radio station. The radio announcer would then broadcast the delay over the air. I wonder how well this worked back then. If I'm not mistaken, most cars on the highway in 1937 did not have a radio.
Has anyone ever heard of another early effort to monitor highway traffic from the skies?
