"Darn Sky Riders: Jet Trails Dim Sun, Palm Springs Gripes"
As you know our entire economy is dependent upon tourist trade, which is predicated on our bright sunshine and warm climate. Recently our sky has resembled a mob of exuberant sky riders performing an aerial circus. The ‘contrails’ are breaking down into a haze and creating a cloud-like appearance in the sky. The Air Force, so far, is flabbergasted.

Jets Increase Clouds. Reid A. Bryson said that jet aircraft contrails were one of the more recent types of cirrus clouds, which are comprised of ice crystals at high altitude. Where jets are operating today, cirrus clouds have increased by 5% to 10%, Bryson said. He estimated that if the day came when 300 supersonic transports were in the air at one time, the region of operation of most SST’s “might easily be 100% covered with cirrus clouds.” The net effect of this would be further to reduce the heating of the earth, and blue skies might become a rarity.

“Let’s face it, men” said a crisp talking, star-studded general, “you’ll either have to live with the vapor trails or move the City of Palm Springs.”
The resort area, it appears, is known as the “Palm Springs Intersection.” the freeway interchange of all West Coast aerial traffic.
So, the city officials and civic leaders, in an apparently unanimous, unspoken agreement, decided that a peaceful coexistence with the Air Force was the wisest course.
