Why do Santa Maria's streetlights shine a yellow light? Why do airplanes fly low and circle the Santa Maria Airport?

We've got Good Questions from our friends in Santa Maria tonight who want to know more about their city. Bebe Goldstad wants to know why do Santa Maria's streetlights shine a yellow light? Good Question.

The Director of Public Works says since 1960 the city has been using low pressure sodium vapor lights. They do cast a yellowish glow on everything. They were the most economical because they give off a high amount of light for a low amount of energy.

Santa Maria now has 65-hundred streetlights. It's modernized and now 15 percent of the them are newer, "induction light fixtures" which are more efficient and cast a white light. The next phase is moving to l-e-d white lights.

Robyn of Santa Maria asks why do I see airplanes flying low and circling at the Santa Maria Airport. I talked with airport officials and they say it's probably students taking flying lessons. When they practice take-offs and landings there's a lot of repetition and students just circle the airport between them.

I know you have a lot more questions so send them to goodquestion@ksby.com or better yet, friend me on facebook.com/JohnRegerKsbyNews. The only bad question is the one you don't ask.
