Goodwill Ambassa-Quiz #4 answer: 1942

Goodwill Ambassa-Quiz #4 asked,

What year was Lindbergh Field's current single runway (pictured) built?

And the correct answer is: 1942. As explained in the Wikipedia entry for San Diego International Airport:

"World War II brought significant change to the airfield when the U.S. Army Air Corps took it over in 1942 to support the war effort. The infrastructure of the airport was improved to handle the heavy bombers being manufactured in the region during the war. This transformation, including an 8,750-foot (2,670 m) runway, made the airport 'jet-ready' long before jet passenger planes came into widespread service." (The runway has since been extended to 9,401 feet in length.)
