The San Diego Union-Tribune on Sunday released never-before-published shots of Lindbergh from April 28, 1927.

Harry Bishop, chief photographer for what was then the Union and Evening Tribune, shot the 25-year-old as he climbed for the first time into the cockpit of the Spirit of St. Louis, the plane custom-built in San Diego by Ryan Airlines.

The newspaper published a few photos from the test flight. The rest were archived for nearly a century.

Three weeks after they were taken, Lindbergh and his aircraft made history by flying from New York to Paris, 3,610 miles in 33 hours.
