Charles A. Lindbergh (crouching at center) prepares for a flight in an experimental glider in Lebec in early 1930. The wings are being put on the glider after it has been lifted off of owner W. Hawley Bowlus' trailer.
Lindbergh is doing the same thing here that he's doing in this photo. The Popular Science Monthly photo essay says he is "hard at work soldering a wire in assembling the engineless sailplane which he flew."
The famous aviator Col. Charles A. Lindbergh conducted "gliding experiments" in Lebec the first week of February 1930 with W. Hawley Bowlus, who was considered America's foremost gliding pilot according to Popular Science Monthly, which did a 3-page photo spread in its May 1930 edition as seen here.
Together they established a mountain camp to learn the "new sport of motorless flying."
These were halcyon times for the most famous man in the world — three years after his triumphant solo flight across the Atlantic in the Spirit of St. Louis, and two years before the kidnapping and murder of his 20-month-old son, Charles Jr., by Bruno Richard Hauptmann.
In the aftermath of the kidnapping, it's said Lindbergh would sometimes hide from the paparazzi at the Newhall home of a friend, William S. Hart.
