(Sweetwater County, Wyo. - March 16, 2024) The Sweetwater County Historical Museum was recently made aware of a letter and a photograph that provide a glimpse of long-distance air travel from Sweetwater County in the 1920s.
On September 21, 1927, Mary Berta of Rock Springs wrote a letter to H.M. Berry, Boeing’s Rock Springs manager, regarding her recent flight from Rock Springs to Chicago aboard a Boeing 40, a mail-carrying biplane with passenger accommodations for two.
The Model 40 was Boeing’s first passenger aircraft and made its formal introduction on July 1, 1927. It was a large transport for its time, with a wingspan of 44 feet, 2 inches, an overall length of a little over 33 feet, and a gross weight of 6,000 pounds. It carried a pilot in an open cockpit, two passengers in tiny individual cabins, one in front of the other, and up to half a ton of cargo.
In her letter, Mary described “The outstanding courtesy of trained attaches, the surprising comforts provided for the passengers, the gorgeous scenic delights beneath, the ever-spreading panoramic views and the trembling lights of the many cities we passed over a night, are all never-to-be neglected memory.” She also went on to say: “I was impressed with the wonderful safety devices arranged for illuminating the night landings and the beacon flash lights along the course to direct the pilot.”
The Bertas were a civically active Rock Springs family. Mary and her brother Tom Berta, owned and operated several show houses and theaters in Rock Springs in the 1920s, including the Lyric, Oracle, Grand, and Rialto. Another brother, Joseph Berta, served as Chief of the Rock Springs Police Department and is credited with being instrumental in creating the town of South Superior and serving as one of its mayors. Dominick Berta, yet another brother, served as a deputy sheriff under Sheriff Al Morton and as Rock Springs Chief of Police under Mayor Chris Bunning. Mary died in 1967, age 83.
