Today we’re celebrating the 117th Anniversary of Flight! On December 17, 1903, two brothers from Dayton, Ohio did what most thought impossible. After years of scientific testing and determination, Wilbur and Orville Wright each flew their handmade flyer for the first time, demonstrating powered, controlled flight. Honor their historic achievement and check out the Wright Brothers National Memorial in North Carolina. #WrightBrothersDay! As the Flyer rose for the first time, John Daniels would capture one of the most significant photos of the 20th century.

No, the bison at Yellowstone National Park in Wyoming haven’t learned to fly. Yet. Despite weighing as much as 2,000 pounds, bison are strong swimmers and can run up to 35 miles per hour. They can jump over objects 5 feet high and have excellent hearing, vision and sense of smell. Photographer Alex Walczak witnessed their power when he took this wonderful picture, “There was a whole group of them rolling around and I noticed a young bison running all over the place on the hill. I got this photo while it was in the middle of jumping and kicking like a bronco. After about 5 minutes of racing around, this young bison calmed down.” We guess it just needed to burn off some energy. Photo courtesy of Alex Walczak
