In 1910 Baldwin designed his own airplane, and it was built by
Glenn Hammond Curtiss. It used a , four-cylinder Curtiss engine that was later replaced by a Curtiss V-8 engine. On September 10, 1910, Baldwin made history with the first airplane flight over the Mississippi River. The St. Louis flight started just east of
Bellefontaine Cemetery. Baldwin and his Red Devil plane took off at 5:11 p.m. 200,000 citizens lined the riverfront on both sides to watch the red biplane fly from the north St. Louis field and land in Illinois across the river from Arsenal Street. On the return flight, the aviator astounded the crowds by flying under both the Eads and McKinley bridges at . Baldwin landed at 6:05 back at his starting place. Baldwin flew it at an air meet in
Kansas City, Missouri, on October 7, 1910. He spoke to State
University of Iowa engineering students on October 11, 1910 and flew demonstrations at the
Iowa City, Iowa fairgrounds on October 12–13, 1910. The flight on October 12 was unsuccessful. On October 13, he flew two flights, one of which was photographed by Julius Robert Hecker. On the second flight he did not gain sufficient altitude and the plane was damaged on a barn but he was uninjured. He then took his airplane to
Belmont, New York. He put together a company of aerial performers including
J.C. "Bud" Mars and Tod Shriver in December 1910 and toured countries in Asia, making the first airplane flights in many of those locations. The troupe returned to the United States in the spring of 1911. ==Red Devil==
