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 fifty miles per hour (80.5 km/hr). Baldwin landed at 6:05 back at his starting place.
