The Aviation Section of the Signal Corps, as U.S. military aviation was known, was totally unprepared to fight a modern war in April 1917. At the centennial of U.S. entry into WWI, this week's Ask an Expert Live with aeronautics curator Christopher Moore will explore the early history of American military aviation and its unpreparedness for participation in the Great War. Tune in on Facebook Live. 

Planning to attend in person? Meet at the pre-1920 aviation area of the Steven F. Udvar-Hazy Center. 

Every Wednesday at 12:30 p.m. we will go live on one of our Facebook pages with an Ask an Expert talk. We’ll select a different aviation or space topic each week, and a Museum staff member will discuss the history, stories, or personalities related to a specific artifact or exhibition in the Museum. Tune in on Facebook Live each week to join the talk and ask our experts questions.
