Every Wednesday at 12:30 p.m. we will go live on the National Air and Space Museum Facebook page 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.
