NACA's 9th Annual Aircraft Engineering Research Conference held in May 1934. Quite a gathering of the most notable people in aviation at the time. In Langley's early years of crafting flight, aviation pioneers flocked to the center for engineering conferences. This photo was taken in Langley's Full Scale Tunnel during the 1934 Aircraft Engineering Research Conference, with Orville Wright, Charles Lindbergh, Jimmy Doolittle and Howard Hughes and many others in attendance.
