Fourth Annual Engineering Research Conference
EVERY SPRING for the past four years representatives of the aeronautic industry have visited Langley Field, Va., to see and hear of the work being done by the National Advisory Committee for Aeronautics. Each year an increasing number have made the trip and on this year’s visit, which took place May 14, the N.A.C.A. was host to more than 200, almost twice as many representatives of commercial airplane manufacturers, accessory manufacturers, bankers and reporters than attended last year.
