This week we bring you Part 8 of Alden McWilliams’ illustrated tribute to the pioneer fliers of the early days of aviation. He called it “They Had What it Takes” and this installment appeared in the September 1937 Flying Aces. It features aircraft developer Igor Sikorsky. Among Sikorsky’s many innovations was the first multi-motored plane.

Next week look for McWilliams’ feature on zeppelin ace Captain Ernst Lehmann, whose last command was the ill-fated Hindenburg.
