On January 18, 1911 Eugene Ely became the first pilot to successfully land an airplane on a warship.
The first photo, taken by Tribune photographer Edward “Doc” Rogers from above biplane, shows Ely being readied for flight by sailors aboard the USS Pennsylvania, anchored in the San Francisco Bay.
The second photo, taken by San Francisco photographer Weigner, shows Ely seated in the plane, ready to fly. The photographer kneeling on the right is Doc.
