First airplane landing on a warship, 18 January 1911
Eugene B. Ely's Curtiss pusher biplane at rest on board USS Pennsylvania (Armored Cruiser # 4), immediately after it landed during the morning of 18 January 1911. The ship was then anchored in San Francisco Bay, California. Ely (with rubber inner tubes around his shoulders, and wearing a leather helmet) has dismounted from the plane and is talking with a man standing in front of the plane. Note the sand bags attached to lines behind the plane, used to stop it after it reached the deck. U.S. Naval History and Heritage Command Photograph.
