Two Vought F4U Corsair fighters sit on the flight deck of USS Boxer (CV-21) on 19 May 1951, as documented by the period caption inked onto this photograph. In the distance, a Sikorsky HO3S plane-guard helicopter hovers over the water where a pilot had just gone down during flight operations -- a vivid reminder of the routine hazards faced by carrier aviators during the Korean War. Rescue helicopters like this one became a vital safety measure for carrier air operations in the early 1950s, often meaning the difference between life and death for downed pilots. Project: 218308
