On June 2, 1943, Ensign Kinnick was on a routine training flight from the aircraft carrier , which was off the coast of Venezuela in the Gulf of Paria. Kinnick had been flying for over an hour when his Grumman F4F Wildcat developed an oil leak so serious that he could neither reach land nor the "Lexington", whose flight deck was in any case crowded with planes preparing for launch. Kinnick followed standard military procedure and executed an emergency landing in the water, but died in the process. Rescue boats arrived on the scene a mere eight minutes later, but they found only an oil slick. His body was never recovered. Nile Kinnick was the first Heisman Trophy winner to die; he was a month and seven days away from his 25th birthday.
