Earhart Vanishes: Lost Over the Pacific

Amelia Earhart s last confirmed radio transmission crackled with static and urgency. "We are on the line 157 337," she reported to the Coast Guard cutter Itasca, attempting to locate tiny Howland Island in the central Pacific. The Itasca received her voice clearly but could not establish two-way communication. After that transmission on the morning of July 2, 1937, Earhart and navigator Fred Noonan were never heard from again. Earhart and Noonan were attempting the longest and most dangerous leg of a planned equatorial circumnavigation of the globe. They had departed Lae, New Guinea, roughly 22 hours earlier in a twin-engine Lockheed Electra, aiming for Howland Island, a flat coral strip barely two miles long and half a mile wide. The flight covered 2,556 miles of open ocean with no landmarks and limited navigational aids. The Itasca had been stationed at Howland specifically to guide Earhart in by radio. But a cascade of technical failures undermined the plan. Earhart s radio direction finder may have been malfunctioning. The Itasca s crew was transmitting on frequencies she apparently could not receive. Overcast skies prevented celestial navigation during the final approach. The margin for error over featureless ocean was effectively zero. The U.S. Navy launched the most expensive search in its history to that point, deploying the aircraft carrier Lexington, the battleship Colorado, and dozens of other vessels to comb 250,000 square miles of ocean. They found nothing. The search was called off on July 18. Earhart had already secured her place in aviation history before the final flight. She was the first woman to fly solo across the Atlantic in 1932, five years after Lindbergh s crossing. Her disappearance generated conspiracy theories that persist nearly nine decades later, but the most likely explanation remains the simplest: the Electra ran out of fuel and went down in the Pacific.
