On November 2, 1947, Howard Hughes flew the world's largest airplane - the H-4 Hercules - one mile across Long Beach Harbor, vindicating years of ridicule and an $18 million gamble.
The Hughes H-4 Hercules flew just once in 1947, but its single minute over Long Beach Harbor silenced Senate critics and left an enduring mark on aviation engineering.
How Howard Hughes built a 320-foot wooden flying boat, silenced Congress with a single 26-second flight, and created the most ambitious aircraft ever constructed.
The Hughes H-4 Hercules holds the record for the largest wingspan of any aircraft ever flown at 320 feet, and has called Oregon's Evergreen Aviation Museum home since 2001.
