The Hughes H-4 Hercules - the largest flying boat ever built - made one 26-second flight in November 1947 and now stands preserved in McMinnville, Oregon.
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.
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.
