Howard Hughes' private airport, also known as the Spruce Goose Hangar or Playa Vista Airport, is located in Los Angeles, California. Built by Howard Hughes during World War II, it housed the H-4 Hercules, also known as the 'Spruce Goose,' an experimental aircraft with the largest wingspan of any aircraft ever flown. The hangar, now known as the Hercules Campus, has been transformed into a mixed-use development with office space, retail outlets, and sound stages, serving as a hub for creative businesses and technology companies while preserving its historical and architectural significance.
