According to http://hawaii.gov/hawaiiaviation/publications/hnl-gateway-brochure/AirportBro-web-part2.pdf
Overseas and International TerminalsThat seems to mean the photos ARE from 1961, not the early seventies. And I guess David is right about the boy being the older brother, or Calpernia is right that the photo is a photoshop. Geesh.
(John Rodgers Terminal)
The John Rodgers Terminal was dedicated on August 22, 1962. The Diamond Head Gull Wing was added in 1970 to handle B747 aircraft. The airport’s three-level International Arrivals Terminal was completed in 1973.
Why? It's just completely out of the question that the airport could look the same 10 years later? You think Hawaii renovated their airport every 5 years?
