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?
Something like that. The way I read the HNL history says that they renovated or replaced the international terminal in 1962. But I’m really wondering about the 1961 date on that particular empty terminal photo. Why is it empty? If anything that looks like a late-sixties, early-seventies style terminal as does the Dad’s clothing, the wide band watches and such.
