I have a copy of Life magazine that I found in a shop selling such things in a back street in Stockholm, and it contains an advertisement for the debut of the 747. The most noticeable thing about the magazine though is the number of cigarette adverts. Times change.
I flew it many times, and it was great to use the upper deck, which in the early days had only about a dozen seats. A unique experience. And one time my wife and I flew back from London on one, using THAI. I'd used mileage to get free economy tickets but, despite that, we were upgraded. Being upgraded on free tickets is cool.
