Forty six years ago, on this day, January 22nd,1970
The Boeing 747, the world’s first “jumbo jet”, enters commercial service for launch customer Pan American Airways with its maiden voyage from John F. Kennedy International Airport to London Heathrow Airport.
The amount of carbon dioxide in the air was roughly 324ppm. As of 2026 it is 428ppm, but check here for daily measures.
The broader context was that by this time, humans have been flying since 1903 and in the post war era, commercial jet liners had become to be “a thing” thanks, in part, to Boeing using money they were given by the Department of Defence to create a cargo plane to prototype – aka the 707. There were also just a lot of surplus aeroplanes and pilots with the necessary skills. So commercial aviation in the 1950s is a good example of the Great Acceleration.
The specific context was that in the 1960s it was assumed that supersonic passenger travel would become a thing. Both JFK and Lyndon Johnson signed off on proposed jetliner funding for them, etc. But it turned out physics and economics had other opinions. There were also environmental issues around, for example, sonic boom and ozone depletion.
In the midst of this, the 747 was designed as a kind of stop gap. It would be big, not slow, but not fast, and would be rendered obsolete by the coming of not just, you know, Concorde, but the Boeing etc, equivalents.
What I think we can learn from this is that this is sometimes the standby technology that is supposed to be there for a little while. Sticks around because it is good enough. (Kind of a flying QWERTY keyboard – kind of.)
What happened next
And as we now know, for various reasons, that never happened. And the 747 stayed with us. It continued to be built with minor modifications, like those upturned wings. I think it’s still in use as cargo, but I’m not sure that anyone is still flying them for passengers because they’re heavy and out of date. Nope – there are still, as of Jan 2025, four airlines still using them! Which Airlines Still Fly The Boeing 747 On Its 55th Flight Anniversary?
I travelled on it a lot (never upstairs!) and it did the job. And in some ways, it was elegant. There’s all the airport films in the 70s. There’s this explosion, the bringing down of the Lockerbie plane, and of course, KAL-007
What do you think? Does this pass the ‘so what?’ threshold? Have I got facts wrong? Interpretation wrong? Please do comment on this post, unless you are a denialist, obvs.
