No idea what happened to them. I'd love to see them again, although I'd probably cringe about how dated they are.
Today there are documentaries celebrating the PM and engineers of 747. None for the cancelled project.
Quite a few sources say that the reason Nixon approved the Space Shuttle was to appease voters who had been negatively impacted by the cancellation of the Boeing SST project.
Is that what that boom.aero post was about? Sorry, I wasn't able to read into it.
Either way, when these things come up, I am always curious what happened to the realization that air travel is a multitude worse than any other type of air pollution because it essentially directly delivers harmful particles right into the highest strata of our atmosphere. Is that no longer a concern with the jet-setting, globe trotting liberals? Or is it too inconvenient to their lifestyle and therefore will simply be ignored? Or maybe scientists were totally wrong about fundamental research?

"The IPCC has estimated that aviation is responsible for around 3.5% of anthropogenic climate change, a figure which includes both CO2 and non-CO2 induced effects. The IPCC has produced scenarios estimating what this figure could be in 2050. The central case estimate is that aviation’s contribution could grow to 5% of the total contribution by 2050 if action is not taken to tackle these emissions, though the highest scenario is 15%."
So, it's a concern, but far from the largest. There have been pretty significant advances in fuel efficiency, lighter aircraft, stuffing more people into a single plane, etc.
