January 2024 in Review

Most frightening and/or depressing story: 2023 was “a year of war“, and so far 2024 is not looking better. Those diplomatic grand bargains you always hear about seem to be getting less grand. And the drumbeat for a U.S. attack on Iran got louder.

Most hopeful story: According to Bill Gates, some bright spots in the world today include gains in administering vaccines to children around the world, a shift toward greater public acceptance of nuclear power, and maybe getting a bit closer to the dream of fusion power. He pontificates about AI, and my personal sense is it is still too soon, but AI does hold some promise for speeding up scientific progress.

Most interesting story, that was not particularly frightening or hopeful, or perhaps was a mixture of both: The return of super-sonic commercial flight is inching closer.

what’s new with super-sonic flight

NASA and Lockheed Martin claim to have a prototype supersonic jet whose sonic boom sounds “like a car door slamming heard from inside”. This could open the door to commercial supersonic flight over populated areas. Well, we don’t even have commercial super-sonic flight over the oceans at the moment, which would be helpful to long-haul travelers. The article doesn’t say when this might happen, but it doesn’t sounds soon. The article does mention that there is at least one other company working on a supersonic passenger jet which “it hopes” could be “in the air” (for testing presumably?) “later this year”.

what’s going on with supersonic travel

Wired has an article on the status of new supersonic travel projects.

Boom Technology, based in Denver, Colorado, is building a jet that could fly around 50 people at Mach 2.2, or 1,452 mph, more than twice the speed of sound. Nevada’s Aerion Corporation is making a pointy-nosed business jet, good for Mach 1.5. Both want to make their first deliveries by 2023.

NASA and Lockheed Martin are working on a Low Boom Flight Demonstrator to show that the thundering sound that shadowed the Concorde—and prevented flights over land—can be minimized. That plane may one day get an X designation, labeling it as the latest in a long line of experimental aircraft. It’s a fitting callback to the very first X plane.
