In July, Lockheed Martin completed the build of NASA’s X-59 test aircraft, which is designed to turn sonic booms into mere thumps, in the hope of making overland supersonic flight a possibility. Ground tests and a first test flight are planned for later in the year. NASA aims to have enough data to hand over to US regulators in 2027.

Aviation is one of the smallest contributions to greenhouse gas emissions as-is: in 2016 it was 1.9% of global emissions.

The danger the rich pose to the planet isn't being first in line for the second generation of supersonic transoceanic flights.

The danger the rich pose to the planet is them keeping coal and natural gas plants open longer because they personally profit from it. It's them keeping their taxes low, reducing our ability to fund renewable energy. It's them fighting tooth and nail against any new energy efficiency regulation (remember the incandescent lightbulb ban fight?) because it "hurts profits." It's them fighting against public transportation.

This? This isn't even in the top 50 of their ills against the climate. The hate for the rich is well placed. Applying that hate to basic science is dangerously misplaced. The rich love when people push-back on funding science efforts.

The problem is that those emissions cause more warming at that altitude. So fly just above treetops, please. https://oncarbon.app/articles/non-co2-effects-aviation you need to at least triple it

If you flew above treetops, you'd consume considerably more fuel because of air friction.

Yeah, forgot the interrobang. But really, air travel is a problem. It needs to be minimized. Not increased. Especially not increased in amount of greenhouse gas emissions per distance flown per person
