Flying, in-general, is inefficient unless it's a large, lifting body in ground effect.
Flying on a full or almost-full plane is more carbon efficient than driving solo. And that's not taking into account the cost of the road networks we build and maintain to allow high volumes of vehicular traffic. https://yaleclimateconnections.org/2015/09/evolving-climate-...

How loud was it and how often did you experience it?
They did it near London once by in error. One little Typhoon can produce an unbelievably powerful sonic boom. I felt it as a loud crack/thump on my roof. Now, imagine a Concorde going supersonic...

Unless we dramatically increase vacation time or dramatically increase rail speeds, that would mean that many people would not be able to see their families and friends or travel to events.
Absolutely not. 300 kph HSR rail exists in developed countries. (2680 miles) / (300 kilometers per hour) = 14.3768064 hours That's coast to coast in ~ 1/2 day. Ships and blimps represent a much larger decrease in travel time over airplanes than rail. They perhaps pose a to be solved, but rail doesn't.
I’d still consider a say 48h trip from SoCal to NYC provided I could work over wifi, but otherwise it’s really a nonstarter.

It would be nice if we had publically funded communication etc tools. I am not seeing a valid business nodel here that does not involve either massive spying, or poor people loosing access to rest of society.
How does having public funding for communication help? Having a zoom equipped laptop available for use in a county building isn’t much of a stretch. Public funding of communication will also guarantee spying.

Air travel is not a problem because the emissions per kilometer are that bad but because one can easily travel one or two orders of magnitude farther than one usually would.
So your preferred solution is to restrict the allowed travel radius of people, a bit like with medieval serfs?
They will still use an enormous amount of fuel, carry fewer passengers, and heavily pollute the environment. I'm not too excited about the prospects.
Wait until you hear about SpaceX.

What a rhetoric device. Is your preferred solution to let people die in droves to a mass extinction ?

Air travel has a big PR problem, because somehow a lot of people think it's the absolute worst for the environment. While on many routes a car is worse in terms of CO2 emission per trip than a small to mid sized airliner if there are less than 3 people in the car. Similar for your suggestion that we should take ships over the ocean, because cruise ships are much more polluting per passenger mile than modern airliners…
> While on many routes a car is worse in terms of CO2 emission per trip than a small to mid sized airliner if there are less than 3 people in the car. Wow. I read that one plane trip can increase your carbon footprint by a greater magnitude than all your typical actions to reduce it. Does anyone know where to find some data?

Nobody in this thread has suggested that.
