I assumed the history of noise externalities from supersonic aircraft might merit a broader discussion of externalities.
It’s great that they are talking about air pollution, but I’d still argue that there are many other externalities to supersonic air travel, (and sub sonic air travel, and ground transport, etc)
I just think we’d get saner transport policy and better innovation if we talked about them, and how to balance the benefits for people inside the vehicle for the costs to those outside the vehicle.
But there's a huge market in conventional tourists that have more flexibility and could choose from more options.
A typical tourist-class trip is going to be one day of "Travel Misery Time" followed by "Actual Vacation" followed by another full day of "Travel Misery Time".
Yeah, theoretically it might be less than a full day door-to-door, but if you're not an experienced traveler with expert experience in managing timing, baggage rules, TSA procedures du jour, and navigating the facilities, you're probably writing off the whole day of arrival and departure. Nibbling away a couple hours in the metal death cylinder doesn't solve that.
What if we said "we can swap one day of Travel Misery Time for two days of Resort on Wheels Time?" You might get fewer days at the destination, but an overall more enjoyable trip. Rail can offer that. Even today's Amtrak long-hauls offer a comfortable sleeper room, real food, and actual scenery, and no airport suffering, and there's no reason future offerings couldn't introduce other amenities (i. e. a spa car, or scheduled entertainment).
I can absolutely see tech salespeople using this mode of travel for critical meetings. Fly out at 0600 ET from JFK, arrive into LHR at 0900 ET/1400 GMT for a 1500 GMT meeting, do dinner and such, then fly out at 0900 GMT the next day to arrive at 1200 GMT/0700 ET for a full business day. Minimal jet lag.
What you're describing is high-end private air travel (for the rich and not time sensitive) and cruises (for people looking for a vacation in a box).
He once told me of a story when some exotic piece of equipment broke, and there was NO replacement on in Europe. After a mad scrable, they did find something and they had to fly in that special camera rig thing on a private jet.
This means these VIPs might not be able to land where they want.
Another issue is that these planes fly higher and take longer to reach travel speed, which eats into the the travel time benefits for shorter flights.
Yes, tools like zoom alleviate the problem somehow but not completely.
Sure trans-Pacific and trans-Atlantic travel are big routes but there’s also a huge amount of traffic that goes Europe, Asia, Australia / New Zealand
(I love high-speed rail; I enjoy it in Europe. I think Brightline's implementation may need some work before it's scaled up.)
Holy Shit. That's beyond just terrible.
If anything, being able to just fly over the ugly parts and arrive directly at your plastic wrapped all inclusive resort is a good way to increase the social divide and drive us closer to a war.
See: the US' painful and bizarre attempts at butchering its relationship with Canada. The integration of the two economies means that such ham fisted manoeuvres take money out of people's pockets pretty fast.
In a pre-mass travel world, I can see someone like a certain leader attempting to annex Canada. Now? It's unthinkable. Just saying it causes billions in damage.
Didn't stop them from getting into a war
Hardly fait to blame regulation here, the problem was that it was incredibly loud and unpleasant. You can try to make it sound like government overreach, but it takes some serious mental aerobatics.
There should be a name for the principle that one needn't look for more complicated explanations when economic ones suffice.
If anything it's a miracle how practical the Concorde was and how long it remained in operation
Fuck the rich, take normal airliner like everybody else if you are so poor to not have your own jet. We are not bending health standards to whims of few moderately wealthy individuals, sounds like some societal progress there.
A sort of self-regulating issue for a change.
And the overflight bans were a large part of the reason for all the sales to fall though. If the development/maintenance costs had been split over hundreds of craft as planned, they would have been much cheaper to both buy and maintain.
There is still the issue of high fuel costs, but fun fact, most of the cancellations came in months before the 1973 oil crisis.
Today, we see similar evidence in that Boom is being forced to develop their own engine because none of the actual engine makers want to make an engine suitable for a SST. I believe there is considerable skepticism that Boom will be able to do this, btw.
It should be noted that even subsonic airliners have gotten a bit slower over time. Fuel economy > travel time for them to some extent, even being subsonic.
At extremely increased cost. It's a hard sell in an industry that's competing for price efficiency.
If we could go from SF to Tokyo in 2 hours, it would permanently change geopolitics. Imagine commuting between Shenzhen and SF. One foot in each of the two most innovative cities on Earth.
The smaller our world becomes, the more peaceful it becomes.
and the quicker disease can spread.
> and the quicker disease can spread.
HN has attracted its share of luddites. People who aren't interested in building a better future. But are very interested in tearing it down.
When did HN become a place where dreams of a better future were met with proclamations of disease?
As there as been a general broadening of discussion as to exactly what "a better future" means and I suppose more specifically to whom.
What causes an increase in adverse outcomes, at least for fast-moving pandemics such as respiratory pandemics, is spread between risk tiers. For example, in the case of a pathogen with a significant age-dependent morbidity/mortality rate, one of the most dire threats is spread within multigenerational households.
Providing resources, opportunities, and guidance to facilitate spread within the low-risk tier while briefly isolating that cohort from the high-risk tier is likely to produce better outcomes.
Stated more tersely: the human proclivity to travel and share immune information with peers is a strength, not a weakness.
hmm, ok, since your profile says you study epidemiology sometimes I guess that's a totally reasonable take I hadn't considered. I was of course going off the stuff that was going around during Covid's height when people would refer to theories that faster and increased international travel would lead to more pandemics, and that Covid worked as predicted by that theory.
Is there strong evidence that's true?
A supersonic bizjet is a possibility. It's not cost effective, but it's a status symbol.

But it did not explode, it crashed. The cause of the accident was FOD (Foreign Object Damage). Debris on the runway, a 17"x1" strip of titanium, caused damage to the tire which caused additional damage and ultimately the crash.
Perhaps less dramatically, but that's not a unique-to-Concorde kind of accident. FOD is taken seriously in the aviation industry.
