Man, I’d love more trains but we can’t act like the infrastructure necessary to support them, if not present, is very challenging to develop. Even ignoring land acquisition (which is a big thing to ignore in populated areas where a train would most benefit the population), there are simple things like road crossings, other infrastructure crossing, etc. In this case an airplane may be simply a lower friction solution.
I don't disagree, and yet, despite all of that, new freeways can _always_ be built. And they require far more land and cost. It's totally possible for us to build things still. Just have to care.

> I am now on vacation That is the key here. People go all over the world for vacation. However vacations are not normal life (at least not for the vast majority of people), and can be ignored. In normal life people have a place they live, and they have people they visit. When looking for a place to live they consider the real trips they take (not cutting through corn fields), and that guides where they move to. Peop…
I have no idea what point you’re trying to make or how is my vacation “the key here”. I’m visiting a regular Czech town that just happens to be almost exactly 125 miles from another regular Czech town (the one where my parents live), and I used those two particular towns as an example of how 125 miles can be a pretty big deal in Europe (or really anywhere in the world that’s not the US).

Honestly, I'd feel better knowing it has a reserve system in case there's any issues, even if the batteries have more than enough power, beats having it and never using it, than needing it and suffering as a result.
The real benefit really seems to be that the electric motors have a much smaller failure rates than mechanical ones running near their top rpm. The hybrid motor can run at a much optimized RPM, so the idea is that this will improve the overall safety margin of the overall design. I could be wrong, but that's what the video said.

I'm pretty excited for the hybrid airplane. Use battery charge to get up to altitude. Hybrid power during cruise and top off the battery with the leftover power. Far less power requirements, far less fuel use, better climb performance, and can use the most efficient engine rather than hugely inefficient but power dense turbines. And as a bonus, put the prop power anywhere you want. Designs that distribute props acros…
> Designs that distribute props across the leading endge, or right on the leading edge of the rudder, are exciting From a purely aesthetic point of view, pusher props are way cooler. If the wings are far back and the plane has canards, even cooler.

USA's lacking rail commutes come down to the fact that America's leaders made the deliberate decision to destroy its own rail network and force people onto planes. The electric range of this aircraft is 125 miles[0], which is at the low end of the range where conventional intercity rail is time-competitive with the plane. A bullet train would absolutely smoke this. tl;dr I have a few qualms with this app[1]. Now, thi…
> USA's lacking rail commutes come down to the fact that America's leaders made the deliberate decision to destroy its own rail network and force people onto planes This is utterly 100% false! The US made the decision to focus rail roads on freight. You never think about freight because you never use it for anything personal, but it is still there. The US beats any place in Europe for Freight and few countries even c…
1. Freight customers spend longer waiting for their deliveries, and pay more money for them. As a result, a lot of mid-size freight customers have moved to trucking instead, and the market has shrunk.
2. To save money as less-valuable cargo is pruned from their networks, freight railroads have been downgrading their infrastructure from double- to single-track with sidings. This would be acceptable, except...
3. Freight trains have gotten longer and longer in order to reduce the crew needed to attend to a given amount of freight. Sidings on single-track routes are rarely long enough to accommodate mainline freight trains, so passenger rail gets delayed, and grade crossings stay closed for way longer.
That last bit is actually why I personally complain about freight railroads. I am someone who has spent a good chunk of his 2026 lobbying Utah's state representatives to adopt the Rio Grande Plan[0]. You see, Salt Lake City is divided in thirds by UP freight mainlines, which get hourly freight through-traffic that paralyzes car and pedestrian traffic across the various sides of the city. The railroads themselves don't inconvenience passenger train traffic[1], but they absolutely make it miserable to walk, bike, or drive across the city, and we can't run any transit services parallel to the railroad for obvious reasons. Everything that has to cross the tracks reliably has to go over one of two rail-crossing bridges in the entirety of downtown.
The reason why you are saying "a bus would be better" is primarily a matter of federal infrastructure spending. Buses get to ride on the Interstate Highway System for cheap, and government-provided highway infrastructure is significantly better for both freight and passenger traffic than the privately run railroads can offer. But at the same time, buses are a demonstrably worse answer to the question of "how do we get a bunch of people from one city to another" than trains or planes.
Personally, if money was no object, I'd call for the government to run intercity rail corridors along highway rights of way with open interconnection, overhead catenary, passing tracks, and passenger-priority dispatching. These would specifically be open to both passenger and freight rail, specifically because both are suffering under the weight of hedge funds that moonlight as Class I freight railways.
[0] The Rio Grande Plan is a citizen-led initiative that calls for building a train box in downtown Salt Lake City along 500 West and burying all heavy rail freight and passenger traffic inside of it.
[1] ...because we built our own railroad parallel to the UP mainline. Amtrak's California Zephyr service is absolutely inconvenienced by Union Pacific, though - in fact, it's the worst delayed route in the entire network!

Yes, it doesn't even make sense to make electric trucks, let alone airplanes. Or they'd be mostly battery.
There are a lot of trucks that never go very far in a day. Many of them are used for "last mile" delivery. They start at a warehouse, get loaded, then go make a few deliveries and head back for the next load. While fast charging is needed, they don't go very far and thus don't need extreme range. It is a valid question though: how do we get more of the long distant freight onto trains. Followed closely by how to we g…

Hybrid after the first 125 miles, total range 500 miles. Their problem is diversions - an incident at the destination airport may mean an passenger aircraft may need to land at an airport which could be a couple hundred miles away. The hybrid powerplant throws the fuel efficiency numbers off so goal is not to run it unless needed, but they could not get certification without it.
Unless they have a whole new airport and flying experience, I don’t think a lot of people are going to fly just 125 miles. That’s less than two hours of driving. It would be 2 hours of just airport shenanigans much less the flight itself.
