I'd pay extra to take the train for shorter trips. The entire experience is better, from not passing through a security theater production to the larger seats. I've never had a train sitting on the tarmac for hours, either, my plane trips frequently involve waits and delays.

> had a train sitting on the tarmac for hours I took the Amtrak a couple times from DC through WVA and have had several delays trying to get from VA to KY due to priority being given to the freight trains. I remember one trip having a one or two hour delay in the middle of no where while we were side tracked. It is much, much more comfortable than a plane though.

I kinda knew I'd get called out on that, but, yeah, definitely more comfortable. You can even get up instead of, "everyone has to stay seated because any minute now we will be ready." Some trains have a food car. It's great.

. . . and the US airline industry has still not had a fatal crash in just under 25 years.

* 15 years Still impressive.

Public math. Ugh.

The problem was software that prioritized input from a fauly external sensor, over pilot control, and literally crashed planes directly into the ground. At a certain step in the sequence it was not physically possible for a pilot to pull hard enough on the control element to counteract the software. Could they have disabled the system? Only if they could figure out the specific software trying to crash the plane. Is…

Even more ridiculous, Boeing offered a second source of truth option, but marked it as an upcharge, which the airlines in question rejected. "No thanks, no need for a second AoA sensor, one is none is probably fine!"

Additionally, two feels like a really strange number. I would think three for a tiebreaker would be standard for any sensor with that much impact (no pun intended).

Concorde ? maybe? it literally changed the industry online to be cancelled later

The Concorde has been one of the safest airplanes in history, with only one accident in 30 years of service. The story is different for the Tupolev Tu-144, also known as Concordoski, a copy of the Anglo-French plane.

How was it a copy when it made a maiden flight before first Concorde?

Sigh... This myth that the only people who can competently manage developers are other developers has been floating round for decades. For some reason, developers seem remarkably blind to the skills other roles and disciplines require. Only a developer can do that, everyone else is basically useless fluff. Maybe it's a form of arrogance or just deep unself-awareness.

Let's apply your reasoning to medicine. I'm sure you would be completely fine with managers telling your surgeon what parts of the surgery can be 'optimized away'.

Haha, funny strawman. My reasoning is that non developers are capable of managing developers, notably people who have good management skills.

Your contention is that the surgeon should be running the hospital.

Hahah, indeed. So have you seen a law department in a company headed by someone who doesn't come from law background? How about a finance department headed by some schmuck who doesn't know anything about finance?

That's what happens if your employees don't care about your company.

I don't get it, is your point that the "deaths per 100M passenger miles" is underestimating the likelihood of death? Doesn't the metric already normalize for number of passengers on a plane?

It's obfuscating it behind enormous numbers. Most accidents happen on takeoff or landing, so per-flight statistics are ideal for them. Some accidents happen in flight, so I'd maybe include hours in flight somehow. But miles and people counts don't serve any purpose.

Does this matter for the average flyer? Sure, if you're in Hawaii and flying daily for island hopping purposes you should probably estimate your risk as being higher, but the average flyer is still going to have average risk per miles flown (by definition).

I disagree with you. You are stating it, but you are not giving reasons. Managers who weren’t developers tend to not be able to manage the team. They can’t help with or understand the technical decisions made. The non-technical managers tend to be project managers just focused on dates.

I sort of agree, and I do think it’s possible depending on the team. But unfortunately developers can be too opinionated and get focused on low priority things.
