        Not even indestructible, just big heavy destructible death traps!

        There’s a video floating around of a midsized sedan from the 60s and the 00s in a frontal offset crash and the old car is absolutely demolished.

          This is a consistent argument I get into with my mother. She complains that cars are made of plastic now, and I try to explain that crashing a steel body car would mutilate your body but to no avail. This and her hatred of roundabouts.

      that’s the kind of positivity I wanted. it is cool how much laser tech has improved in the past few decades

        Sure, they had more legroom because the modern concept of economy class did not exist. They also crashed and killed everyone onboard much more often

          It’s a fair point more affordable is also a kind of better, average Joe could only dream of affording flight. On the other hand it’s all new technologies and the price is bound to drop as adoption goes up. You could argue windmills have been around for a while, but let’s be honest - calling a windpowered electricity generating turbines windmills is a bit of a stretch.

            It’s a combination of things to be sure. To give a simple example though, turbine engines are inherently much less likely to quit running than piston engines.

            • Airline comfort has drastically and steadily declined over the past couple decades, long after commercial airlines started using jets. Maybe not to the level of that first picture - cattle class has been around since I was a kid - but passenger comfort has been measurably squashed just in the time I’ve been travelling as an adult. Safety hasn’t correspondingly improved as a result of technology in that time.

                Safety has improved considerably in the past couple decades in the USA.

                There’s probably no causal relationship to declining comfort though. Comfort has decreased for two reasons:

                1. Anything that gets more seats on a plane increases potential revenue. An extra row in a 737 could be on the order of $2 million a year in revenue.
                2. Any discomfort the airline can inflict that doesn’t significantly exceed its rivals encourages customers to pay for upgrades.
                • But, again, most likely due to more stringent maintenance, training, and procedural regulations thank because of any technology improvement. American’s average plane age is 11y/o; United is 14 y/o; Delta’s average plane age is 17 years old. Despite bring nearly half again older, Delta’s safety record isn’t much worse than American’s. There’s little or no correlation between fleet age and safety, and it’s more rational that any increased accident rate of older planes is due to wear and tear and general ages of the planes rather than the technology in them.

          I’d gladly trade leg room for a somewhat increased risk of death.

          That would be “made better” to me.

          Better is a useless metric.

            I understand your sentiment. On the other hand, I would rather my son have an hour of slight discomfort but arrive safely than be a fatality statistic.

            There is a feasible middle ground that is not realistically going to happen however. Slightly increasing personal space and comfort in the newer, safer planes without squeezing every possible seat in in the name of profit.

            “Better” does need to defined to not be ambiguous. To me a good definition to use in this thread would be “the net changes over time are objectively an improvement for the use”. I think that my middle ground would firmly be “better” but in the current state it is only strictly better for those owning the planes.

            They sold flight insurance, life insurance policies you bought at kiosks in the airport, into the 70s. No thanks.

        Air travel was very expensive back then relative to the average household income. If you’re willing to pay for business class today, you’ll be basically in the same position as those folks in the first photo, and be paying about as much (relatively) as they did.

        It’s still available, but you’re not going to get it for the price of a super saver economy ticket. It’s an apples to oranges comparison.

        Fair points and nice illustrations 👍
        I was mostly thinking about fuel economy and decreased noise levels.

        I’m having a hard time believing the first picture is a real airplane. Are you sure it isn’t a mock up? The width of the cabin rivals the 787 I flew on from Japan.
