What the fuck happened to aerospace tech since the 70s?

In the 70s, we had manned lunar missions, supersonic jetliners, multiple space stations in orbit, and reusable spaceplanes.

The fastest manned aircraft of all time (military or civilian) is the Lockheed SR-71 Blackbird from 1966.

Not only that but if you compare air travel in the 60's and 70's compared today, the experience is much, much worse today. A Boeing 747 from 1970 has the same max speed, similar range, and passenger capacity compared to today but with far, far less luxury.

What the fuck?

Space race fuelled funding and development, but that died down and no one cared much about aerospace apart from beating commies

Scramjets still violently detonate and fragment into a million little pieces and haven't even reached mach 13 yet. So that shit needs to get worked out before we can move on.

And also enormously more accessible and affordable.

For the most part, what has happened is incremental efficiency gains. Turns out passengers don't actually care about getting to their destination super quickly, and would much rather take a little bit longer and buy cheaper tickets. As for military stuff, most of the huge changes are under wraps.

For space, again, the name of the game has been efficiency and cost reduction as opposed to sheer power. It's difficult to truly impress upon someone how massive of an undertaking the Apollo program was. Remember that the US' space race was largely about pushing the science & tech to the absolute limit of what was possible to see where that boundary was, not set up any sustainable long-term presence or infrastructure. When the US did that, the world looked back and realized that to keep any of this shit going, it has to be sustainable and pay for itself. So everything when into optimization mode, which means starting from the small scale and working up.

With the success of the F9 and FH though, all that optimization and long-term planning that has been worked on is starting to pay off. The foundation is ready to go, now the industry just needs to start pulling off real projects from that foundation.

>The fastest manned aircraft of all time (military or civilian) is the Lockheed SR-71 Blackbird from 1966.
No, that would be X-15

At my old job we had a three seat row from a Lockheed Constellation in the lunch room. Most comfy chair ever, it even had ashtrays in the armrests.

Cold War ended no more competition in military technology development.

Also the fact that the SR-71 is technically the world's only aircraft thats ever came close to a combined-cycle engine that ever went into production. (Turbojet cycle in subsonic and supersonic in Ramjet cycle in a single engine)

Yes, we prefer safer than faster

Not true. There were not low cost airlines, granted, but for normal flights, prices were about the same.

The X-15 was a rocket powered design from 1959 and only 3 were ever produced.

The space program was just geopolitical dick-waving and we do that in other (cheaper) ways now. The shuttle was only reusable for a very loose definition of "reusable", and really only happened at all because of the sunk-cost fallacy - everyone involved kept pushing the useless thing forward because they didn't want to admit they'd made a hash of things. The SR-71 was made obsolete by satellites. In any case a lot of military recon these days is better served by predator drones than by SR-71s OR satellites. Air travel in the 60s had nicer service but a wallet-busting price. Sure you didn't pay extra to check a bag, but the ticket cost $1500 in today's money to begin with. Supersonic airliners never happened because of a.) sonic booms, and b.) the fact that they'd be much more expensive per passenger-mile to operate even with cheap 60s fuel, and since subsonic airliners are already fast enough to get you anywhere on the planet inside of one day, there wasn't much demand to make it faster still. Unmanned probes are still a thing, they just don't get prime-time TV coverage anymore. Go to theregister.co.uk/science if you want to know what's happening with space this week.

No, a modern Airbus A380-800 is far bigger [more passengers], can carry higher loads and has a lot more range.

Basically wrong on all counts. And tickets got cheaper.

I don't believe for a moment that SpaceX's success has anything to do with 'optimization' that has taken place since the 70s. Most of SpaceX's stuff is Apollo-era tech, kerolox rockets, pintle injectors, etc. Maybe small gains from switching to Al-Li for the tanks but nothing major.

Space technology simply did not advance much between 1970 and 2010, for geopolitical and economic reasons.

Concorde was a shitheap of national pride that never turned a profit, SR-71 was prohibitively expensive and replaced by satellites + possibly interceptable by MiG-31s. Commercial flights became affordable and the process killed the luxury

Concorde didn't end because of the crash. The planes were 35 years old and Airbus was going to stop making spare parts for them. British airways at least always made money from Concorde, though the fuel use meant the plane was entirely marketed as first class.

To answer OP's question, a decline in public sector projects to advance civil society at the behest of a burgeoning anti-state philosophy to curtail the extent of government and its taxation and public sector investment to allow for increasing wealth return of the economy to the capital classes and copious propaganda to that effect.

This guy gets it. Nice dubs.

incomes were much higher then too

it's shut down because the earth is flat user
it cannot be allowed for average human to go here
that's why they stall this industry

SR-71 was retired due to arms reduction treaties allowing Russians and Americans to fly spy planes over each other to verify quantity and location of nukes (it's politically obsolete). 747 is now retired by probably everyone other than Air Force 1. Fuel got expensive, so economy flights for everyone.

Space X made some things cheaper, but rocket technology will always be to expensive to bring about a space age, we need something that escapes the pull if gravity instead of fighting it.

Yep. I learned about this in business class. Then a new technology comes along which disrupts the current status quo.

ie teleportation... can you imagine what would happen to the transportation industry if tech like that became viable? 90% of it would go out of business.

Hold a hula-hoop up to your eye level and you will see curve too.

Simple 3D modeling disproves globe earth belief that what you see from altitude happens on a sphere ball. Not to mention NASA's own pics well below 110,000 feet show extreme curvature even on non wide angled lense cameras which can not explain or conicide with what is seen on independent footage.

Also ground measurments prove you can see farther than the sphere earth dictates you can. You can see cities, islands, mountains etc when they should be well below the curve of the Earth. Or do you disagree with this point?

In large part, the space program was a way to fund the nuclear arms race with the support of the American people. If you can build a rocket to send people into space, you can send a warhead too. If you can send communication satellites, you can send targeting and tracking satellites too. Getting men to the Moon is a way to say "fuck you, we can put weapons platforms on the moon."

It shouldn't be surprising that after nuclear weapons develoent hit it's zenith, funding dried up for NASA too.

Not a flat earther but that footage is shot with fish-eyed lenses, you can tell by the inverted curvature of the horizon at points within the footage, not to mention that the highest altitude a weather balloon can fly is nowhere near the boundary of the Earth's atmosphere.

Flat discs have curves like dinner plates or frisbees. If you to hover above one on a micro scale you would be able to see curvature much like in the independent film of space.

More like financial incentives for innovation. Aerospikes would greatly increase rocket efficiency if private companies wouldn't lose money developing the tech.

No matter what type of lens is used, the altitude is still far too low to see a curve.
Compare your photo with pic related, try and point out any individual mountain peaks you can see here.
Flatfags simply don't realise the scale of the Earth, much like Columbus but without the excuse of ignorance when utilities such as the Internet exist.

It's not terribly simple, you still need to model the earth and pick how you want to simulate optics.

It's an oblate spheroidal. A somewhat "squished" sphere.

You can't see anything that is "well below" the curvature of the earth, so there is nothing to disagree with.

You can even see that very strongly from the other camera that is visible in the image.

Did you watch the linkage though? It's shown what happens as the camera rocks up and down, when the center of the image is above and below the horizon line.

Whether you got a stereographic, equidistant, equisolid or orthographic fisheye lens with this or that extra distortion, you can tell how the actual shape looks once the camera moves like that.

Which leads only to a handful of instances that "prove" earth which isn't really proof because these images can be faked then and now and like I pointed out show flaws like having only 1 continent in daylight with 49% of the earth visible (one side of a sphere at that distance (you can never truely see 50% of a sphere)) while there are missing continents in that image.

In the video, the guy conveniently acts as if the photograph depicts the light disappearing immediately beyond the horizon, which would only be true should the photo be taken at noon, which it isn't as shown in the video.
Not to mention the positioning is all wrong, the eastern horizon of the blue marble ends at India, yet the guy claims that he should be seeing western Australia, which is several thousand miles to the east of the physical horizon.

Yes and any honest person would admit that viewing a round image from space does not constitute proof of a sphere rather it could also proof a flat disc. The other step is to realize that what you see rising up from earth isn't what you would see rising up from on top of a sphere.


>It's an oblate spheroidal. A somewhat "squished" sphere.

This has nothing to do with the conversation. An blate spheroid squished at the bottom as Neil Degrasse Tyson says is anagalous to the Sphere Earth. The differences are so minute it's not even a topic, and in their own (faked and photoshopped) pictures it shows what can be described as a perfect sphere easily.

One image isn't enough for proving the geometry of anything, but a flat disc is will not work when you see curvature in all directions and do so regardless if you're in a place that currently has sunlight or a place that currently is at night.

The reason why you can have night and day zone shaped as they are as well as have curvature in all directions is because earth is a spheroid, not a disc.

> So what are you going to say when I prove you wrong?
I figure you'd know better, being in the position where overwhelming proof and scientific consensus is currently against you even when you account for all data available.

Too bad there's video with stabalized gyro/gimble? stabalized cameras that debunk what you're suggesting

>not to mention that the highest altitude a weather balloon can fly is nowhere near the boundary of the Earth's atmosphere.

This is missing the point. Scientists/NASA will tell you can see the earth curvature around 50,000 feet with 35,000 feet being the lowest (with no proof just theory?) Weather balloons can go well above this and well above this at up to 170,000 feet or so. More than enough to see abundent curvature but instead you see minute curvature that can be attrivbuted to a flat disc

What part don't you understand? That image doesn't show up the correct percentage of Earth that should be lit up by sunlight. You can't scapegoat and say because it's a closer shot because they gave the distance and the whole premise of it being a whole photograph is that it HAS to be a certain distance away which would mean the shot would have half the earth in it.

You work in shit NASA gooch-licker. The aerospace industry is one of the most comparmentalized industries on earth and most of the "engineers" do menial tasks that a trained mexican can do like building components or have nothing to do with actual space or like all the people standing around in a control room doing nothing.

> with no proof just theory?
No you dolt, it's just some engineer saying that you could measure it on a photograph or something because now you have a decent bunch of pixels of curvature that is visible. [Obviously AFTER correcting your lens.to theoretically represent a straight line at the horizon as perfectly straight].

If you did it with just 1km horizontally in view, you couldn't even tell if it's just an attribute of your terrain (hilly?) and the curvature also wouldn't be visible enough on a photo - who the fuck knows what happened if it's just two pixels higher in the center than on the sides. You need to see a larger span.

>ut a flat disc is will not work when you see curvature in all directions and do so regardless

Lmao what are you talking about, flat discs curve in a ll directions

>The reason why you can have night and day zone shaped as they are as well as have curvature in all directions is because earth is a spheroid, not a disc

Wrong you can have night and day on a large area with a small sun like a simple concept like pic related (which most flat earthers don't hold as true but a simple example)

Or it could be more complex like
youtu.be/5m8rywmzdXE (jump to 13min 40 seconds) with mapping out azimuth and declination of the sun which is getting closer to a true mapping of the flat earth sun pattern.

>being in the position where overwhelming proof and scientific consensus is currently against you even when you account for all data available.

Most scientists have no clue, even Astrophyscists like Neil Degrasse Tyson didn't understand the science behind their own globe earth and he consistently said wrong things until recently. I would say 99% of scientists had no clue 5 years ago, now after flat earth maybe 95% don't have some clue with the rest thinking they have it figured it out when they don't.

Anyways here is Toronto being seen over 30 miles of water from a sea level (0 elevation) viewer height 6 feet, when it should be under 600 feet of curvature.

No you dumbass, it was liteally some popscience magazine that came out with the number 35,000 and posted no proof of being able to see it at 35,000 feet. Meanwheil NASA says it's 50,000 feet and Neil Degrasse says it's 60,000 feet.

You're missing the point though that a weather ballon goes well above these figures at 100,000 feet plus and show a lack of curvature

>Lmao what are you talking about, flat discs curve in a ll directions
Not evenly at all.

The closer you get to the edge, the more uneven the curvature "behind" and "in front" of you get.

If you stand right at or fly above one edge, there is no curvature in front of you and the curvature behind you is extreme.

> Wrong you can have night and day on a large area with a small sun like a simple concept like pic related
That's NOT in the shape of real earth day and night zones, and again, your horizon will not even NEARLY look evenly curved when you look around you flying above some point like the one that is in the center of illumination on your image.

> Most scientists have no clue
Wat? I mean, yea, social sciences and humanities don't, but... wat?

> Anyways here is Toronto being seen over 30 miles of water from a sea level (0 elevation) viewer height 6 feet, when it should be under 600 feet of curvature.
Toronto's center is nominally 76 meters above sea level plus then you have building height. And sea level is an estimated average between high and low tide.

And YET on the very YT preview image you see the lower parts of buildings being "cut off" by the horizon line... guess what happened? There are buildings lower than the nominal city center (near the sea?) and their lower parts are behind the horizon...

It's just me one guy. But you should be so lucky to be in my presence. You are talking to a highly developed level 86 Warlock conspiracy theorist. I know all the who's who and what's what of the conspiracy world. The possibility of flat earth is there and the evidence for round earth is miniscule but so is the proof of flat earth is still in it's infacy. It can go either way to be honest but that's still a major blow to scientific dogma of all correctness in their knowledge. Flat earth has already shat all over mainstream science credibility and exposed it as weak and emotion based with a totalirain mindset at it's current state.

That happened a lot during the cold war.
