1. propeller nearly double the efficiency of flat blades other contemporary experimenters used
2. a special engine that had about double the horsepower to weight ratio of any other engine at the time
3. a wing shape designed in a wind tunnel rather than seat-of-the-pants "bird shapes"
4. a 3 axis control system that worked
5. a research and development program that first identified the problems and solved them one by one with a series of prototypes
6. every modern airplane can trace its design back to the Flyer, and no other
7. the Flyer exists and can be examined
8. exact replicas of the Flyer have been made, and they fly like the Wrights documented the way theirs flew
it's pretty clear that none of the other "first flight" claimants have much of a case (especially since none of their alleged machines exist and can be examined).
Edit: an excellent example of a modern canard would be the Rutan LongEZ and it's accompanying, rather ridiculous, performance numbers: https://en.wikipedia.org/wiki/Rutan_Long-EZ
Curtiss put canards on his racing airplanes, because he copied the Wrights. On one race, the pilot hit a fence and damaged the canard. He cut off the wreckage and rejoined the race. He then told Curtiss that the airplane flew better and faster without the canard. Curtiss immediately pulled them off of his other airplanes.
A bit about active controls for canards: https://en.wikipedia.org/wiki/Canard_(aeronautics)#Computer_...
I don't doubt that the Wright Flyer was unstable though. Canards are kinda picky about angle, airfoil, and aspect ratio so if you don't fully understand the system as was the case at the time, it can lead to some problems.
"The paper shows that the 1903 Flyer was readily controllable about all axes but was intrinsically unstable in pitch and roll, and it could barely be stabilized by a skilled pilot."
> Thus, it did not exceed the stick free neutral point and it is static stable for the entire operating envelope of the aircraft.
It looks like the canard design in the paper is stable, and the blanket statement that canards are unstable is, as yet, unsupported.
Or make a paper airplane and toss it backwards.
Or buy a toy glider and launch it backwards.
They are unstable.
EDIT: WalterBright edited his comment to add examples and commentary after the arrow example. IOW, he added:
> Or make a paper airplane and toss it backwards.
> Or buy a toy glider and launch it backwards.
> They are unstable.
after I replied. His original comment was just:
> Try shooting an arrow with the feathers in the front :-)
A shitty move. I'll only address the "launch it backwards" comment, as the remaining bits are even more idiotic.
A canard airplane is not simply a backwards airplane. The criterion for stable forward motion, in pitch, is that dCm/d_alpha is negative, where Cm is the moment coefficient, and alpha is the angle of attack, and that the center of gravity be ahead of the center of lift. A "reversed" airplane, in either conventional or canard configuration, would have the center of gravity behind (in the new direction of travel) the center of lift, and would therefore be unstable.
Yaw stability is obtained by the vertical stabilizer exerting a moment opposite to the current yaw, by virtue of being behind the center of gravity and center of lift and, when yawed, being angled toward the midline of the aircraft. This is why, on a canard craft, the vertical stabilizer(s) are at the wing tips, or behind the center of lift and center of mass. A reversed aircraft, in WalterBright's imagination, or at his desk--It is difficult to trust anything he says, at this point.-- would have its vertical stabilizer ahead of the centers of lift and mass, and therefore destabilize the aircraft.
These two, that the center of mass is behind of the center of lift in the reversed configuration, and that the vertical stabilizer are ahead of it, are the actual reasons that WalterBright's toy glider, surprise, prefers to fly in the direction for which it was designed.
(He mentions the glider at his desk in his reply to this comment, which I will reproduce here, in case he deletes it: "I have a glider in my office. I launched it backwards. It promptly flipped over and proceeded in the normal direction.")
It would be interesting if, for example, WalterBright could produce a discussion from, say, Aerodynamics, Aeronautics, and Flight Mechanics, by Barnes W. McCormick, for example, warning the unawares aeronautical engineer in training of the dangers of the supposedly unstable canard aircraft.
The discussion above is all elementary flight mechanics, of which WalterBright would be aware if he'd had any training, or any expertise. Contrary to his repetition, his intuition does not suffice, and will not overturn these facts.

Take a wing shaped piece of card or balsa and attempt to fly it by itself. You will find that it rapidly pitches up and stalls, flips over on its back, and repeats the process as it flutters it the ground. You can prevent it from doing this by taping a pole sticking to the front - a pencil, perhaps - as a counterweight to the pitch-up moment. This arrangement flies, but is very difficult to trim and has a tendency to suddenly invert as soon as the angle of attack goes negative. To stabilise it, all you have to do is put a small horizontal surface on the end of the pole. You have made a canard glider.
(If you actually try this, you will also need some vertical stabilisation.)

The reason the Wrights built their own engine was they wrote to several engine manufacturers with a specification that they all turned down as unbuildable.
So their engine was groundbreaking, though it may not have been the first. I don't know anything about the provenance of the Langley engine, except that it's clear he had to build his own engine, too.
More to the point, where did the engines for the other first flight claimants come from?
> There was no manufacturer that created an engine which was as light weight as they needed. They undertook this enterprise themselves as well. The brothers asked one of their employees, Charlie Taylor, to build them an engine. Taylor built an engine in six weeks with an aluminum block to meet weight requirements. In their rough sketches given to Taylor, the brothers stated they need an engine to produce 8 horsepower. Charlie’s engine produced 12.
For example, his development of the multiplex telegraph did not seem to show evidence of understanding electricity, just an awful lot of tinkering.
Other aeronautical contemporaries of the Wrights exhibited little understanding, and a lot of tinkering, which is why the Wrights were able to leap so far ahead of them.
Even before then, Ismail al-Jasri fits precisely into this category.
The Wright Brothers also added to the canon of bicycle design and engineering, with the left-hand and right-hand thread. They deeply understood how 'nuts and bolts' worked in order to solve a problem of the pedal and chainset of a bicycle falling out over prolonged usage, even if the bolts are done up tightly.
Try and service a modern bicycle and when it comes to taking the pedals off you will only be able to do so if you appreciate left-hand and right-hand threads. The pedal on the left-hand side of a bike unscrews normally, the pedal on the right hand side needs you to unscrew it by turning the other way to expected, clockwise removes the pedal instead of securing it.
Although a small innovation compared to building a whole plane, this left-hand/right-hand thread could have been devised by others, however it is the Wright Brothers that got there first, demonstrating their deeper understanding of how things are made and put together.
Practically every auto manufacturer got started with bicycles instead of 'horseless carriages with horses'. The bicycle workshop is not recognised for what it is, the cradle of innovation and lightweight engineering (that contrasts with the 'big iron' of steam engines and what went before in the Industrial Revolution). Some of this innovation is just in little things like having standards, e.g. the 9/16" diameter of the screw on bicycle pedals. A lot of these things needed to be sorted out so that other things could be made.
And as an exercise to the reader, if you think carefully through relative rotations of each pedal compared to its shaft, shouldn't it be the right side pedal that goes on/off wrong!? Why on earth is it the left one?

Around the start of the twentieth century, many people started coming up with more-or-less viable designs. Nowadays we all agree the wrights were first. Others came up with designs in the same period (but probably later) . The fact that the wrights were(considered) first in the face of some pretty stiff competition actually makes it all the more impressive!
In fact, the Smithsonian maintained that one Samuel Langley was first for quite a while! Technically he did have a heavier than air machine airborne as early as 1896, though that one was not piloted. I think the Smithsonians' position (together with Glenn Curtis) had more to do with a desperate need to establish Prior Art in the US patent war that followed.
History does show that when the USA joined WWI, they were forced to start out in French and British combat aircraft. They had definitely squandered their lead by that time.
I'd also question point 6 somewhat ("every modern airplane can trace its design back to the Flyer"). In many aspects, modern aircraft in fact seem to differ markedly from the wright design, even to the casual observer. They lack canards and wing warping, and tend to be of a "puller" design.

Open Technology and the Early Airplane Industry Peter B. Meyer
When news of the Wright Brothers flight was confirmed Bell suspended all operations. Glenn Curtiss thought there was excellent potential for a business competitor to the Wright's but Bell wasn't interested. So Curtiss went back to Illinois and started his own airplane company now known as Curtiss-Wright.
The US government even ordered Lockheed to cease work on their jet engine and concentrate on piston engines:
"Lockheed had tried to produce a turbojet in 1940. Research engineer Nathan Price designed the startlingly advanced L-1000 with two-spool axial compressors aimed at a p.r. of 17 plus an afterburner, but when President Robert E. Gross took the brochures for the L-1000 and the L-133 canard fighter to be powered by it to Wright Field in 1942 he was told 'Forget it, keep building P-38s'."
"The Development of Jet and Turbine Aero Engines", Gunston, pg. 143
The DC-3, privately developed, was foundational for Army Air transport in WW2. The 707 was also entirely privately developed, and was foundational for all jet transport since. The Supermarine Spitfire of WW2 came from technology developed for Schneider Trophy races in the 1930's.
internet - the first internet was the telegraphy network, privately developed.
www - is not the first internet. BIX, Prodigy, CompuServe, MCIMail, RBBS, Timenet, etc.
It's not obvious that this was the wrong answer. The Germans were the first to field a combat jet aircraft, but it didn't help them much. The U.S. didn't really need the help, by 1942 it was already producing twice as many aircraft as Germany and Japan combined.
I think the real answer is "it's complicated." The jet revolution was not a single point event, and both government and private industry played a role.
Does anyone know if there is a similar, first person, written in the period, book about early aviation?
You sort of knew that bit was coming, but you can't really be prepared for that much hogwash that quickly.
First, they're obviously not a timeless example. A distinguishing feature of their time, compared to ours, is that there were no qualified aerospace engineers. Another feature is that the scientific and analytic culture was far more disjointed, immature, and parochial at the time. Consider, for example, fusion research today. No amateur will produce a burning plasma. ITER will. Because the scientific environment is more sophisticated, and is able to take on challenges outside of what amateurs can.
Second, they are not a prime example about the efficacy of a degree regarding "success," not least because n=1 in an endeavor riddled with variation. It's equally likely that they got very, very lucky, in spite of their apparent rigor.
Third, and finally, "[e]xperience, imagination, and courage" are not dichotomous with a "degree or title." It's not really apparent to me that, outside of the imaginations of sophomoric libertarians, that anyone believes that the world is stuffily dismissing outsiders who clearly have the facts on their sides in scientific and technical endeavors. Focusing on this fair-tale split between imagined elitists in their ivory towers and the pragmatic and gritty masses betrays a fascination with a staple of corny Americana, the garage workshop and its ilk. It's trite, predictable schlock.
I recommend reading a detailed account of their R+D program. They were not lucky. They did not randomly produce a flying airplane. They first identified each of the problems, and set about building prototypes directed at solving each of the problems one by one.
You could say that the Wrights invented the directed research and development process.
They were also unlucky in that they killed a passenger, but lucky that it wasn't rather than one, or both, of themselves. I realized that luck-minimizing framings are popular within entrepreneurial settings, and particularly in cultures where we're all "temporarily embarrassed millionaires," but it would be far healthier if we took on board the role that fortune plays in success. We would be, for example, far more heroic if we were facing odds, rather than a grind with a guaranteed success at the end.
Langley had 70 times as much money to spend, and his Aerodrome failed because it was underpowered, did not have enough lift, did not have an adequate control system, the wings were too flexible and would not hold their shape, the airframe was not strong enough for the loads, and the catapult tangled with the airplane and pulled it to pieces.
That's not bad luck, that's bad engineering from start to finish.
I think the jury is still out on this.
NASA's greatest successful decade happened shortly after they swept up all of the private organizations and talent from universities to form the organization. It's been said their efficient culture at the time reflected private industry culture that remained, combined with the rigour and scale of the job at hand found in university and government experience they had access to.
Everyone loves pointing to NASA 1950/60s accomplishments as the counter-point to private industry but basically just because gov finances something doesn't mean the positive effects of private industry can't still linger in government agencies well after they've been founded. Where the negative effects of top-heavy administrative machines, with endless risk-management and management-staff itself taking precedent over engineering talent (https://www.jerrypournelle.com/reports/jerryp/iron.html) have not yet crippled their R&D efforts.
That said, no one said gov isn't capable of great things but whether it's a sustainable repeatable thing as long-term large-scale organizations acting in a waterfall-esque process - I'm not so sure. The ideal is probably some middle ground where gov organizations can take an entrepreneurial style approach building small teams, while still providing them the access of gov resources and public-incentive structure, but without the damaging effects of administrative culture.
I'm not convinced gov contractors are the solution to this either due to the aforementioned public incentive structure and how it encourages graft, crony-capitalism, and poor oversight of public spending.
Not to mention context is incredibly important Fusion and the first humans in space are at a different scale than "first person to fly", given the amount of resources the Wright Brothers required. So again it's not black/white.
Perhaps it's a good thing that we still have plenty of diversity in organization so that we can try all possible options for how to do something. New, small, and inexperienced companies, large and highly organized companies, and government departments large and small can all try their hand at creating new things.
