All true, but easy for us to say 100 years after the event. Back then, all ideas carried equal weight until disproved. (Usually by meeting the ground abruptly) The British aviation historian, Charles Gibbs-Smith, made an interesting distinction about the pioneers of flight. He sorted them into two categories: the "Airmen", and the "Chauffeurs". The latter were sure that an inherently stable design could be found that required only that the pilot steer it in the direction he wanted to go. Santos-Dumont, for the most part, fell into this camp. That's why he designed the 14bis with the pilot standing up. The "Airmen", on the other hand, realized (in the words of one of the Wright Brothers) that flying was like riding a high spirited horse. It required constant attention and the ability to react instantly.
Brazil loves to replicate the 14bis in the hope of challenging the Wrights. It's here that Gibbs-Smith made another important distinction. He said there is "true flight" and "powered hops". The pioneers knew exactly what they wanted. They wanted to soar like eagles, not flutter like barnyard chickens. (the latter being uttered by Wilbur in one of his less charitable moments in France). Gibbs-Smith pointed out that 'powered hops' of several hundred meters were all well and good, but to claim 'true flight', a plane should be able (at a minimum) to take off, fly for 1/4 mile, make a controlled turn, fly back, make a second controlled turn and land at the starting point. This the Wrights did, and Santos-Dumont was gracious in ceding the laurels to them.
It's interesting to see the 14bis actually fly, and as far as I can see, better and longer than Santos-Dumont's attempts in France. I'll assume that it landed safely further on down that runway, but I'd really like to see it make a turn and come back.
