Note that the first flight was also in 1903. According to the legend I've heard - this was published the day before the Wright Brothers first flight in Dec 17 1903. I didn't see the publication date in the article.
according to the first paragraph of TFA, the first flight was 9 weeks after the 1903 article was published
Nobody believed them until 1908ish, when they flew over crowds in France and could no longer be ignored.
