In May 1904, the Wright brothers just glided in front of journalists according to their own September 1908 account.
The brothers also said the newspapers in May 1904 "in kindness, had concealed" the reality, they had lied!
This is what the Wright brothers themselves declared in 1908 about their witnessed flight attempts in 1904:
"
In the spring of 1904 … the new machine was heavier and stronger … When it was ready for its first trial, every newspaper in Dayton was notified, and about a dozen representatives of the press were present. … When preparations had been completed … The machine, after running the length of the track, slid off the end without rising into the air at all. Several of the newspaper men returned the next day, but they were again disappointed. The engine performed badly, and after a glide of only sixty feet, the machine came to the ground. The reporters had now, no doubt, lost confidence in the machine, though their reports, in kindness, concealed it. Later, when they heard that we were making flights of several minutes' duration, knowing that longer flights had been made with air-ships, … they were but little interested."

And here you find what the newspapers wrote in May 1904:
"Flying Machine. Given a Successful Test by Messrs. Wright This Afternoon. Rose Twelve Feet in the Air and Sped Along a Distance of Twenty-Five Feet..Propellers Broke.", Dayton Press, May 26, 1904 (see:
Scrapbooks: January 1902-December 1908 | Library of Congress )
Did the brothers glide 60 feet in May 1904 or fly 25 feet?
Also in the Sep. 1908 article, the Wright brothers claimed that "
when they (the journalists) heard that we were making flights of several minutes' duration, knowing that longer flights had been made with air-ships, … they were but little interested." which is a big lie. They pretended the journalists had not been interested and this was the reason there was no serious witness for their flights in 1904 - 1905 when it was known the two inventors had refused systematically to show their planes or made public demonstrations before Aug 8. 1908.
