The larger aeroplane with the engineer Manly on board was first tested
on October 7 of the same year, but the front guy post caught in the
launching car and the machine plunged into the water a few feet from the
house-boat. In spite of this discouraging mishap the engineers and
others present felt confidence in the aeroplane's power to fly. What
would to-day be regarded by an aeronaut as a slight setback seemed at
that moment like a tragic failure. The fifty thousand dollars had been
exhausted nearly two years previously; Professor Langley had made as
full use as seemed to him advisable of the resources put at his disposal
by the Smithsonian Institution; the young men of the press, for whom the
supposed aberration of a great scientist furnished excellent copy, were
virulent in their criticisms. Manly made one more heroic attempt under
very unfavorable conditions at the close of a winter's day (December 8,
1903). Again difficulty occurred with the launching gear, the rear wings
and rudder being wrecked before the aeroplane was clear of the ways.
The experiments were now definitely abandoned, and the inventor was
overwhelmed by the sense of failure, and still more by the skepticism
with which the public had regarded his endeavors.
In 1905 an account of Langley's aeroplane appeared in the Bulletin of
the Italian Aeronautical Society. Two years later this same publication
in an article on a new Blériot aeroplane said: "The Blériot IV in the
form of a bird ... does not appear to give good results, perhaps on
account of the lack of stability, and Blériot, instead of trying some
new modification which might remedy such a grave fault, laid it aside
and at once began the construction of a new type, No. V, adopting purely
and simply the arrangement of the American, Langley, which offers a good
stability." In the summer of 1907 Blériot obtained striking results with
this machine, the launching problem having been solved in the previous
year--the year of Langley's death--by the use of wheels which permitted
the aeroplane to get under way by running along the ground under its own
driving power. The early flights with No. V were made at a few feet from
the ground, and the clever French aviator could affect the direction of
the machine by slightly shifting his position, and even had skill to
bring it down by simply leaning forward. By the use of the steering
apparatus he circled to the right or to the left with the grace of a
bird on the wing. When, on July 25, 1909, Blériot crossed the English
Channel in his monoplane, all the world knew that man's conquest of the
air was a _fait accompli_.
