Santos-Dumont in his second biplane, "14 bis," on which he made the first public flight in Europe, in 1906. This machine was of the "tail-first" type.

The picture shows the Santos Dumont "Demoiselle" of 1910, a tiny "Tow-pilot" monoplane of only a little over 16 ft. span. It flew somewhat erratically and was apparently a handful for its pilot.

This view shows how comfortably furnished are the dining saloons.

Few aircraft provide smoking facilities in as pleasant a manner as this.
