Bourgoin et Kessels

   Bourgoin and Kessels' big machine, Aerobus, had been registered for the Concours Militaire in 1911, but it did not appear until July 1912, when it was introduced at the Vel d'Hiv, the famous Velodrome d'Hiver, the winter cycling stadium in Paris. It was a huge uncompleted monoplane designed to carry 12 passengers in a boat-shaped hull slung between the great wing and the 4-wheel undercarriage. 2 engines sat on the rear axle driving 2-3.5-meter diameter tractor propellers through long diagonal shafts; a large fin and rudder hung at the rear between 2 shaft-controlled elevators.

   (Span: 14 m; length: between 12 and 16 m; length of hull: 5.3 m; wing area: between 60 and 100 sqm; empty weight: 900 kg; gross weight: 2200-2600 kg; 2-125 hp (perhaps 200 hp) Dansette-Gillets)
  
   In 1913 Bourgoin designed what he called a "parachute monoplane." The description, however, fitted the strange Lataste: horizontal and vertical propellers, a circular wing with variable angle of attack, 4 wheels and rudder. It is known the Lataste was built, but no other connection has been found so far between it and the Bourgoin.
