2nd Lieutenant
With good weather, the airplane averaged 146 kilometers per hour (90.7 miles per hour) for 60 hours. The pilots initially ran the V-12 engine at 1,950 r.p.m., but gradually reduced that to 1,400 r.p.m., as the airplane burned off fuel and became lighter. On the third day, Bossoutrot and Rossi encountered strong winds and rain squalls, and at times the Blériot-Zappata's ground speed dropped to just 90 kilometers per hour (55.9 miles per hour).
At 10:35 a.m., Saturday, after 76 hours, 35 minutes in the air, Bossoutrot and Rossi landed at Es-Sénia. They had flown a distance of 10,601.48 kilometers (6,587.45 miles), setting a new FAI world record.² (They also exceeded their previous World Record for Duration ³ by 1 hour, 12 minutes, though no new record is listed on the FAI's Internet web site.)
The Blériot-Zappata 110 was an experimental long-range airplane ordered by France's Service Technique de l'Aéronautique, the government agency responsible for coordinating aviation research. It was designed by Italian aeronautical engineer Filippo Zappata and built by Blériot Aéronautique S.A.
A technical description of the Blériot 110 appeared in the National Advisory Committee for Aeronautics Aircraft Circular No. 138, which also contains many technical illustrations of the airplane's construction. The Blériot 110 was 14.57 meters (47.80 feet) long with a wingspan of 26.50 meters (86.94 feet) and height (to the top of its cabane strut) of 4.90 meters (16.08 feet). The wing had an area of 81 square meters (872 square feet). Its empty weight was 2,400 kilograms (5,291 pounds) and the gross weight was 7,300 kilograms (16,094 pounds).
The airplane's wing was built in three sections so that it could be disassembled for ground or sea transportation. The wing had two spruce spars with an oblique aileron support spar that increased its torsional strength but contributed to the airplanes overall light weight. The ribs were of plywood, braced by steel cables. The wing was covered with plywood.
The wing was braced by two steel struts on each side, and a system of wires above, connecting to the upper cabane strut, and below, to the fuselage.
The fuselage cross section was rounded at the top, narrowing to a single keel. It was built of frames and longerons which were then covered with three layers of diagonal 5 centimeter-wide whitewood strips, glued and nailed, each layer overlapping the one below at a 45° angle.
