J.Herris Friedrichshafen Aircraft of WWI (A Centennial Perspective on Great War Airplanes 21)

Friedrichshafen FF9

   With the FF9 that first flew in June 1913, Friedrichshafen returned to the pusher configuration. The FF9 strongly resembled the earlier FF1 but was larger and more powerful, using a 135 hp NAG six-cylinder engine. As with the FF1, wheels could be attached to simplify ground handling.
   Pilot Dahms flew a long distance course from Manzell over Basel-Cologne-Amsterdam-Emden to Hamburg in the FF9 during the period 20-23 September 1913. However, in Blankensee the plane crashed and was badly damaged, Dahms and his passenger being injured. The FF9 was repaired and on 12 November was flown to a new world endurance record for biplanes, flying for 6 hours, 16 minutes, and 30 seconds. Like earlier Friedrichshafen aircraft, only a single example was built.

Friedrichshafen FF15

   The next Friedrichshafen aircraft design to be built was the FF15, an aircraft that owed much to the earlier FF1 and FF9. The FF15 was an improved FF9 and used the same 135 hp NAG as the FF9; other specifications were very similar.
   Pilot Truckenbrodt flew the sole FF15 at the 1914 Bodensee Competition.
