Windsock Datafile 92 - Hanriot HD.1/HD.2

The Hanriot HD.2 was a fighter aircraft produced in France during the First World War. The design was based on that of the HD.1, but the HD.2 was a purpose-built floatplane. It made use of enlarged tail surfaces and shorter wingspans with greater area. Like its predecessor, though, it was a conventional single-bay biplane with staggered wings of unequal span. The prototype had a twin pontoon undercarriage, with a small third pontoon under the tail. The third pontoon was later discarded on production machines, though.
