[Cigogne]

The overturned aircraft No. 871 is not a Nieuport 21, but rather a development of the Nieuport 12 (Type 81, 82... etc) and is a two seater trainer. Look at the cabane struts and they are the same as on the Type 10 and Type 12 two seater aircraft. Also, the interplane Vee-struts are slanted outwards, a feature of the Type 12 (and 81, 82 variants). They are training aircraft from Romorantin.
