WEFT is AircraftIQ's four-point recognition method — how it works.

History
The first prototype flew on 23 August 1927 and was lost in an accident during flight testing. André Herbemont then designed a further prototype with an inverted sesquiplane wing configuration.
Variants
Three were built. The S.91 never went into quantity production, but it was developed into the Blériot-SPAD S.510.
Where you'll see it
The French government dropped its interest in the light-fighter programme, so the S.91 did not enter service. The S.510 that followed was the last biplane produced by the French aviation industry.
