SIA is not the name of the plane, it is the name of the company which built it:
Société Industrielle d'Aviation - Etablissements Delaunay-Belleville, with premises at Angers and St Denis.
[font=arial, sans-serif][/size]It had expertise in construction out of Duralumin alloy. [/font][font=arial, sans-serif]Henri Coandă worked there during WW1[/font].

[/size]I wonder if the plane is their entry to the 2Bn competition ?
