As the plane was destroyed at the first flight trial, what was left were photos made at Paris aeronautical exhibition, in 1910.
Reminding that Henri Coanda was then 26 years old, in the photo I am attaching there is the inventor, plus a man in his 30's, and right near Coanda, a young lady. Beyond them is the jet airplane and an interested visitor.
I am wondering who was the young lady. Even though the photo is unclear, she seems beautiful. I would name this "history's mysteries".

PS: I had downloaded the photo from Internet. I know that is not enough information, but the download was few months ago.
