Blacksnake got it, it's one of the "flying vespas" and I think it was a "record plane" not a bomber though it evoved into the P32 bomber and some unconfirmed sources state they wanted to use one for a raid against New York in 1943. I had hopes for this one as the pic is the 850 hp Isotta Fraschini XI Asso powered early form and most pics existing are of the Piaggio P XI RC 40 radial engined later form. There is a picture of it in it's radial engined form that shows the cockpits a bit better, visibility at take off was probably non existent. three-engined monoplane | flight pdf | pdf archive | 2000 | 0549 | Flight Archive Over to you.
