" though I don't know what I said that suggests that"
you didn't but you did say its not American or Indian, we knew nothing like that has been built in Europe.- didn't look Russian or Chinese........... about the only country left that builds anything serious is Brazil
So if it ain't there ........... it had to be a country with some military ambition & some hi-tech capability - I started with Argentina, then Chile, then Indonesia then.......... the list is long
Tho TBH it was BSD's "helicopter" question that at least gave me an idea of what it might be conceptually - I sure as hell never though of a pusher engine tho!
