Genuine academic curiosity. I wish that I hadn't asked the question because I now realize that I was dumb. I totally misinterpreted what the commentor meant. When they said "the one that was the jet over the turboprop", I somehow thought they meant "the plane with the turboprop engine having the intake on the top, as opposed to bottom, of the propeller". No idea why I thought that.... Now, though, I wonder if those exist...
