Daniel what a great set. thanks for the pictures. Jim Kelley-Evens the pictures of the Scheinenzeppelin are really neat, keeping the passengers out of the prop would be a "customer relations problem" for sure. You know, the NYC (by my faulty memory) tried something similar in the 1960s, it used an RDC with 2 jet engines mounted high on the rear of the roof. Not sure what ever became of that thing, but I believe there were some toy models of it. Hard to remember today.
