FWIW the Brits had a quadraplane and the Italians had a nonaplane
(enneaplane?). Neither were any good; the 9-plane crashed on its first
takeoff. Supermarine made the 4; Caproni the 9. The worst ever built
was the monoplane Christmas Bullet; they made two; on the first flight
of both they became 0-planes. the sad part was they were made and
flown sequentially. Why the second pilot ever tried to fly the second
bird is beyond me. The wings were flexible and could be pushed up and
pulled down by hand!

You wouldn't happen to have been reading Gilbert's "World's Worst
Aircraft"? Love that book.
