Looking at the Hog-Air site reminds me of the guy who drew up a
"Breezy Senior" with a Piper Aztec wing (the engine nacelle notches
skinned over) and a 8V71T Detroit Diesel turning what looked like a
cut down Sea Fury Dowty-Rotol five blader. He was a McDonnell-Douglas
engineer and his numbers actually looked good-of course it still only
had two seats and went 85 knots. The 350 hp, 2300 lb engine cut into
the useful load somewhat.
