You Won’t Believe These Planes Never Made It To Production

Miles M.39B Libellula – 1945

The goal for this WWII experimental craft was to give the pilot an optimal landing view on aircraft carriers. The M.39 followed the M.35 by the same name, but M.39 housed a twin engine. The M.39B was the proof of concept model, which the Brits approval for production, but then changed their minds. The prototype suffered two accidents so they canceled the order.
