The PZL M-15 Belphegor
The Belphegor was the initial biplane built way back in the year 1972 by the Polish aircraft company WSK PZL-Mielec for agricultural aviation. Its sole purpose was to be a crop duster but as it turned out, the price of its fuel far outweighed any agricultural profits it may have yielded. It was a jet-powered biplane with strange looks and a relatively loud engine, was therefore nicknamed after the noise demon prince of hell, Belphegor.
