Slowest Aircraft in the world...!!

PZL M-15 Belphegor

                    The aircraft was designed in Poland in response to a Soviet requirement for a new agricultural plane, for use above the very large areas of Soviet farms, the kolkhoz collectives, and state-owned sovkhoz.

                     The first variant of the M-15 was flown on 30 May 1973, and the second prototype on 9 January 1974. During the next few years it was intensively tested, along with a pre-production series. The M-15 was shown at the Paris Air Show in 1976, where it was nicknamed the "Belphegor" due to its strange look.

                   

The PZL M-15 is believed to be the world's only jet agricultural plane, the world's only jet biplane and the world's slowest jet, at least as far as aircraft that have been put in mass production.

                     The aircraft was a metal twin-boom sesquiplane, with a jet engine over the crew cabin. Part of lower wings and chemicals tanks were made of a laminate to avoid corrosion. The upper and lower wings were connected with two thick columns which housed the chemical tanks. The tricycle landing gear was fixed. The crew was a single pilot; two technicians could be carried if necessary. The M-15 was fitted with spraying and dusting gear, powered with compressed air.
