Messerschmitt M35

During 1927-33, Messerschmitt designed a series of six sport planes, the single-seat M.17 and M.19, and the two-seat M.23, M.27 M.31, and finally the M.35. With the exception of the M.23, none sold in large numbers. They were all single-engine low-wing cantilever monoplanes with open cockpits and fixed undercarriage. The M.35 kept the extended fuselage of the M.27 and combined it with an undercarriage of single leg, spatted form.

Two different engines were used. The M35a had a 112 kW (150 hp), seven-cylinder radial Siemens Sh 14a, and the M.35b a 100 kW (135 hp) four-cylinder inline inverted air-cooled Argus As 8b. The former was the shorter and faster of the two. The aircraft first flew in 1933.

The aircraft was first shown to the public and potential buyers at the 1934 Aerosalon in Geneva. In that year, Rudolf Hess won the Zugspitz trophy in a M.35. In 1934-1935, Wilhelm Stör won the German Aerobatic Championship in a M.35b, and in 1935 the women’s prize was taken by Vera von Bissing in a similar machine. Stör can be seen flying an M.35 in daring acrobatic maneuvers during the 1935 German film Wunder des Fliegens (Miracle of Flight).

Despite these successes and strong performances at other venues in the late 1930s, only 15 M.35s were built, 13 registered in Germany, one in Spain and reputedly one in Romania. Though the M.35a was faster, the M.35b was commoner; only two M.35as are definitely identified.

Messerschmitt M20

Developed from the M-18, the first M20 prototype flew on February 26, 1928, and crashed on its initial flight killing the pilot Hans Hackmak. The second aircraft flew on August 3, 1928.

There were 3 models: a,b, and b2.

13 aircraft went to DLH and one to DVS. A number of crashes led Lufthansa to refuse to accept any more M20s, which resulted in the Messerschmitt company, Bayerische Flugzeugwerke (BFW) going bankrupt on 1 June 1931.

Eight survivors went to the Luftwaffe as trainers, the last one crashing in 1943. One was sold to Varig in Brazil in 1937 and flew on to 1948.

Messerschmitt M19

Designed by Willie Messerschmitt especially for the Sachsenflug sports flying event held at the Leipzig-Mockay airfield from 30 August to 5 September 1927. Two examples were built, at least one powered with a Bristol Cherub II engine. Both aircraft won the Sachsenflug and some 60,000 Reichmarks in prize money.

Merx Fünfdecker Himmelsleiter

Built and demonstrated at Flugplatz Johnannisthal in 1911, but apparently did not fly. Later, the machine was modified, and it appears questionable whether the revision flew either. The secretive Merx had the “Himmelsleiter” (sky ladder) built and kept in its shed – hidden from prying eyes. When the first flight test was to take place, it turned out that the apparatus was higher than the door and could not be pulled out of the shed. Also known as the Mehrdecker-Versuchsflugzeug von J. Merx, (multiplane-experimental).
