MSrE M-21

The MSrE M-21 Harag (Hungarian: "Fury") was an aerobatics aircraft built in Hungary in 1936, sometimes known as the Szegedy M-21 after one of its designers, József Szegedy. It was a conventional biplane design with single-bay staggered wings of equal span braced by N-struts. The pilot sat in an open cockpit, and the tailwheel undercarriage featured divided main units. Only a single example was built.

M-21 (Michigan highway)

M-21 is an east–west state trunkline highway in the US state of Michigan connecting the cities of Grand Rapids and Flint. The highway passes through rural farming country and several small towns along its course through the Lower Peninsula. Following the course of a handful of rivers, M-21 also connects some of the state's freeways like Interstate 96 (I-96), US Highway 127 (US 127) and I-75. The highway is used by between 1,700 and 36,000 vehicles daily.

M-21 was designated along the highway by July 1, 1919 between Ionia and Goodells near Port Huron. Changes made in the 1920s extended it on the west end to Holland and on the east end to Port Huron. M-21 was truncated at both of its current termini as two Interstate freeways were completed. I-196 functionally replaced M-21 between Holland and Grand Rapids with a portion retained under state maintenance as Old M-21, now M-121. I-69 replaced M-21 from Flint to Port Huron. A section of M-21 through Flint became M-56. That designation was decommissioned in the 1980s when M-21 was returned to its former routing in Flint.
