Grigorovich M-9

Grigorovich M-9 (alternative designation ShCh M-9, sometimes also Shchetinin M-9) was a Russian World War I-era biplane flying boat, developed from the M-5 by Grigorovich.

The first M-9 was ready in 1915 and its maiden flight was carried out on January 9, 1916 at Baku. On September 17, 1916, the test pilot Jan Nagórski became the first to make a loop with a flying boat.

During the Russian Civil War, M-9s participated in the air defence of Baku, dropping approximately 6,000 kg of bombs and 160 kg of arrows. The aircraft also carried out photo reconnaissance, artillery spotting and air combat sorties.

The M-9 was also used for the first experiments on sea shelve study, participating in the finding of new oil fields near Baku.

Nine M-9s were captured by Finland during the Russian Civil War. One was flown by a Russian officer to Antrea on April 10, 1918. It sank the following day during type evaluation. Eight more were taken over at the airfields at Åland and Turku. The aircraft were used until 1922 by the Finnish Air Force.

M9 (railcar)

The M9 is a future electric multiple unit railroad car to be designed for and ordered by New York's Metropolitan Transportation Authority for the Long Island Rail Road as part of the 2008–2013 Capital Plan. It will be built by Kawasaki Heavy Industries. The purchase of the initial 92 M9 cars is intended to expand the Long Island Rail Road's fleet size in anticipation of the completion of the East Side Access Capital project. The additional rolling stock will address the need for additional service to Grand Central Terminal and anticipated expanded service. The projected cost of developing, designing, and constructing the first order of M9 cars is $205 million. The MTA plans a larger additional fleet purchase at some point to replace the aging M3 railcars, beyond the scope of the 2009-2014 Capital Plan.

M-99 (Michigan highway)

M-99 is a state trunkline highway in the Lower Peninsula of the US state of Michigan. It runs from the Ohio state border, where it connects to State Route 15 (SR 15), north to Lansing, where it terminates at a junction with Interstate 496 (I-496) and the Capitol Loop. The highway mainly serves local communities along the route as it passes through farm lands in the southern part of the state. One segment is routed concurrently with US Highway 12 (US 12) in Jonesville while the northern end runs through urban areas on a street named for Martin Luther King, Jr. in Lansing.

The current highway is the third to carry the M-99 designation. The others were located near Lake Michigan near Muskegon in the Lower Peninsula and Gulliver in the Upper Peninsula in the 1920s and 30s. The current highway was first designated as parts of M-34 and M-64 in 1919. These numbers were later dropped in favor of an M-9 designation in 1929. For part of 1934, a loop route was designated M-158 in Hillsdale County that was used for a rerouted M-9 in the area. The M-99 designation was applied to the highway in 1940. Since then, the state has completed paving twice; one segment was returned to gravel surface for two years in the 1950s. The southern section in Hillsdale County was rerouted in the 1960s, and sections were converted into divided highways in the late 1970s.
