Macchi M.19
The Macchi M.19 was a 1920s Italian single-seat racing flying boat designed and built by Macchi for the 1920 Schneider Trophy race.
Development
Based on the earlier Macchi M.17 racer the M.19 first flew in August 1920. It was designed to meet a new Schneider Trophy rule that each competitor should carry 300 kg (660 lb) of disposable load. It was a single-seat biplane flying boat with a 490 kW (650 hp) Fiat A.14 engine strut-mounted above the upper wing, driving a four-blade propeller in tractor configuration. Early test flights showed a torque reaction from the powerful engine and the hull and rudder had to be redesigned. This resulted in the M.19 missing the 1920 Schneider race. The following year the weight rule was relaxed. In the 1921 race, the M.19 competed against two M.7s, but the M.19 had to be withdrawn after the 12th lap with a fractured crankshaft which ruptured a fuel line, causing the aircraft to catch fire.

M-19 (Michigan highway)
M-19 is a state trunkline highway in the US state of Michigan. The trunkline begins northeast of Detroit at a junction with Interstate 94 (I-94) near New Haven and runs northward to a junction with M-142 just east of Bad Axe in The Thumb region of the Lower Peninsula. The highway runs through mostly rural and agricultural areas, connecting several small communities.
Dating back to the original signposting of the state highway system, M-19 initially connected Detroit with Port Huron and Port Austin in 1919. In late 1926, the routing was altered to shorten it to Bad Axe on the north and Richmond on the south. Additional changes in the 1950s and 1960s updated the highway to finish paving the roadway and extend it southward to its present terminus.
Route description
M-19 begins at a junction with I-94 near New Haven at the interchange for exit 247. The highway runs to the northwest along New Haven Road into town where it turns northeasterly on Gratiot Avenue to run parallel to I-94. Outside of New Haven, the landscape along the highway is composed of mostly farm fields on the way to Richmond. Once the trunkline enters that city, it turns northwesterly and then northward along Main Street before exiting town. Continuing north, M-19 travels through mostly rural areas and agricultural fields and continues as such, through the community of Memphis. The trunkline crosses out of Macomb County into St. Clair County in the middle of town. M-19 crosses the Belle River and continues to a junction with I-69 at exit 184, about 15 miles (24 km) west of Port Huron. From here the route continues north, passing through the small, rural community of Emmett, where M-19 crosses a branch line of the Canadian National Railway that also carries Amtrak's Blue Water passenger route.
