Aero A.42

The Aero A.42 was a Czechoslovakian bomber aircraft of 1929 that was only ever produced in prototype form. For its day, it was an advanced design, with a sleek monoplane configuration. However, the Czech Air Force was not satisfied with it for a number of reasons, in particular, the aircraft's take-off and landing rolls were felt to be excessively long, and crew complained about the cramped cabin. The air force suggested a set of modifications to Aero, including replacing the wooden wing with a metal one, but Aero discontinued development.

On September 20, 1930, one of the two prototypes set international speed records of 253.428 km/h over a 1,000 km (620 mi) closed circuit, carrying payloads of 500 kg (1,100 lb) and 1000 kg (2,200 lb).

One prototype was used by the Czechoslovak Air Force until 1938, then by the Slovak Air Force. Probably it was scrapped in 1940.

The A.42 was a single-engined high-wing cantilever monoplane, with a fixed landing gear.

List of County-Designated Highways in Michigan

The County-Designated Highways in Michigan comprise a 1,241.6-mile-long (1,998.2 km) system of primary county roads across the US state of Michigan. Unlike the State Trunkline Highway System, these highways have alphanumeric designations with letters that correspond to one of six lettered zones in the state. The CDH system was created in 1970 in response to the business concerns of a woman from Saugatuck. Her one-woman crusade in the 1960s started after the highway in front of her motel was turned over to local control as a county road and removed from state highway maps when the nearby freeway opened. After nearly a decade of efforts, the first two test highways were designated, one each in the Lower and Upper peninsulas of the state and included on the 1970 state highway map. The CDH system was created and expanded in scope c. October 5, 1970, after it was approved by the County Road Association of Michigan and the State Highway Commission.
