Chase YC-122 Avitruc

The Chase XCG-18A and YC-122 Avitruc (known internally as the Chase MS.8) was a military transport aircraft designed by Chase Aircraft and produced in limited numbers in the United States in the late 1940s, initially as a glider, but definitively in powered form. The design was based on the CG-14 cargo glider but was substantially larger and featured all-metal construction. It was a high-wing cantilever monoplane. The fuselage was of rectangular cross-section and featured a loading ramp at its rear. The main undercarriage units were carried at the sides of the fuselage and were fixed, while the nosewheel was retractable. In its powered form, two radial engines were fitted in nacelles in the wings.

Design and development

The USAAF's experiences with cargo gliders during World War II indicated a role for a similar aircraft in the post-war inventory, but one capable of carrying a substantially heavier load and with greater recoverability than the essentially expendable wartime wooden assault gliders. Chase's CG-14 was selected as a starting point, and in January 1947, the USAAF placed an order for an enlarged, metal version of this aircraft, initially designated XCG-14B but redesignated to XCG-18A to reflect the basically all-new nature of the aircraft. When the prototype flew that December, it was the world's first all-metal transport glider. One of the major improvements was the use of a thinner wing section which allowed high tow speeds and small aircraft like the P-47 fighter being able to tow it into the air and to its release point.

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.
