1994 - First flight of the Bell 430
Our latest featured aircraft for October is the Cierva W.11 Air Horse .
The aircraft was designed to provide viable heavy load lifting capability for commercial operations. It employed 3 main rotors all rotating in the same direction. Torque offset was provided by thrust components from the 3 rotors through built-in shaft tilt. The aircraft had a semi-monoquoque structure, a single engine, and a long-stroke undercarriage (5ft) to cope with high rates of descent. A description of the aircraft and its characteristics can be found in the following references,

Map locations for milestones
The aim is to provide an exact location for each milestone in the database. In many cases this is not possible and all we can provide is the nearest possible, general location (usually a town instead of a specific location). The map view provided is normally chosen to provide detail of the location as well the general area to provide overall geographical context. We always welcome feedback on the accuracy of the map locations provided.
