On April 18 in the history of vertical flight:
1951 - First flight of a gas turbine powered helicopter (Sud-Ouest SO.1120 Ariel III)
Featured aircraft
Our latest featured aircraft for April 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,

Titles for milestones
When creating a milestone that relates to an aircraft it is important to use the designation of the aircraft somewhere in the title e.g. Description of a milestone (Aircraft XYZ).
This then allows users to search for milestones related to a specific aircraft, when using the milestones search, as well as searching for specific events.
