Featured aircraft
Our latest featured aircraft for January 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,

Milestone dates
Wherever possible, the exact date of a milestone is provided. In some case, the exact date is not known and only the month and year are available. Wherever this is the case the last day of the month is used with a note in the description to say that the exact date is unknown. The last day of the month is used as a conservative estimate of the actual date of the event. In a few cases, there is conflicting data regarding the exact date and a note has been added to highlight the alternative date.
