News from ArgonV: there is a new plane pack for Fighter Squadron W.W.I called Pioneers of Flight.
This is the very first release of a totally new Plane Pack for Fighter Squadron - World War One. As such, of course the contents within are considered Beta, and in an ever-changing state. Also, this release just includes the first 5 aircraft, with basic missions and ground units. In the future, we hope to offer more aircraft, varied ground units and even a new airfield designed for Pioneers of Flight.
