Hi Alex,
You certainly have our greatest sympathies with your father's passing (and we're glad you're back).
As far as Knights of the Sky is concerned, the screenshots here show the continuous progress the development team has made towards their ultimate goal of final release. Their vision hasn't wavered, and the creative work on this project moves forward every day.
Starting from the ground up, and then having decided to create their own game engine, the development process has certainly taken longer than the KOTS team anticipated, but they have not lost sight of the endgame.
All we can do is be hopeful that the development process continues to move forward, oh, and that we see a pilot in that Fokker soon.
(btw, aircrews will be fully animated)
