Glad you all enjoyed it!
What caught my interest particularly was recollection of comments by an early French military pilot, Capt. Ferber, well before the war, describing how he thought aerial combat would occur, likening it to two birds seeking to be the highest, so as to dive down upon the foe, and then if unsuccessful, strive again for height. This bird seems to have the same idea.
I had no idea the Germans used raptors to try and halt carrier pigeons, though it does make some sense. Nor was I aware birds of prey were such a regular foe of RC models. A shame Perry's Taube took such harm.
