The only plane I have had attacked in the air was the Infamous Flamingoid, which is pink. I was doing a half hour thermal flight, and a couple of buzzards, of all things, took offense at the presence of a Flamingoid in their air and made repeated swoops at it. I did loops and stalls, and they eventually left. I got the half hour.
And for what it's worth, the same pink Flamingoid has been attacked several times on the ground by RC sailplane pilots. Go figure. RCSE-List facilities provided by Model Airplane News.
