I can't even believe I'm going to acknowledge this(especially some random "blog" that was posted as reference), but, as an active member of the
USAF, directly working with the F-15 day to day, I can tell you all of us in the F-15 community are very much a 'community.' We all know the
whereabouts of our other squadrons, have contacts in them, and DEFINITELY would know if one of our jets was downed, whether it be by accident, or
hostile fire.
Now much of Kosovo was fielded by the 48FW, namely the 492nd FS(F-15Es), and 493rd FS(F-15Cs, with 4 MiG kills during that conflict). I have personal
friends that were there, based with these jets in Aviano, and Cervia, Italy, as they conducted their missions in the conflict. To put this to rest,
NO F-15s were lost to air-to-air combat. It just didn't happen. There isn't a BBC article stating this, if there were, it wouldn't be so
difficult to find. The F-15 is not an aircraft we would "hide" being shot down regardless. If one was lost, it would be easy to determine its
squadron, base and tail #. Let's please put this to rest.
