the plane got shot down due to good scouting actually. the serbs had spies watching us planes take off and land and knew exactly what was in the air and when to expect it. they knew there were no f18s nearby which could attaack their aa positions more rapidly. this let them adjust their radars to settings they'd normally never adjust it to and caught the nighthawk with it's bomb doors open (the only time it gives off a real radar signature even with optimal settings)
