The “mission planners”, NATO conops, NATO ROE, spies in Italy and an open weapons bay were the reasons 786 was shot down...they failed to follow the highly successful tactics used during DS to ensure the aircraft wouldn’t be compromised.
In my opinion, it was a deliberate act that cost us that aircraft and almost the pilot.
Sorry, not 786, 806...
Crewed both...
Not to mention the civilian observers in Italy that watched the F-117s take off and reported that back to the Serbs.
If you know where to look, and you know when to look, you can find them.
