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.
Yep, the “observers” I call spies.
During DS the earliest we took off was at dusk based on the mission profile, flight time to target, etc.
We were so far removed from the Iraq border that none had a chance to “know where and when” to look. The aircraft didn’t follow a prescribed egress/ingress flight path into Iraq everynight.
When leaving Italy to Serbia, they were flying in a corridor. Stupid, absolutely stupid or outright treachery...I vote for the latter.
