So, the Russian S-300 or what ever it was couldn’t
tell friend from foe? Scary technology.
My favorite story is about an SR-71 during the Six Day War.
Israel was tossing up US-built AA missiles at it. The Arab countries couldn't react fast enough, let alone know it was an aircraft.
The reason for the daily fly-over was to get daily info on what Israel's equipment replacement needs were, among other things. Probably including the missiles...
Three refuelings, maybe each way, round trip from Langley.
That's just got to be a comforting thought to Russian pilots that their IFF transponder is not recognized by their AA equipment.
