Minding our own business on an established civilian airway in Saudi Arabia, during the trail of an RAF Tornado back to the UK, I was rather surprised to be'aggressively challenged' by some Spam in a boat somewhere on the Red Sea on 243.0:
"Unidentified aircraft at (our position), this is Red Crown on Guard. Identify yourself!"
"Say please!"
"Err, unidentified postion at (our position), please identify yourself"
"Ascot **** in company with Ascot *****, Halaifa 1014, FL220 estimating Wejh at 1037. As per Flight Plan!"
"Uhh, ahh, roger, you're cleared to proceed"
"Absolutely right. Goodbye"
Quite what the heck some Spam thought he was doing querying legitimately flight planned traffic in the airspace of a sovereign nation, I cannot imagine. Now wonder they're pretty unpopular in many parts of the world.
As for the Vincennes, the report makes appalling reading. A gung ho 'shoot 'em up' captain with overly aggressive attitudes and a crew who made ridiculous mistakes. A full and frank apology should have been made immediately the president discovered what his idiots had done.
