Happened to us over France in a Vulcan.
We had filed as OAT and a 4-Jet. The French asked for our aircraft which of course was forbidden under the existing EMSec. 4-jet we responded.
After a few more word games that asked us if we were Vulcan X-ray Mike 6 4 7.
Then the co said we had a pair of RCAF F104 on our starboard wing tip. The Boss then said that's not all, we have a pair of Mystere on the port.
