A good friend, who is sadly no longer with us, was on the usual NATO Wintex in Norway. At the time, he was flying Canberras and he was at either at Andoya or Bodo (I think). Suddenly, a FAF Mirage IV appeared in the circuit and landed. Apparently, it had become "unsure of its position" and was rather short of fuel. In the subsequent PU (which went on for some time) the navigator was given a new name tag by the RAF: "To Lose Le Track" which he sported for the rest of the night.
