I've been on both sides of the game... Working at the Elmendorf AFB Air Operations Center in AK, we would track Russian Bear "ADIZ Pens" ("penetrations") across the pole or over the bearing sea, and launch our F-15s to go say, "Hi!". (F-22s, now). Working at the Hickam AFB AOC in Honolulu, we would schedule these FON flights for our west-pac areas of responsibility.
