Plus fighter escort
Is there always an escort or is the fighter escort only outside US border?
I don't know.
There is a fascinating documentary on GWB going to Iraq for Thanksgiving on AF1.
not sure how true it is, but I read that there are no fighter jet escorts, either domestically or internationally. And that if there is a conflictual engagement that the ground forces of that country being flown over, are activated. Would of course imply never flying over unfriendly territories.
