military flights over US


#1

are there “standard” flight paths that the military flys? Almost daily I see sets of contrails, singles and sometimes as many as 3-5 in parallel, usually going east or west over north AL. but nothing shows up on Birmingham, Huntsville or Nashville areas activity views that match those flight paths. so I assume they are mil flights. usually too late to grab binoculars, but once did see what looked to be a pair of large AF tankers.
thanx

Do to it being military the flights don’t show on flight aware for security reasons.

I see these all the time over Denver and never manage to find aircraft type, destination or where it originated.
