There's a fourth one lurking down FL way FINS55.
Might be some training going on with the regular flights could be shift change time.
If you look closely two of them are heading towards Offutt AFB. Looks like end of shift for them.
Looks like shift change keep calm.
Don't get your panties in a bunch. With 1 just landed it looks like shift changeover time.
They usually loiter near the coasts with two heading inland to the plains it looked pretty obvious to me.
Sudden altitude change is probably just lag in the updating.
GTMO341 heading S towards Gitmo.
Can't call yourself a planefag until you've snagged at least ten of these. KEK
TY for the info. o7
Strategic comms planes love playing hide & seek. Often the only time you see them is when they are in transit to their patrol/loiter areas.
