We see frequent Special Ops flights from bases in FL to Venezuela/Colombia/Honduras/Caribbean area. Usually they have a callsign MAGMAxx where xx may be 88, 89, 90, etc. Planefags NEVER post caps of those flights until they have feet wet on the way home, out of respect for the security of the op.
E.g. here is one from July 28
Usually Dornier Wolfhound like this one
The PAT78 callsign is familiar but never seen it overseas
