A lot of "black, unmarked" helicopters are neither black, or unmarked. If they're military, they're dark green, with black lo-vis markings on
them. The markings are hard to see from under 100 feet, and almost impossible to see, unless you have a REALLY good camera from farther than that.
Military helicopters have been known to fly 100 miles or more to go to conferences, or even to visit the FAA and get their certifications renewed.
They'll go to the nearest large FAA office to get that done. They're required to be current with the physical, and the certification by the FAA.
We used to see about one an hour land at Honolulu when they were getting that renewed.
