We're near a non-military regional airport. Apparently the military likes the airspace above our neighborhoods to train Blackhawk crews. IDK which branch because the craft have zero insignia. Flightradar24 only id's them as Blackhawks.

They fly 1-3 at a time in a several mile loop. The parade begins late afternoon and ends at 10pm. I'm grateful we don't get the giant all-night FU, that the GP gets from their local LEO.
