>”Original” Keystone a National Cemetary?
Yes anon remembers when there was a flight pattern of Arlingon National Cemetary flown by ANVIS.
Pic related!
It happened before January 4, 2019.
Planefag caps dates suggest the date was near Dec 17, 2018.
Still looking thru caps by date

Found a few more planefag working graphics whose layout mirrors Arlington National Cemetary?
Dec 16, 2018
AF1 went out and back, to make sure planefags noticed the pattern the ANVIS plane was flying. (pic2 12/16/2018)
Can’t find any more caps related to this incident.
Anybody want to use the keystone shape of Arlington National Cemetery, as traced out by the Navy ANVIS plane, to set the clock?
We established that the radial center of the pattern was the Naval Research Laboratory, Chesapeake Bay Detachment. (pics 3-4 Dec 18, 2018)
