KIAG & KBUF Air to Air Refueling - Omega Air & CalSpan

Omega Air and CalSpan (N102VS) have been doing exercises over Lake Ontario Between Lewiston, NY and Rochester, NY.
CalSpan Has their Lear Jet up there, it’s an In-Flight Simulator and they are practicing air to air refueling.
Not something we see around this neck of the woods that often.
