I don't even see VENUS91. But…VENUS42 is circling Richmond now, same speed/altitude as VENUS91 (as you show).
SAM893 Clipper, VIP aboard, heading to Canada?
Most of those are fighters. My guess is readiness exercises.
Changed map for visibility.
VENUS42 making something in the sky. &?
VENUS42 is drawing an "X" over Richmond.
VENUS42 is now circling Newport News Int'l.
VENUS91 flying high and SLOW over GA now.
All just circling, then circling another airport.
