Seven Embry-Riddle c172’s.
This was a pair of KC10A's back in May, similarly flying really close together. Extra noisy when they went overhead.There were two pairs of B767 which I think were KC676s flying in eastern NC. They flew down from the north east somewhere. Kinda odd to see what appears to be two airliners flying on top of each other. I had not seen this before, even one pair would have been unusual but to see two pairs was really interesting. The pairs were not flying anywhere
Yeah, that is what I saw. The pairs where flying so close that the plane icons were right on each other sometimes or just very close which is why I noticed them. No separation at all.This was a pair of KC10A's back in May, similarly flying really close together. Extra noisy when they went overhead.

Going back into my replay (right over Reno NV at 2023-05-24 1650UTC if you care) it looks like they were flying within 50' altitude of each other, one in front of the other, occasionally FR shows them on top of each other, sometimes not.
Here is an Osprey in flight mode.
What is interesting is that if you look really close, there appears to be another plane under the Osprey. I have noticed this a few times and I don't know if they are refueling or something else is happening. I saw the a C17 the other night that had a barely seen plane under it. That C17 and a C130 were repeatedly flying over a drop zone at Fort Bragg so I assume they were doing parachute drops. Not sure why another plane was hidden under the C17.
I also have seen couple of USAF tankers flying almost on top of each other. Looking at the flight data, they were flying very close and at the same speed. I saw a 135 tanker the other night, they are easy to pick out of the clutter of aircraft because of their four engines, and it flew off the coast being followed by a C17, which is easy to spot for the same reason. I am pretty sure the C17 was refueling or practicing, because of they were flying on top of each other and matching speed. However, eventually one plane disappeared off the website and then the other one disappeared as they got further offshore. Other planes were showing up so they turned off their tracking devices.

I don't think the plane "overlapping" issues I am seeing is from a sending delay. I have only seen it a few times and there were NO other aircraft around. I wonder if the planes are doing something that triggers a change in the icons? Either some flight characteristic or a change to the tracking hardware. I have seen many of the military aircraft just disappear. There they are and then there they aint'.I think because of the delay in sending/reporting position that the maps don't show you exactly where the plane is at the moment (obviously), but this delay isn't consistent so sometimes two planes flying a fixed distance apart at a fixed velocity will appear to get farther apart or closer together, but they're really not. When I've watched pairs of tankers I can see that their airspeed & altitude aren't changing, but the icons on the map are playing games with either other which would require significant speed changes.
Not sure if that explains hte Osprey + friend though.
