It looks like it landed around 8 PM Saturday and didn’t return to flight until Sunday at 2 AM. So, not a single flight.
Look at speed
Look at the flight track. Looks like data corruption to me.
Blocked This flight is restricted from public view.
It’s not blocked here. But it’s also not a single flight, so there isn’t anything going on. The flights got all clumped together.
They did not have a flight plan filed and therefore FA has no way of determining if it was one flight or many.
