Two Flights for One Plane

N757HW and N57HW is one plane. N757HW started the flight trackable then became “estimated” then the flight N57HW popped up and it became trackable until 5 minutes ago and that became estimated and now N575HW is trackable again. Don’t know if 6:59 is a good ETA or not?

Typos happen, looks like both flights have incomplete info.
