Not trying to deboonk but the speed thing is not weird, planefags help me out but max airspeed is 600mph but with a tailwind it can go faster, like way faster so it could easily have been going like 500mph airspeed with a groundspeed of 600+
Correct. And because earth rotation, flights eastbound over the Atlantic often experience tailwinds that will take their ground speed well above the manufacturers stated maximum airspeed.
