Is this for real ?
I am just looking at BA 219 going in to Denver, expect delays because of +SN. About 600nm to go it drops of the screen and it has suddenly landed. 
Note the message to the right of the bottom portion of the map on the tracking page. It reads:
“At least part of this flight occurs outside of FlightAware’s service area. Information on this page may be unreliable.”
Some suggested reading material for you:

Thanks NeedleNose,
They are still of the map, is N and S Dakota( maybe over Nebraska now) somehow of limits? It still doesn’t make sense to me, it shows landed over an hour ago, they have not.
Why this error ?
Cheers
Looks like a border crossing issue… sometimes the data to us doesn’t go so smoothly over the US-Canadian border.
