Epic Cessna voyage

I'm not sure this this flight was spoopy enough to be notable DS activity, but it sure was epic for a Cessna Citation M2. I've just watched this one fly from (probably) northern California to Florida, about 2000nm by my calculations. The endurance of the M2 is variously reported at between 1,400 to 1,700 nm. I don't know if it was carrying extra fuel somehow or whether the winds at high altitude were the main factor, but in first (pic related) I guessed at the remaining range (pink circle) but it made it all the way to Florida.

The spoopiness that made me track it was it's callsign '2POSH' for a military aircraft, and the fact that it was a Danish operator of a UK military plane. And that it is so small!
