Planefag: UPDATE!
Appears our UK friends are going to land at Buckley AFB Colorado.
NVM, it turned left going S/SW at the moment.
I'm inclined to think that B2EPIC "could be" based upon using a sheet of paper, they are heading almost direct on with San Diego.
this aircraft's Altitude and airspeed suggest perhaps San Diego.. cruise altitude
It is a military aircraft. I have my filter set for military aircraft only.
You seem knowledgeable so, I'll stick with your thinking.
I'll see what I can come up with.
Looks like a path J-146 to Vegas NV.
I tried to write legibly. But circled Vegas Airport
Got it! I'll keep an eyes on it then. stay tuned.
